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. La Tijera vein was traced for 750 m, with three samples returning 23- 36 gpt Ag, 0.41 – 0.77% Cu, up to 0.1% Pb, up to 0.15% Zn over 0.1 to 0.3 m.
  • Kootenay Silver Inc. has initiated the road construction for the drilling of its Columba property in Chihuahua. The property covers a low sulphidation epithermal system with numerous veins ranging on 200 m to up to 2 km of strike length. Over 1,000 m of underground workings are present, including four shafts and six drifts, with historic records indicating grades between 600 and 900 gpt Ag.
  • GoGold Resources Inc. released results from its recently acquired Los Ricos property in Jalisco. Highlighted diamond drill results comprise 22.4 m @ 4.13 gpt Au, 182 gpt Ag (or 6.55 gpt AuEq), including 3.0 m @ 25.08 gpt Au, 534 gpt Ag (or 32.2 gpt AuEq) and 11.7 m @ 0.68 gpt Au, 89 gpt Ag (or 1.87 gpt Au), including 6.1 m @ 0.58 gpt Au, 142 gpt Ag (or 2.47 gpt AuEq).

At the Central prospect, one of the two holes drilled intersected several 3 to 6m wide structures returning silver values ranging from 11 to 30 g/t. At Lucy prospect, two holes tested skarn/carbonate replacement manto mineralization. Drilling results returned 22m of 0.33 g/t Au and 1.5 % Zn; and 25m of 0.6 g/t Au, 22 g/t Ag, 0.25% Cu, and 1.6% Zn. At Sundae prospect, the company has identified a 3km long high level-low sulphidation epithermal system that runs for over 3km along strike, with individual structures varying from 1-5m in width. A preliminary geophysical survey showed a continuity of the vein host structures to over 500m depth. At Los Mimbres prospect, skarn and hornfels boulders with Cu and Pb sulphide mineralization were recently discovered adding a new target within the Yarely project. Mineralization identified at Los Mimbres is similar to that encountered at Metates. Stream sediment, soil, rock geochemistry and geological mapping are underway to advance this target to the drill stage.
  • Excellon Resources Inc., commenced a 3,000m drill program at its Miguel Auza project in Zacatecas to test targets generated from surface mapping, IP surveying, and structural work conducted since mid-2017 at El Cobre, Abejas, Carmen-Lechuzas, and Lomo de Las Minas prospects. Highlights from the surface sampling are 2.3 g/t Au and 667 g/t Ag at Lomo de Las Minas. Results up to 2.9 g/t Au and 300 g/t Ag were sampled at Carmen and El Cobre confirming mineralization in veins at both targets. Mineralization at Miguel Auza is hosted in epithermal quartz veins similar to those found at Fresnillo mining district.
  • Defiance Silver Corp., defined a significant geophysical anomaly at its San Acacio project in Zacatecas employing Atomic Energy Resonance Imaging (AERI) technology. The AERI identified a pipe shaped anomaly which measures 400m in width, 300m in length, and is open at depth. The AERI anomaly is coincident with a recently delineated IP target, and will be drill tested in the near future.

Highlights on the Third Week of December, 2017. Mineral Exploration in Mexico

During the 51st week of the year (December 18th to December 24th, 2017), at least 17 press releases were announced by companies working in Mexico. ON MEXICO ISSUES: The illegal blockade promoted by the Los Mineros Union since November 3, 2017 is showing how far the government is willing to go, or not, to establish the rule of law. ON EXPLORATION: two press releases from companies working in Mexico informed on exploration efforts during the week: In Chihuahua Radius Gold released good rock chip results from its Amalia project. In Sinaloa Gainey Capital is exploring the La Minita porphyry copper style property.  ON MINING: Great Panther announced government authorization for the construction of a second tailings storage facility at its Topia mine in Durango. Mexus Gold produced gold with a Merrill Crowe system installed at its Santa Elena mine in Sonora. Americas Silver announced the San Rafael mine at its Cosala complex is now on commercial production. ON FINANCING: Telson Resources entered into a US$15 M loan with Trafigura. SilverCrest completed a bought deal private placement for $10 M. Primero Mining agreed on an extension to its revolving credit facility. Torex Gold received a waiver to lower the threshold in the credit agreement from $50 M to $30 M. ON RESOURCES AND DEVELOPMENT: In Sonora, Oceanus Resources presented an update on the drilling of its El Tigre property. In Chihuahua, Consolidated Zinc announced the interception of massive sulfides on the Tres Amigos zone of its Plomosas property. In Puebla, Almaden released new results from follow-up  drilling at its Tuligtic property.  In Guerrero, Alio Gold provided the final results of the confirmation drilling at its Ana Paula project. ON DEALS AND CORPORATE ISSUES, Torex Gold suspended its workforce employment contracts on the basis of the illegal blockade that has halted all operations since November 3rd at its El Limon-Guajes mine in Guerrero. The company has made a call to the relevant authorities to remove the illegal blockade (which seems to have fallen on deaf ears). Orex Minerals, Canasil Resources and Pan American Silver signed an agreement to advance the Sandra Escobar project in Durango, same that includes provisions for Pan American participation on the discovery. Gainey Capital signed a LOI to acquire the La Minita property in Sinaloa. Marlin Gold can now spin-off its subsidiary Sailfish Royalty. Vangold is acquiring the San Carlos claim in Guanajuato, adjacent to its Pinguico property. Americas Silver agreed with Hochschild to amend the payment schedule on the acquisition of the San Felipe project in Sonora.

ON MEXICO ISSUES

  • On the Torex Gold El Limon – Guajes mine illegal blockade in Guerrero (Editor’s comment). The illegal blockade promoted by the Los Mineros Union since November 3, 2017 is showing how far the government is willing to go, or not, to establish the rule of law. The Los Mineros Union is clearly trying to extortionate Torex with an illegal blockade to obtain the Union contract at the site, and delaying the date for a formal voting process that the company has vowed to respect.

ON EXPLORATION

  • Radius Gold Inc. released rock sampling results from its Amalia project in Chihuahua. A new discovery in the San Pedro area returned 13 m @ 2.51 g/t Au, 164 g/t Ag in a continuous chip sample (10 individual samples), while new sampling 50 m above and along strike the Guadalupe zone returned 8 m @ 0.21 g/t Au, 264 g/t Ag. At the Campamento zone a 500×700 m zone of intense silicification and brecciation with massive and stockwork veining is interpreted as high level mineralization. On lower parts of the property sulfide rich fault breccias are hosted in andesites, where mineralization is narrower and higher grade. Epithermal Au-Ag mineralization occurs along 3.5 Km on strike and 600 m of vertical interval. Drill permitting documentation has been submitted.
  • Gainey Capital Corp. signed a LOI to acquire the 9,200 hectares La Minita Cu-Au-Ag property in Sinaloa. A series of NW trending shears host porphyry mineralization associated with intermediate and felsic dikes, which are more than 300 m in length and up to 10 m in width. Fine grained sericitic alteration, silicification, quartz stockworks and copper sulfides (bornite, chalcopyrite) as disseminations and veins occur in prospect pits by gambusinos.

ON MINING

  • Great Panther Silver Ltd. announced that SEMARNAT granted all permits for construction and operation of the new phase II tailings storage facility at its Topia mine in Durango.
  • Mexus Gold US informed that it has produced gold with the installed Merrill Crowe system at its Santa Elena mine in Sonora (not to mistake with First Majestic’s Santa Elena mine, also in Sonora). The Merrill Crowe system will continue to be tested until the end of the year, as mine site security is upgraded before full production begins.
  • Americas Silver Corp. announced that the San Rafael mine at the company’s Cosalá operations in Sinaloa is now in commercial production, as of December 19, 2017. Mine production is currently averaging 1,200 tonnes per day (tpd) and increasing.

ON FINANCING

  • Telson Resources Inc. entered into a loan facility and offtake agreement with Trafigura Mexico, S.A. de C.V., to sell 100% of the Pb-Zn concentrate produced at the Tahuehueto mine from January 2018 to December 2022.

  • Consolidated Zinc Ltd. announced that drilling on the Tres Amigos North zone intersected 5.60 m and 4.35 m respectively of massive sulfides. “Assays are pending but visual analysis shows mineralisation comprises banded textured massive sulphides with very fine to fine-grained pyrite overprinted by coarse-grained yellow to reddish sphalerite and minor galena associated with carbonates”. Results are pending.
  • Oceanus Resources Corp. completed the fall 2017 drill program which comprised 600 m of diamond drilling to define the strike and dip of the high-grade Caleigh vein and the low-grade alteration zone in the hanging wall. Assays for the last six holes are pending, and expected to be released in January 2018. Work during Q1 2018 is to focus in locating and defining other high-grade vein systems in the property, and begin to look for mineralization on the favorable El Tigre formation over a distance of 5 km.

ON DEALS AND CORPORATE ISSUES

  • Torex Gold Resources Inc. informed it has suspended the employment contracts of its workforce in Mexico, a direct result of an illegal blockade at its El Limon-Guajes mine in Guerrero. The blockade by the Los Mineros Union, “an outside union that wants to take over representation of the employees who already have a union. Since the blockade began, on November 3, 2017, the Company has continued to pay its workforce, except for the minority that have participated in the illegal blockade”. Torex has made a call to the relevant authorities to remove the illegal blockade, as they have committed to do, and restore the rule of law. The company is willing to work with the Union the employees select, but it is essential the illegal blockade is lifted to resume work after Christmas. The company stresses that “The risk of violent confrontation continues to escalate and we urge the authorities to restore law and order and diffuse the tensions, so that employees of the Company, contractors, and suppliers, can go back to work and provide for their families.”
  • Orex Minerals Inc. signed a non-binding agreement with Canasil Resources Inc. and Pan American Silver Corp. to advance exploration in the Sandra Escobar mining camp in Durango. Under the terms of the LOI (Letter of Intention) the Orex (55%)-Canasil (45%) JV is to grant Pan American a 10% interest in the Sandra property, with the opportunity for Pan American in the next four years to earn-in an additional 41% in the Sandra property by contributing US$5 M toward the operations of both properties, with US$2 M required during the first two years. If Pan American elects not to continue during the earn-in period, the initial 10% will revert back to the Orex-Cansil JV. If Pan American chooses to further advance the properties by completing a pre-feasibility study, it will retain a 60% interest and the Orex-Canasil JV 40%.
  • Gainey Capital Corp. signed a LOI with Asteria Mining Services S.A.P.I. de C.V. to acquire 100% of the 9,200 hectares La Minita Cu-Au-Ag property in Sinaloa.
