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 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.

ON MEXICO ISSUES

  • The Mining Sub Secretariat head, Francisco Quiroga, informed the Mexican government is reviewing five thousand concessions in process of cancellation, as well as another five thousand in process of liberation, acknowledging a big and growing backlog.

ON EXPLORATION

  • Sable Resources Ltd. completed a leach test on core from the first phase drilling at its Margarita project in Chihuahua. The purpose was to investigate the response of three samples (684, 341, 149 gpt Ag) to silver leaching with cyanide in a bottle roll test. The two higher grade samples had a recovery of 70 and 71 percent Ag after 48 hours, while the lower grade sample had a recovery of 37 percent on the same time lapse. The second stage drilling at Margarita initiated in January, consisting of a minimum of 19 holes for a total of 3000 m, to test extensions and infill of the Margarita vein and the Marie, Juliana, Fabiana and El Caido veins. Six holes have been completed, with a best vein intercept of 12.4 m starting at 30.9 m. Sable received title for the Manzana II application, reducing the size to 39,396 hectares in 11 concessions. Vinata is a drill-ready low-intermediate sulfidation project within these concessions, in which a series of quartz veins outcrop along a strike length of about 1,150 m in volcanic rocks. “The system consists of multiple sub-parallel veins and stockwork zones over a width of between 15m and 170m. Individual veins vary in width from <1m up to about 12 m><1 m up to about 12 m”.
  • Aloro Mining Corp. completed 12 RC holes for a total of 1,747 m at its Los Venados project in Sonora. The drill program was designed to test a felsic dome complex NW of the Estrella pit, at the Mulatos mine. The thickest intercept of mineralization was 18 m @ 0.2 gpt Au. Other relevant intervals comprise 3.05 m @ 1.45 gpt, 4.57 m @ 1.72 gpt. The style of mineralization of one of the holes, like the coarse vuggy nature with crystalline quartz, octahedral pyrite, and tetrahedrite is deemed as very significant, and resembling the high-grade part of the nearby Mulatos deposit.
  • Gainey Capital Corp. reported first-pass sampling on its newly optioned Las Margarita project in Durango confirmed a 1,500-1600 m strike length for the main vein system. Preliminary work consisting of 42 samples resulted in 21 with over 1 gpt, with 11 of those assaying more than 5 gpt Au, peaking at 40.0 gpt Au.

ON MINING

  • United States Antimony Corp. has dismantled and trucked equipment from its Reynosa pant (Tamaulipas) to other USAC operations in Mexico and the United States. A lot of equipment, tools and materials were transported to the Madero smelter in Coahuila. The Madero plant received seven truckloads of Wadley (San Luis Potosi) direct shipping ore with a total of 128 K pounds of contained Sb. The assembly of the cyanide leach plant at the Puerto Blanco mill in Guanajuato is progressing. “Production from the caustic leach plant at Madero to process the flotation concentrates has resulted in close to a 100% recovery of the gold and silver”. Estimated Sb production for January is 156.6 K Lb antimony.
  • GoGold Resources Inc. reported a net income of $8.2 M for the last quarter of 2018. The previously announced sale of the 2% net smelter royalty was closed. “The closing of the sale of the royalty concludes the Corporation’s involvement with the Santa Gertrudis project which was initially acquired in 2014. Net consideration on the sale of assets associated with the Santa Gertrudis project was $88.6 million, less costs of $24.5 million resulting in a pre-tax gain of $64.1 million over the life of the project”.

ON EXPLORATION

  • Millrock Resources Inc., and its JV partner Centerra Gold Inc., reported drilling results from its La Navidad project in Sonora. The drilling program funded by Centerra consisted of 1,844m in eight holes and was focused on the northwestern portion of the project. Four holes were collared at El Tigre prospect where Au had been detected by soil sampling near of some historic mine workings. These holes tested IP anomalies and NW trending high-angle structures that appear to control mineralization at surface. Four other holes were collared at El Chupadero to test decalcification and jasperoid alteration pointed to the possibility of an intrusion-related gold deposit. Drilling results were generally disappointing just returning weakly anomalous Au values. Millrock has received notification from Centerra that it is terminating the option to JV agreements on La Navidad and El Picacho projects in Sonora.
  • Silver One Resources Inc., announced that a 1,000m drilling program will initiate by mid-February 2019 on its Peñasco Quemado project in Sonora.
