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.

ON MEXICO ISSUES

  • The president of the Commission on Mining and Regional Development, Geovanna del Carmen Bañuelos de la Torre, said that it is necessary to create a new legal framework to standardize the safety, health and protect workers and the environment. She also recognized that the actual distribution of the Mining Fund lacks rigor on its application, and that a reform proposal has been formulated.

ON EXPLORATION

  • Sable Resources Ltd. summarized its 2018 exploration program, including information from its projects in Mexico. During 2018’s second quarter Sable completed 2,420 m in 12 drill holes at the Margarita project in Chihuahua, testing epithermal veins in Eocene-Oligocene volcanic rocks. “The project is defined by 5 veins; Margarita, El Caido, Juliana, Faviana, and Marie. All exploration drilling by Sable up to this point was executed along 750 m strike of the Margarita Vein”. Results for the first round of drilling include close to surface high-grade intersections like: 252 g/t AgEq over 11.3 m;  462 g/t AgEq over 4.25 m and larger low-grade halos as: 36 g/t AgEq over 21.35 m and 50 g/t AgEq over 44 m. “A second round of drilling planned to start in mid-January includes 1360m in 9 holes to extend the drilling for 1.5km along the known surface trace of the Margarita vein and to close the drilling grid to approximately 250m space. In addition, 1750m will be drilled in 13 exploration holes that will test the other veins”. Sable received title for 12 mining concessions covering 38,396 ha in Chihuahua, all covering stream sediment and rock sample anomalous areas, including the drill ready Vinata vein system located NE of the Margarita project. The company also holds projects in Canada, Peru and Argentina.
  • San Marco Resources Inc. confirmed the existence of a porphyry Cu-Mo-Au system at its Espiritu project in Sonora. The work done confirmed a multi-stage system with an alteration foot-print at least 2.5 Km x 1.2 Km and that the best Cu mineralization is surface and drill core samples is in rocks with potassic alteration and a quartz-chalcopyrite-pyrite stockwork. There are indications that copper mineralization might be preserved at depth within the shallower part of the porphyry system(s). Future work is expected to include magnetic and ZTEM surveys in advance of possible drilling at the project.
  • Kottenay Silver Inc. reported that new assay results from outcropping quartz veins support the potential for the discovery of a high-grade silver deposit at its Columba project in Chihuahua. The veins have strike lengths of 200 m to 2 km, and thicknesses from 0.5 to 6 m. In the latest field campaign 50 channel and 90 grab samples were collected on eight of the ten veins in the property. “Highlights include 33 samples, between lengths of 0.70 and 2.0 meters, returning silver values ranging between 30 gpt to 397 gpt and 55 samples returning grades >10 gpt”. Contiguous channel samples averaged 4.9 m @ 198 gpt Ag; 3.5 m @ 276 gpt Ag; 2.2 m @ 330 gpt Ag; 6.6 m @ 182 gpt. The next steps are additional mapping and surface sampling to prioritize drill targets and obtain drill permits.
