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

Inguaran Feb 2011 109a

By Jorge Cirett

During the 24th week of the year (June 10th to June 16th, 2019), at least 20 press releases were announced by companies working in Mexico. ON MEXICO ISSUES, the illegal blockade on Newmont Goldcorp’s Peñasquito mine in Zacatecas was lifted after 81 days, with negotiations between the parts to start on the following week. CAMIMEX proposed 90% of the Mining Fund should be allocated directly to the mining communities, this amid the presidential intention to use this fund at his sole discretion. ON EXPLORATION, In Baja California, One World Lithium completed the drilling program at Salar del Diablo. In Sonora, Aloro completed a drilling program at Los Venados; Ridgestone presented results of a bulk sample program at Rebeico. In Chihuahua, Ethos Gold commenced drilling at Purisima; Kootenay completed road building for its incoming drill program at Columba; Sable completed its second drilling campaign at Margarita; Radius reported results from drilling at its Amalia project. Advance Gold completed a 3D model for its Tabaqueña project. In Veracruz, Azucar presented results of seven more drill holes at El Cobre. ON MINING, No relevant news. ON FINANCING, Mako is to raise C$27 M, Aztec C$360 K and Minera Alamos had $400 K in warrants exercised. ON RESOURCES AND DEVELOPMENT, Mexus Gold started leaching at Santa Elena, in Sonora. Oroco clarified a statement on Santo Tomas resources from a previous news release. Impact Silver released sample results for the Manto America target area at Zacualpan. Candente informed positive results by partner Sun River Gold on metallurgical tests for the El Oro tailings. ON DEALS AND CORPORATE ISSUES, No relevant news.

ON MEXICO ISSUES

  • The illegal blockade on Newmont Goldcorp’s Peñasquito mine in Zacatecas was announced to be lifted on June 13th. Discussion panels between the parts are to be held starting on June 19th, sponsored by the Ministry of the Interior. The illegal blockade by a truck contractor and proprietors of communal land near the mine site lasted for 81 days. The truck contractor says it is fighting for employment whereas the communal proprietors claim water shortages caused by consumption by the mine (and the company alleges a plain extortion attempt).
  • CAMIMEX (Camara Minera de Mexico) proposed that 90% of the resources of the Mining Fund (Fondo Minero) stay within Municipalities, and the remaining 10% with the Mining Secretariat. Fernado Alanis, president of CAMIMEX, said that the original objective of the fund was to support the mining communities. On the former regulations only 50% of the funds reached the municipalities and the remaining to the coffers of the Federation and States, “but we believe the majority should reach the localities” (this proposal comes amid the presidential intention to deliver the Mining Fund as loans to people in mining communities, a move most in the industry see as a play to gain support for elections, and not helpful for supporting mining communities, originally the aim of such fund).

ON EXPLORATION

  • Ethos Gold Corp. commenced its drill program in the Purisima property in Chihuahua. The initial program will comprise 3,000 m of reverse circulation (RC) drilling in 15 holes, targeting shallow oxide bulk tonnage gold mineralization. “At La Purisima a northwest trending gold mineralized zone has been identified over a strike length of at least 2 km with a width of alteration and geochemically anomalous gold mineralization of approximately 600 metres. Within this footprint are two north-west striking zones that have the strongest gold anomalies, each approximately 200 metres wide.”
  • Aloro Mining Corp. completed 1,347 m of drilling in four holes at its Los Venados project in Sonora. The program aimed to test a blind mineralized felsic dome structure adjacent to the Mulatos mine’s high grade Escondida gold bearing felsic dome. Relevant intercepts comprise 3.05 m @ 0.14 gpt Au; 1.53 m @ 0.13 gpt Au; 3.05 m @ 0.22 gpt Au; 7.62 m @ 0.16 gpt Au.
  • Kootenay Silver Inc. has completed road building and signed a surface access agreement with the landowner at its Columba property in Chihuahua. Drilling is expected to start on the third week of June 2019.

ON RESOURCES AND DEVELOPMENT

  • Mexus Gold US. informed leaching has started at its Santa Elena mine in Sonora (not to mistake with First Majestic’s Santa Elena mine, also in Sonora). “Approximately 5700 tons of high-grade quartz vein material will be broken on site and hauled to the crushing and leaching site. The estimated grade for this material is in the order of 5 to 10 g/t Au.”
  • Oroco Resource Corp., at the request of IIROC clarifies a previous news release. The Mintec Inc. resource estimate included in the historical Bateman Report of 1994 for the Santo Tomas project in Sinaloa utilized a classification scheme other than those set out in NI-43-101. “A qualified person has not done sufficient work to classify the historical estimate as a current mineral resource or mineral reserve. However, the historical assaying and verification methods were performed within the accepted standards applicable at the time.”
  • Impact Silver Corp. released results from surface and underground sampling at the Manto America target area on its Zacualpan property in Estado de Mexico. More than 33 samples have returned greater than 2 gpt Au, peaking at 22.40 gpt Au.

 ON MEXICO ISSUES

  • Mexican mining projects raised interest for up to USD$ 8M of investment by companies from Canada, USA, Peru, Colombia, and Australia. According to the head of mining in the country, before realizing the investments, it will be necessary to carry out the work of convincing the surrounding populations. He said: “The type of mining we want is to pay taxes, be socially responsible and achieve economic benefits so that it reaches society and the settlement is public.” He insisted that the presidential mandate is that mining concessions will not be canceled and that the commitments acquired in the past will be honored. Among the areas with the greatest potential are in the south-southeast of Mexico, specifically the states of Oaxaca, Guerrero and Morelos, among others, with products such as Ag, Au, and Cu. The Ministry of Economy reported that the mining-metallurgical sector in Mexico contributes 4% of the national Gross Domestic Product. While in the world our country is the largest producer of Ag; it is among the top 10 producers of 16 different minerals: silver, bismuth, fluorite, celestite, wollastonite, cadmium, molybdenum, lead, zinc, diatomite, salt, barite, graphite, gypsum, gold and copper.

ON EXPLORATION

  • One World Lithium Inc., released drilling results from its Salar del Diablo project in Baja California Norte. The company has completed the first three holes of a twelve drill program, and reported that two holes located 14km apart have intersected aquifers with water samples containing pH values indicative of brines.

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

Inguaran Feb 2011 151 - copiaBy Jorge Cirett

During the 22nd week of the year (May 27th to June 2nd, 2019), at least 27 press releases were announced by companies working in Mexico. ON MEXICO ISSUES, on a move that is likely to paralyze the processing of documents at all regional offices of the Direccion General de Minas, the federal government fired all non-unionized workers. The Peñasquito mine in Zacatecas has now been closed by an illegal blockade for more than a month. ON EXPLORATION, In Sonora, Sonoro Metals provided an update on drilling at its Cerro Caliche property. In Chihuahua, Radius Gold released results on two more holes at its Amalia project. In Zacatecas, Galore Resources is mobilizing a rig to drill the El Alamo and Los Gemelos projects. ON MINING, Impact Silver, Telson Resources and Santacruz Silver presented its first quarter 2019 financial and/or operational results. Endeavour Silver updated on its performance plan. Camrova provided an update on mining and mine life plans for the Boleo mine in Baja. ON FINANCING, Prize Mining completed the first tranche of financing for $630 K; Ethos Gold announced a financing round intended to raise $225 K. Magna Gold completed a  private placement for CAD$2.67 M. Silver One is to start trading on the OTCQB Marketplace. ON RESOURCES AND DEVELOPMENT, Gold Resource released more drill results from its El Aguila project in Oaxaca. Fresnillo is investing US$5 M at La Cienega mine in Durango. GoGold released assay results from trenching at its Los Ricos property in Jalisco. Defiance Silver is drilling a geophysical anomaly along the Veta Grande vein system in Zacatecas. ON DEALS AND CORPORATE ISSUES, Radius Gold granted Panamerican Silver an option to earn up to 65% on the Amalia project, in Chihuahua. Magna Gold is to commence trading on June 5, 2019. The company optioned the Mercedes property and lately the Las Marias and Las Cabañas properties, in the vicinity Mercedes. Discovery Metals and Levon Resources combined their enterprises on an agreement that gives Discovery and Levon shareholders 50.4% and 49.6% ownership respectively. Altos Hornos de Mexico (AHMSA) bank accounts have begun unfreezing by Mexican authorities.

ON MEXICO ISSUES

  • The federal government fired all non-unionized workers from the regional offices of the Dirección General de Minas (Chihuahua, Durango, Guadalajara, Hermosillo, Puebla, Queretaro, Saltillo, Zacatecas), in a move that is very likely to paralyze the already slow pace of paperwork at this government branch. Releasing of ground for staking, issuing concession titles, title reductions, cartographic information and contract registration are just some of the processes likely to be affected by this event (Personnel reduction is a cost saving strategy by the present federal administration, strategy that is feared to be likely to result in the centralization, slowing and paralysis of many government services in the coming months).
  • The Peñasquito mine in Zacatecas has been now affected by an illegal blockade for more than a month. So far authorities at all levels continue to advise “negotiations” as the way to solve the illegal blockade, being careful not to mention any applicable law.

ON EXPLORATION

  • Galore Resources Inc. announced the mobilization of a drill rig to El Alamo project in Zacatecas. The 2,500 m diamond drill program can be followed by additional 1,500 m of drilling at Los Gemelos project, also in Zacatecas. El Alamo consists of Cretaceous sediments, mostly limestone with some siltstone and chert, with alteration and mineralization represented by varying amounts of silicification and iron-oxide bodies after sulfides. The target has a minimum strike length of 500 m and 200 m width. Trenching highlighted values of up to 20.4 gpt Au, whereas drilling encountered widespread anomalous gold, running up to 17.1 gpt Au. Coarse gold recovery by gravity was attempted at the nearby Los Gemelos property with a partner, but the agreement on such endeavor has been terminated due to the lack of results. The drill target at Los Gemelos are porphyry intrusive related gold-copper skarns.
  • Radius Gold Inc. has completed six diamond drill holes totaling 1,743 m at its Amalia project in Chihuahua. Assays have been received for the second and third holes (results on the first hole were previously released), highlighting the intercept of 5m @ 647 gpt Ag of white chalcedonic stockworks, silicification and hydrothermal breccias. The remaining three holes (results pending) cut wide intervals of moderate to strong silica and adularia alteration, brecciation, quartz sulphide veinlets and trace fine to moderate black sulphides.
  • Sonoro Metals Corp. provided an update on the last 20 holes at its Cerro Caliche project in Sonora. Highlighted intercepts comprise 9.15 m @ 1.26 gpt AuEq at Japoneses, 3.05 m @ 6.18 gpt AuEq; 9.14 m @ 1.33 gpt AuEq at La Española, 15.24 m @ 0.56 gpt AuEq at Guadalupe, 7.6 m @ 1.14 gpt AuEq at Chinos Altos, 10.67 m @ 1.06 gpt AuEq, and 10.67 m @ 0.74 gpt AuEq at Buena Suerte.

The plan involves “changes to mine-site management and contractors, changes to employee and contractor supervision, renting used mining equipment and leasing new mining equipment, and revising the 2019 mine plans for all four mines, particularly Guanacevi. The Company has cut operating and administrative costs, reduced the employee and contractor workforce by 18% and deferred all discretionary expenditures”.
  • Telson Mining Corp. reported first quarter 2019 financial results. At Campo Morado in Guerrero, 152.1 K tonnes of ore @ 4.25% Zn, 1.14% Pb, 118 gpt Ag, 1.08 gpt Au were mined at a daily rate of 1,811 tonnes (tpd); 148.3 K tonnes were processed (1,765 tpd), recovering 69% Zn, 33% Pb to produce 9.7 M Lb Zn, 1.5 M Lb Pb, 212.7 K Oz Ag, 895 Oz Au at cash cost of US$0.71 and AISC US$1.01 per Lb Zn produced, obtaining a mine operating profit of C$3.05 M.

  • Camrova Resources Inc. provided an update on the Boleo mine activities in Baja California Sur. The project is run by Korea Resources Corp, the majority shareholder, with Camrova holding a 7.24% stake that gives it rights to attend board meetings. For 2019 the production forecast of underground ore is 508 Kt @ 1.19% Cu and 2.44 Mt of open pit ore @ 80% Cu. Recoveries are expected to be 80.4% Cu, 29.9% Co, 4.2% Zn to produce 19,697 t of copper cathode, 419 t of cobalt and 1,016 t of zinc, resulting in negative free cash flow of $21M after payment of $25M in interest. It is also forecasted a 16 years mine life ending in 2034 by which time all debt is projected to be repaid, without a return of any of the capital that has been invested to date.

In addition, Hecla defined near-surface mineralization at the new El Toro area over 1.5km along strike and from surface up to 150m at depth. Drilling highlights at El Toro area include 750 g/t Ag and 4.9 g/Au over 1.8m, and 666 g/t Ag and 10.9 g/t Au over 1.3m.
  • Mexus Gold US, started blast hole drilling on the Julio vein system at its Santa Elena mine in Sonora to produce the ore necessary to initiate steady production. The material being drilled has been sampled and is averaging 4 g/t Au and 12 g/t Ag. “Mexus currently has over 12,000 tons of ore stockpiled and ready to mine which was a result of the preparation of the pit on the Julio vein”.
  • Premier Gold Mines Limited, released high grade intersects from underground drilling carried out at the Marianas zone within its Mercedes mine in Sonora. Significant results were in hole UG-MR19-011 with 4.96 g/t Au and 71 g/t Ag over 31m, including 25.65 g/t Au and 171 g/t Ag over 3.1m, hole UG-MR-19-007 with 4.51 g/t Au and 64 g/t Ag over 20.5m, including 11.04 g/t Au and 94 g/t Ag over 3.8m, and hole UG-MR10-010 with 7.29 g/t Au and 8 g/t Ag over 3.5m. “The Marianas Zone comprises the down-plunge extension of the main Mercedes mine trend. Previous surface drilling suggests Marianas has the potential to host economic mineralization of higher than the current reserve grade. It is the Company’s goal to convert a portion of Marianas mineral resources to mineral reserves with a delineation drill program during the balance of 2019. Ore development could commence in 2020”.
  • US Antimony, reported a doubling of its Madero, Coahuila Mexican smelter capacity with the startup of No.2 long rotary furnace. This is expected to double Mexican production by the end of Q2 due to the increased output of its Wadley mine in San Luis Potosi and its Guadalupe mine in Zacatecas.

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.

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.
