By Jorge Cirett
During the 41st week of the year (October 11th to October 17th, 2021), at least 25 press releases were announced by companies working in Mexico. To note, six companies posted exploration advances on their properties, six released Q3 reports and one on commencement of mining, two on financing and eight more on project development or resource definition and one more on mining concessions acquisitions. ON MEXICO ISSUES, Mexico’s president presented a proposal to change the law in the energy industry, but also restricting lithium exploration and production to the government. Several other elements could be included in the bill, referred to as “strategic minerals”, without elaborating, although a government party senator named cobalt, niquel, rare earths and even copper. ON EXPLORATION, In Sonora, Benjamin Hill Mining released results from geophysical processing and from fluid inclusion studies that support a buried intrusive source for the mineralization at the Benjamin Hill property; Canuc Resources updated on its deep drilling program at San Javier; Colibri Resources received the permit to drill Evelyn. In Chihuahua, Kootenay silver increased land holdings at its Columba project. In Sinaloa, Vizsla Silver presented drilling results from the Tajitos zone at its Panuco project. ON MINING, Guanajuato Silver commenced mining at El Cubo, in Guanajuato. First Majestic Silver, Golden Minerals, Gold Resource, Magna Gold, Aura Minerals and Avino Silver & Gold Mines presented its Q3 2021 reports. ON FINANCING, Candelaria Mining informed one of its lenders, Accendo Banco, had its operating permit revoked by Mexican authorities. Xali Gold announced Sun River Gold arranged a financing for US$6.5 M for the tailings project at El Oro, Estado de Mexico.

ON SOCIAL RESPONSIBILITY, Minera Media Luna, Peñols, Newmont Peñasquito and Pan American Silver informed on community programs in education and health.
ON MEXICO ISSUES
- Mexico is far from being a powerhouse in lithium production according to the Statistical Review of World Energy 2021 by BP. Australia, Chile and China hold 81.2% of reserves and 86.5% of lithium production, whereas Argentina, Brazil, Portugal, the United States and Zimbabwe account for 20.5% of reserves and 12.8% of the production. Camimex (Cámara Minera de México) points that the constitutional reform presented by the Mexican president lacks technical support, as even if there are several lithium projects in Mexico, none has proven economic viability. The most visible of these projects, in Sonora, is said to be the largest lithium prospect in the Globe, but its economic viability has still to be proven, as to date there is not a single mine of lithium in clays in the World.
- Mexico will not grant lithium concessions, said the Mexican president. He stated that even if his electricity reform is not approved by congress, his government has the power to reject any request for a concession to mine lithium. “We will deny any request for a concession to mine lithium and we have the power to do so. We want this to be established in the constitution, lithium belongs to the state”.
- Nationalistic views with control on “strategic minerals” have been voiced by Morena, the party in power in Mexico. Besides the explicit aim by the President to save all lithium extracting and processing activities for the government, his recent proposal also refers, without elaborating, to be applied in other “strategic minerals”. A senator form Morena mentioned these other minerals could include cobalt, nickel, rare earths and copper, although a spokeswoman from the Economy Secretariat mentioned that the list of strategic minerals was to be provided by the Mexican Geological Survey at a later date.
ON EXPLORATION
- Canuc Resources Corp. updated on the exploration program at its San Javier project in Sonora. Three holes have been completed and a fourth one is in progress, currently at 922 m of depth and ongoing. Chalcopyrite has been encountered from 302 m and is still visible at 922 m of depth. “The drill hole has intersected a broad zone of variably stockworked and brecciated Barranca sediments with minor andesitic dykes. The Barranca sediments show contact metamorphism from about 461 m and downward, variable amounts of magnetite bearing veinlets, stringers and breccia matrix throughout”. The first two holes intercepted Barranca Formation sedimentary rocks with magnetite veinlets and best intercepts of 2.35 m @ 126 gpt Ag and 2.0 m @ 243 gpt Ag. The third hole was drilled on the Tarahumara Formation volcanic rocks for 500.5 m before being terminated due to drilling problems, intercepting several volcanic lithologies, chalcocite from 38 m of depth and sulfides including chalcopyrite from 332 m. Scattered gold and copper values on short intervals were intercepted, of up to 1.19 gpt Au and 0.41% Cu. Results for the current hole are still pending.
- Colibri Resource Corp. received the needed permit to drill up to 56 holes at the Evelyn project in Sonora. “The fully funded drill program of up to 10,000 metres is expected to be conducted in two phases”.
- Kootenay Silver Inc. increased its land holdings at its Columba project in Chihuahua. The company applied for a 10,825 hectare concession, supporting the decision to do so on the high-grade silver intercepts on drilling of the property.
- Vizsla Silver Corp. presented the results from 23 new drill holes from the Tajitos vein at its Panuco project in Sinaloa. Highlighted true width intercepts comprise 1.38 m @ 1.16 gpt Au, 79 gpt Ag; 1.34 m @ 7.94 gpt Au, 960 gpt Ag; 0.70 m @ 4.16 gpt Au, 2,082 gpt Ag; 2.15 m @ 1.09 gpt Au, 188 gpt Ag; 1.38 m @ 2.83 gpt Au, 527 gpt Ag; 8.7 m @ 0.51 gpt Au, 99 gpt Ag; 1.99 m @ 2.46 gpt Au, 615 gpt Ag; 0.86 m @ 3.37 gpt Au, 315 gpt Ag; 1.39 m @ 3.26 gpt Au, 73 gpt Ag; 1.3 m @ 2.47 gpt Au, 600 gpt Ag; 1.50 m @ 9.90 gpt Au, 2,607 gpt Ag; 0.7 m @ 5.73 gpt Au, 1,115 gpt Ag; 4.38 m @ 1.62 gpt Au, 216 gpt Ag. The footprint of the Tajitos zone has been recognized for 800 m along strike and 300 m of depth.
- Benjamin Hill Mining Corp. informed the seven kilometer long trend of epithermal mineralization at its Benjamin Hill project in Sonora is related to a well-defined magnetic anomaly. A magnetic high more than 12 kilometers long and 4 km wide lies beneath the surface, crossing the property in a N-NE orientation, with the Au-Cu mineralization parallel to the crest of the magnetic high. “Our hypothesis explains that the magnetic anomaly corresponds to a partially exhumed fertile pluton. We suggest the mineralization seen at surface was driven by the heat engine of a buried pluton providing hydrothermal fluids that formed mineralized tabular bodies enriched with Au, Ag, and Cu (i.e. veins and breccias), as well as fluids that caused hydrothermal alteration halos (phyllic, epidote-magnetite and argillic alteration)…”.
- Mammoth Resources Corp. updated on drilling at its Tenoriba project in Chihuahua. The company informed heavy rainfall during August and September is subduing by now, and that they expect an increase in the drilling rate that produced only 420 m of core in 8 weeks. “Mammoth intends to initially drill 2 – 4 holes within each target zone then move to another target zone to drill a similar number of holes”. Results on the first holes are pending.
- Benjamin Hill Mining Corp. informed on results of fluid inclusion studies at its Benjamin Hill property in Sonora. The salinity and homogenization temperatures point to an epithermal system with an overprinting magmatic influence, and exhumation depths between 150 m and 750 m in the mineralized structures. “This observation combined with recent geophysical data, supports the hypothesis of the existence of a mineralized plutonic source with a high possibility for Au-Cu metallic enrichment and porphyry potential”.

ON DEALS AND CORPORATE ISSUES, Orex Minerals and Pan American Silver entered into an agreement to negotiate a formal JV agreement on the Sandra Escobar project in Durango. Oroco Resources signed a letter of agreement to acquire the 766 ha. Rossy concession adjacent to Oroco’s land package on the Santo Tomas district in Sinaloa.
ON MEXICO ISSUES
- Camimex (Cámara Minera de México), informed on a list of new gold producing projects that involve the investment of US$2,705 M between 2019 and 2024. Among the biggest investments are those of Torex Gold (US$482 M) in Media Luna, Guerrero; Grupo Mexico’s (US$413 M) Buenavista Zinc in Sonora and Fresnillo’s (US$350 M) Orisyvo in Chihuahua. Other investments include the second dynamic leaching plant at La Herradura; the Pyrites plant in Fresnillo; Goldcorp’s Pyrite plant in Peñasquito, Zacatecas; and Endeavour’s El Compas in Zacatecas; Candelaria Mining is to start operations at Pinos, Zacatecas; Mag Silver and Fresnillo are to begin production at Juanicipio, Zacatecas; Telson Resources is to finish construction of the mine at Tahuehueto, Durango; Hecla’s will continue with open pit and then underground operations at San Sebastian, Durango.
- Camimex stated that during 2018 Mexico’s gold production diminished 6.7% compared with 2017, reaching 3.8 M Oz Au. Five companies produced more than half of the overall gold production in 2018: Fresnillo (24.1%), Torex Gold (9.3%), Agnico Eagle (8.5%), Goldcorp (7.1%) and Minera Frisco (6.5%) (Editor’s note.- This last company has the dubious honor of being the most opaque for disclosing production, reserves and resources from its projects in Mexico).
ON EXPLORATION
- Sable Resources Ltd. has received the permit needed to drill the Vinata project in Chihuahua. The surface agreements have been approved by the local community for an initial 2,500 m diamond drill program “to test the vertical continuity and mineral zoning along a section of the Vinata vein system where the veins are observed outcropping over 1000 m along strike”. Sable will contract a ground electromagnetic survey (CSAMT) to better define the vein system at depth and the contacts between a felsic dome and volcanic and sedimentary rocks. The mineralisation at Vinata occurs as a series of quartz veins that outcrop for 1,200 m, with multiple sub-parallel veins and stockwork zones over a width of 15 to 170 m, with individual veins ranging to up to 12 m in width.
- One World Lithium Inc. released results from drilling at its Salar del Diablo property in Baja California (there is not a state named Baja California Norte in Mexico). The drill holes did not reach the target depths due to “the constant sluffing of sand, presence of multiple clay formations, unconsolidated gravel and rubble”. The highest lithum grade in sediment samples was 273 ppm Li, whereas the water samples are thought to have been diluted by the injection of significant amounts of fresh water while drilling. The Company intends to resume its 4,250 foot drilling program before the end of September 2019.
- Discovery Metals Corp. has been granted drilling permits for its Monclova project in Coahuila. “The Real Viejo area is the key near-term target. It hosts five historic shallow underground mines along a strike of 1.5km at a limestone-intrusive rock contact”, with rock channel samples averaging 277 gpt Ag, 6.7% Zn, 1.9% Pb. The Real Viejo area is 2 square-km in size and is located along the southern contact of the Monclova intrusive complex, where a series of Ag-ZnPb mineralised, silica-rich vein, replacement bodies (mantos), skarn-altered embayment zones and breccias 2-10 m wide are located.
- Fresnillo Plc. is realizing exploration work in the Guanajuato district, mainly near Mineral de La Luz.
- Magna Gold Corp. initiated its phase one exploration program on the Mercedes project in Sonora. The aim on this phase is to confirm the existence (suggested by historical drilling) of an oxide zone of quartz stockwork Au-Ag mineralisation 60 m wide and 220 m long, and a surface study including geological mapping of a 500 ha zone and systematic rock chip and soil geochemical surveys.
ON MINING

The Mining and Exploration News in Mexico: Highlights on the Second Week of June, 2019

By Jorge Cirett
During the 26th week of the year (June 24th to June 30th, 2019), at least 43 press releases were announced by companies working in Mexico. ON MEXICO ISSUES, a resolution by the Supreme Court is awaited to learn how the Mining Fund resources are to be allocated, if for social and environmental infrastructure (as planned) or as direct allocations to the people of the communities, the preferred method of the president (a method the opposition denounces as vote buying). In Sonora a local congressman introduced a bill for a new state tax on dirt extracted from open pits, a measure that if implemented is to pose a further weight in the already heavy fiscal load for mining companies in Mexico. Furthermore, the Economy Secretariat (Secretaria de Economia) published a letter stating that the “Protocol of Good Practice of Mining for the Public Consultation” (Protocolo de buenas practicas de la Minería para la consulta pública) is under review by the agency. It is not possible to underrate the importance of the review of this protocol, because if it is implemented incorrectly the result would impact fast and catastrophically the Mexican exploration industry. One of the more pressing issues is the fact that placing the consultation process before exploration takes place, would end most exploration in one swipe. If in doubt, just take a look to Oaxaca, where, although not being in the law you have to make the community consultation process before exploring, and the result is that hardly any exploration work is nowadays conducted in one of the states with the best mineralization potential in Mexico. Trust is hard to earn, let’s not throw it away so carelessly. ON EXPLORATION, In Zacatecas, Galore continues to drill at Dos Santos; Alien Metals updated on its exploration of Donovan 2 and Los Campos. ON MINING, Alien Metals released its financial results for 2018. ON FINANCING, Santacruz signed an agreement to extend the payment of a US$2.3 M loan. Galore is making a $1.5 M financing. Goldplay closed an oversubscribed financing for $1.37 M. Leagold completed a debt refinancing for a $200 M term loan and a $200 M revolving credit facility. ePower intends to conduct a private placement for Cdn$6 M. Sable granted 2.8 M incentive stock options. Alien Metals raised £350 K. ON RESOURCES AND DEVELOPMENT, Mexus Gold is to start leaching at Santa Elena, in Sonora. Telson reported significant underground channel sample results at Tahuehueto. Orla presented the result of the FS on Camino Rojo. Premier Gold presented results of its 42,000 m drilling campaign at Mercedes. Southern Silver file a technical report with updated resources on Cerro Las Minas. Santacruz presented results of drilling at Veta Grande. GoGold released results of drilling at Los Ricos. SilverCrest informed the decline has intersected the Babicanora vein at Las Chispas. Minera Alamos informed on the permitting of Santana. Almaden updated on permitting and legal issues at its Ixtaca project in Puebla. ON DEALS AND CORPORATE ISSUES, Millrock sold its Sonoran portfolio to Riverside. ePower Metals entered into a definitive agreement with Minera Alamos to acquire the Los Reyes project in Sinaloa. Silver Viper renegotiated much better terms on the lease of two properties within its La Virgina project in Sonora. Golden Minerals entered into an agreement under which Minera Autlan is to buy its Velardeña properties. Bacanora Lithoum signed an investment agreement and an offtake agreement with Ganfeng Lithium on its Sonora lithium project. Canasil and Pan American agreed on terms for the acquisition of Pan American of the Sandra Escobar project in Durango.
ON MEXICO ISSUES
- The Economy Secretariat is awaiting the resolution of the Supreme Court on the change of rules to apply the Mining Fund, which this year is anticipated to be amounting to 3.2 billion pesos (3,200 millones) or approximately US$168.4 M. The proposal by the present Federal government (ie.- the president) is to deliver the resources directly to the people to “augment the capacities” of the mining communities. The aim would be to organize the community and the service providers to be part of the service chain for the mining industry. The resources on the Mining Fund to date are to be funneled according with the current rules, until a resolution by the Supreme Court clarifies the issue.
- In Sonora, local congressman Carlos Navarrete from the Encuentro Social party (allied to the Morena party) introduced a bill for a new State tax on dirt extracted from open pits (includes waste, sand, dimension stone, clays, limestone, lime, among others). The US$0.63 tax per cubic metre of material would be split 80/20 between the municipalities and the State. The resources would be utilized in physical investments and infrastructure with social impact, in the environment and urban development (The bill intends to use the resources thus gathered in the same way that those of the Mining Fund were supposed to be used, and for which a 7% federal royalty tax was imposed on mining a few years ago. Now that the current president Andrés Manuel Lopez Obrador intends to use the resources of the Mining Fund for his preferred programs, allied politicians are trying to make the mining industry pay even more taxes).
- The Economy Secretariat published a letter on the “Protocol of Good Practice of Mining for the Public Consultation”. In the letter the Economy Secretariat states that the protocol is under review by the agency. On the Letter: The consultation process is to be applied to all communities that can be impacted by the mining activity. Also, both exploration and exploitation should be consulted before their realization. The responsible authority is to be the Economy Secretariat, with aid by the Instituto Nacional de los Pueblos Indigenas and other authorities (SEMARNAT, CONAGUA, CFE, local municipal and state governments), as well as the state and federal Human Rights Commissions.
ON EXPLORATION
- Galore Resources Inc. informed its 2,500 m diamond core drilling program at the El Alamo target of its Dos Santos project in Zacatecas continues to progress well. The first hole “intersected multiple zones of alteration and brecciation …… silicified and brecciated limestone similar to those observed on the surface over a much wider zone than was anticipated”.
- Alien Metals Ltd. updated on its exploration activities at its Zacatecas properties Donovan 2, Los Campos and Don Celso. Sampling and mapping at Donovan 2 has resulted in high grade mineralisation in historic workings open along strike, and channel sample assays of up to 1.15% Cu and float samples of up to 0.45 gpt Au. Planned work includes a ground induced polarisation (IP) geophysical survey before the first phase of drilling. Surface mapping and sampling will be undertaken at Los Campos and Don Celso properties, as well as underground sampling and a geophysical survey at Los Campos.
ON MINING
- Alien Metals Ltd. released its audited financial results for 2018. The company owns the Donovan 2, Los Campos, San Celso and La Africana projects in Zacatecas. The company held US$0.7 M in cash and cash equivalents by the end of the period.
ON FINANCING
- Santacruz Silver Mining Ltd. reached an agreement to amend the repayment terms of the US$2.3 M short-term loan that it has borrowed from a private Bolivian mining company. The principal balance of US$2.3 million is now to be repaid by January 30, 2020. As consideration for the extension on the date of repayment Santacruz is to increase the issue of 2 M warrants to 2.5 M warrants (Veta Grande, Zacatecas).
- Galore Resources Inc. is to commence a non-brokered private placement to raise gross proceeds of up to $1.5 M (Dos Santos, Zacatecas).
- Goldplay Exploration Ltd. closed its over-subscribed previously announced financing, for gross proceeds of $1.37 M. A total of $28.9 K was paid and 231 K warrants were issued as a finder’s fee payment (San Marcial, Sinaloa).
- Leagold Mining Corp. completed the debt refinancing with a syndicate of lenders that includes a $200 million term loan and a $200 million revolving credit facility. These loans have been used to replace $238 million of existing short-term debt, and will aid in the development of the Bermejal underground complex, the Guadalupe open pit and the CIL plant construction at it Los Filos mine in Guerrero.
- ePower Metals Inc. intends to conduct a non-brokered private placement to raise up to Cdn$6 M (Los Reyes, Sinaloa).
- Sable Resources Ltd. granted 2.8 M incentive stock options to certain officers, directors, employees and consultants of the company. Such options are exercisable at a price of $0.15 for a period of five years (Margarita and Vinata, Chihuahua).
- Alien Metals Ltd. raised £350 K through the placement of shares (Donovan 2, Los Campos, Zacatecas).
ON RESOURCES AND DEVELOPMENT
- Mexus Gold US. is to start leaching at its Santa Elena mine in Sonora (not to mistake for First Majestic’s Santa Elena mine, also in Sonora). Leaching is programmed to start on June 27th, with ore grading 1.8 gpt Au, 8 gpt Ag, to later on add ore @ 4 gpt Au, 12 gpt Ag. By September the company expects to be mining 3,500 tonnes per week.
- Telson Mining Corp. reported significant channel sample assay results for underground mine development at its Tahuehueto project in Durango, where a 1,000 tonne per day mine is under construction. Highlighted results include: 2.42 m @ 5.76 gpt Au, 129 gpt Ag, 1.44% Cu, 3.8% Pb, 6.2% Zn; 5.50 m @ 3.31 gpt Au, 57 gpt Ag, 0.32% Cu, 0.9% Pb, 3.5% Zn; 5.38 m @ 4.41 gpt Au, 44 gpt Ag, 0.38% Cu, 1.5% Pb, 3.6% Zn; 7.0 m @ 5.12 gpt Au, 40 gpt Ag, 0.29% Cu, 1.0% Pb, 3.2% Zn; 6.45 m @ 5.69 gpt Au, 51 gpt Ag, 0.21% Cu, 2.3% Pb, 5.6% Zn; 4.42 m @ 8.70 gpt Au, 59 gpt Ag, 0.18% Cu, 1.7% Pb, 2.2% Zn; 4.08 m @ 9.27 gpt Au, 69 gpt Ag, 0.19% Cu, 0.6% Pb, 1.0% Zn; 3.56 m @ 7.95 gpt Au, 76 gpt Ag, 0.25% Cu, 3.3% Pb, 4.6% Zn.

The Mining and Exploration News in Mexico: Highlights on the First Week of May, 2019

By Jorge Cirett
During the 18th week of the year (April 29th to May 5th, 2019), at least 35 press releases were announced by companies working in Mexico. ON MEXICO ISSUES, Newmont Goldcorp Corp. informed on the intention to temporarily suspend operations at the Peñasquito mine in Zacatecas, due to an illegal blockade lasting for more than a month now. More than 300 mine employees protested outside the Zacatecas Congress, accusing José Narro, senator by Morena (the president’s party) of instigating the blockade. Drill core from La Xora project in Nayarit was added to The Mexican Core Shack. ON EXPLORATION, Nine companies presented advances in the exploration of their properties: In Baja, One World Lithium has received the permits to drill its Salar Del Diablo property. In Sonora, Sonoro Metals disclosed assays for the first 15 RC holes of the second drilling campaign; Ridgestone updated the work done to date at Rebeico; Minaurum staked a large chunk of ground at its Alamos project. In Chihuahua, Silver Spruce released surface sample results from its Pino de Plata project; Radius Gold released exciting results from the first hole of the second drilling campaign at Amalia; Kootenay Silver has initiated drill road construction for its incoming campaign at Columba. In Jalisco, GoGold released results from its drilling campaign at Los Ricos. In Zacatecas, Alien Gold updated on the exploration effort at its Donovan 2 property. ON MINING, nine companies presented its first quarter 2019 results, while one company presented its 2018 results. ON FINANCING, First Mining, and Prize Mining are to raise $6 M and $1.5 M respectively. Leagold Mining secured a 200 M term loan and a 200 M revolving credit. ON RESOURCES AND DEVELOPMENT, no relevant news. ON DEALS AND CORPORATE ISSUES, Alio Gold received notice of a civil claim from a former Rye Patch shareholder.
ON MEXICO ISSUES
- Newmont Goldcorp Corp. informed on the intention to temporarily suspend operations at the Peñasquito mine in Zacatecas (one of the largest in Mexico, produced 272 K Oz Au in 2018), due to an illegal blockade by a trucking contractor and some members of the Cedros community that began on March 27, 2019. The company announced on April 9 that the trucking contracts will now be signed with independent truckers, to their economic benefit and to avoid the repeated extortion blockades by the current trucking contractor. Newmont Goldcorp denounced that the blockader’s public claims that focus in water quality and employment, turn in a direct petition for large amounts of money when done privately. The company asks for help from the Mexican and Zacatecan authorities to resolve the illegal blockade that affects the income of more than 20 thousand persons, directly or indirectly. On a different event, about 300 employees of Minera Peñasquito, protested outside the Zacatecas Congress against the illegal blockade that keeps paralyzed the Peñasquito mine. The protesters accused Jose Narro, senator by the president party, Morena, and his acolyte Felipe Pinedo of blackmailing the company with false water contamination statements.
- Core from La Xora project, in Nayarit, was added to the Mexican Core Shack (https://gambusinoprospector.com/mexican-core-shack/), under the epithermal low sulphidation section.
ON EXPLORATION
- Sonoro Metals Corp. reported assay results from the first 15 reverse circulation holes of the second phase drilling program at its Cerro Caliche property in Sonora. All holes encountered gold mineralization, which extend mineralization 1.25 Km NW from the Central Zone, where the first drill campaign defined a series of NW striking structures, outlining three shallow bulk tonnage oxidized mineralized zones in metasedimentary and volcanic rocks. Previously reported results come from the Central Zone prospects Japoneses, Abejas, El Colorado and Guadalupe, whereas the new drill holes tested El Rincon, Gloria, El Boludito, and Veta de Oro zones. Highlighted results comprise 10.67 m @ 2.73 gpt AuEq; 3.05 m @ 5.48 gpt AuEq; 10.67 m @ 0.74 gpt AuEq; 6.1 m @ 0.80 gpt AuEq; 15.24 m @ 1.05 gpt AuEq.
- Alien Metals Ltd. updated on its exploration work at its Donovan 2 project in Zacatecas. Work to date supports indications of volcanogenic massive sulphide (VMS) mineralisation on multiple target areas open along strike, with surface assays of up to 3.3% Cu, 0.25% Zn. Currently there are magnetic, chargeabilty and resistivity anomalies, and a gravity survey underway is to refine the targets on this project, which is 24 kilometers from Teck’s San Nicolas deposit.
- Ridgestone Mining Inc. announced that exploration work to date on its Rebeico property in Sonora defined the 1.2 km long Alaska vein and intensely altered breccia zones SW of the vein, carrying Cu, Au and Ag values, as well as bismuth anomalies. An 18 line-kilometer induced polarization (IP) survey identified a chargeability anomaly below the breccia zone. A 12 hole 1,430 m diamond drill program tested 500 m of the Alaska vein. Eight of the twelve holes intersected significant grades, including: 0.80 m @ 1.41% Cu, 2.95 gpt Au; 2.0 m @ 2.78% Cu, 8.69 gpt Au; 1.40 m @ 3.25 gpt Au; 1.50 m @ 1.39 gpt Au; 1.0 m @ 0.30% Cu, 5.61 gpt Au; 3.25 m @ 2.41% Cu, 8.31 gpt Au; 1.50 m @ 1.22% Cu, 36.10 gpt Au.
- One World Lithium Inc. has received the permit required to start its 12 hole, 4,250 m drilling program at its Salar del Diablo property in Baja California. The company intends to test three geophysical anomalies, a geochemical anomaly, and structures that may trap and concentrate brines. The Salar del Diablo Property has never been drilled in the past.
- Silver Spruce Resources Inc. released surface sample results from its Pino de Plata property in Chihuahua. The samples returned 19 gpt Ag, 16 gpt Ag, 2 gpt Ag, 1,1,30 gpt Ag, 123 gpt Ag, 95 gpt Ag and 255 gpt Ag; up to 0.19 gpt Au, up to 802 ppm Cu, up to 3.7% Pb on samples 0.2 to 1.0 m in length. The two targets in the area comprise El Terrero and the Gossan area. At El Terrero, a 32 hectares zone “of multiple flat-lying brecciated zones hosted by a zone of strong argillic alteration” is the target, while at the Gossan area a series of hornfels and skarns developed near an intrusive contact may host massive sulphide replacement bodies associated to structures.
- Radius Gold Inc. reported the first results from the second diamond drill campaign at its Amalia project in Chihuahua. The program is operated by Radius and funded by Pan American Silver Corp. under a JV agreement by Which Pan American can earn an initial 65% by making cash payments totaling US$1.5 M (of which US$100 K have been paid) and spending US$2 M on exploration over four years. The first hole in this campaign intersected 44 m @ 12.38 gpt Au, 309 gpt Ag, including 11 m @ 39.9 gpt Au, 323 gpt Ag. The estimated true width of the zone is 34 m, consisting of “an epithermal breccia and quartz sulphide stockwork vein zone ” located on or near to the contact between overlying Tertiary rhyolitic ignimbrite and the footwall andesite volcaniclastics of the Late Cretaceous Tarahumara Formation. Diorite dykes appear to be emplaced along the fault zone and are associated with mineralization”.
- Minaurum Gold Inc. staked an additional 20,872 hectares on its Alamos project in Sonora. Additionally, mapping has revealed four new vein zones: Rosario, La Dura Oeste, La Dura and La Tijera. These four zones bring the total of veins zones of the district to twenty. The Rosario vein has been traced for 500 m, with samples assaying 304 gpt Ag and 227 gpt Ag over 1 m and 675 gpt Ag, 1.0% Cu, 0.9% Pb over 2 m. The La Dura Oeste vein has been traced for 550 m, returning assays of 30 gpt Ag, 3.4% Cu and 37 gpt Ag, 4.3% Pb. La Dura vein returned 123 gpt Ag, 2.% Cu over 0.5 m.
