 ON MEXICO ISSUES

  • Mining Chamber of Mexico (CAMIMEX), demanded the authorities to act in the conflict between Peñasquito and a transport company called CAVA. The company declared that the illegal blockade which started more than a month ago, harms entire families and the productive chains of the region. CAMIMEX also stated that is essential that mining companies in the country can work without being subject to illegal pressures and, like any industry that develops in the country, their demands are met promptly through legal channels and attached to the rule of law. The company initiated the suspension of payments to employees and unionized workers, contractors, suppliers and communities. However, the company is willing to help unlock this situation that affects 20 thousand people who work directly or indirectly for the mine.
  • Mexico mining exploration, registered its lowest investment in 12 years. The mining exploration investment in Mexico during 2018 reached USD $383M, which represented a year-on-year decrease of 37.4% and its weakest level in the last 12 years, according to data from the Mining Chamber of Mexico (CAMIMEX).

ON EXPLORATION

  • Aloro Mining Corp., announced that soon it will resume drilling at its Los Venados project in Sonora. The drilling plan will consist of 1,200m in four holes and will be focused on the blind target discovered by hole LVRC-012 which intersected 32m of blind strong silicic alteration containing 1.72 g/t Au over 4.57m, interpreted as the margin of a concealed felsic dome.
  • Azure Minerals Limited, released drilling results from its Alacran project in Sonora, where its JV partner Minera Teck completed 21 holes phase 2 diamond drilling campaign for 10, 540m. 16 of the drill holes targeted porphyry-style copper mineralization at Cerro Alacrán prospect, while the remaining 5 holes targeted epithermal-style precious metal mineralization at Cerro San Simon and Cerro Colorado areas. This phase of drilling confirmed the existence of porphyry copper mineralization with broad zones of visible chalcopyrite intersected. Significant drill intersections include hole ALA-18-001 with 0.17% Cu over 118m; hole ALA18-003 with 0.25% over 131.7m; hole ALA-18-011 with 0.19% Cu over 137m; and hole ALA-18-014 with 0.21% over 177.3m.

This hole intersected 54.47 g/t Au over 16.5m, and is located in the North Hill Zone; a series of 9 consecutive assays including an intersection of 80.3 g/t Au, interpreted to correspond with hole Q-8b. This hole intersected 9.64 g/t Au over 13.5m; and another series of 6 consecutive assays including 0.54 g/t Au, 8.52 g/t Au, 20.66 g/t Au, 16.23 g/t Au, and 6.97 g/t Au, interpreted to correspond with hole P-9b located in the Main Zone, which encountered 10.16 g/t Au over 9m.
  • Silver Spruce Resources inc., completed field work at its Pino de Plata project in Chihuahua. The field program expanded areas of intrusive-related alteration and mineralization to > 50 hectares; confirmed that high silver grades are present on surface at El Terrero and Gossan areas; added three new vein targets at La Perla, Santa Clara and El Muro vein systems; and refined drill collar locations and orientations to optimize targeting. The company announced that eight targets were identified for drill testing: “gossans in the Gossan zone, skarn/replacements at Santa Elena, the Terrero mine target, the La Perla vein and associated alteration zone, the Santa Clara vein, the Theodora vein, the Sierpe veins and associated alteration, and the newly defined Muro vein.” The company holds a drill permit for 30 holes but only plans to drill 12 holes for an estimated of 2,000m during the phase 1.
  • Radius Gold Inc., provided an update of its ongoing drilling program at its Amelia project in Chihuahua. Radius has completed three drill holes proximal to hole AMDD19-010 which encountered 12.38 g/t Au and 309 g/t Ag over 34m of true width. Hole AMDD19-011 intersected 97m of “varying intensity quartz veins, stockwork veining and diorite dykes”; hole AMDD19-012 intersected a zone of 53m of “alteration including variable stockworks, silicification and hydrothermal breccias”; and hole AMDD19-013 intersected 17m of “moderate to strong silicification, tectonic breccia with micro vein stockworks and traces of fine sulphides”. Assays for these holes are pending.

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.

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”. GoGold produced 325.1 K Oz AgEq.

ON MEXICO ISSUES

  • CAMIMEX (Cámara Minera de México), in a response to El Financiero, expressed that any modification to the mining regulations has to take into account the wellbeing of the communities and its environment. The organization, of which leading companies like Peñoles, Grupo México and Minera Frisco are members, considers mining is one of the most supervised sectors in the country, with a modern and robust regulatory frame, following international standards, although areas of opportunity can always be identified.  “We have approached diverse authorities on the public administration and found openness to solve any pending issues and consolidate the international competitivity that benefits the country development”.

ON EXPLORATION

  • Orex Minerals Inc. contracted Geotech Ltd. To perform a VTEM (Versatile Time Domain Electromagnetic) airborne survey over its San Luis del Cordero project in Durango. Old mine workings and mineralized showings wrap around a Tertiary quartz-feldspar-porphyry intrusive. The helicopter-borne survey, with accompanying horizontal gradiometer and radiometric surveys, is to identify discrete conductive anomalies, as well as mapping lateral and vertical variations in resistivity. The airborne survey will be conducted over a grid at 100 m line-spacing for approximately 275 line-km, with measurements every 2-3 m along survey lines.
  • Prospero Silver Corp. has started phase 2 drilling at its Pachuca Se project in Hidalgo. Fortuna Silver Mines Inc. has an option to acquire up to a 70% interest in the 6,699 hectares project (24 km SE from Pachuca) by spending a total of US$8 M and completing a preliminary economic assessment (PEA), spending more than US$1 M in the first year. A six-hole, 4,200 m program started to test a number of potential drill targets. In a Fortuna funded program in early 2018, 1,800 m of drilling tested three distinct targets, intercepting what is interpreted to be the upper parts of a mineralized epithermal system.
  • Radius Gold Inc. staked a 9,600 ha property called the Rambler project, in Chihuahua, some 20 km NW from Radius’s Amalia project.
