ON MEXICO ISSUES

  • Majors of 23 of the 38 Municipalities of Coahuila state are called to receive the Mining Fund. An urgent request was made to 23 Majors of Municipalities benefited with resources from the Mining Fund in order to make this benefit effective. To achieve this objective, the projects in which the resources will be applied must be presented.
  • The Director of the Mining Fund of the Secretariat of Economy, María del Socorro Gómez Leyja, indicated that the Technical Committee of the Federal Mining Fund allocated resources for 16 projects in the states of Chihuahua (MXP $ 18.6M), Coahuila (MXP $ 3.1M), Durango (MXP $ 7.6M) and Guerrero (MXP $ 4.6M).
  • MXP $18.6M from the Mining Fund was allocated to Chihuahua. The Municipalities of Aquiles Serdán and Ocampo in the state of Chihuahua, will have resources from the Mining Fund that will be used for paving, dome, well and water network, thanks to the approval by the Technical Committee of the Mining Fund.
  • The President of Mexico, Andres Manuel López Obrador (AMLO) was requested by workers of Minera Cosalá to end the illegal strike that affects that mine site. The same workers, said to AMLO that the leader of its Union affiliated with the CTM, negotiated the collective work contract with the company Minera Cosalá SA de CV, and determined that the operation was normal and there were no irregularities on the part of the company. However, workers close to the senator of the Morena party and mining leader Napoleón Gómez Urrutia, asked the company for salaries higher than normal. They mentioned that the mine has been working since 2003 and they have a safe job for at least six more years, in excellent working conditions and that their only desire is to work, regardless of which Union won the collective agreement.
  • Oaxaca´s mining potential, according to specialists, government and private capital, could be profiled as one of the most important in Mexico, to generating jobs and strengthening the regional economy of indigenous communities. Currently the state has not been explored outside the mining districts and known mineralized areas, but contains promising areas for Au, Ag, Cu, Pb, Zn, Sb, and non-metallic minerals such as micas, zeolites, marble, travertine, and granite among others. Data from some civil organizations indicate that Oaxaca’s mining production represents 0.72% of the total national value, with Ag first, second Au and third Pb.
  • Ricardo Sierra Oteiza, official spokesperson of the Esperanza project in Morelos State, said that through the new model of social end environmentally responsible mining, the company Esperanza Silver de Mexico will comply 100% with Mexican standards not only with the community of Tetlama, but throughout the Municipality of Temixco, Morelos. In addition, he stressed that there will be an investment of over USD $400M in the 10 years that the company plans to carry out work in the state.
  • In recent years, Mexico has registered the suspension of dozens of mining projects, whose assets have been victims of price volatility, licensing obstacles, adverse political factors, and community opposition. BNamericas accounts for 59 Mexican projects suspended in its database, compared to 95 active projects. Of the 11 suspended projects for which financial information is available, combined capital expenditure totals USD $ 2.4B.This compares to 42 active projects whose combined capital expenditure amounts to USD $ 14.2B. The greater projections for Au and Ag, along with political changes at the state level, have improved the prospects for the resumption of some of the suspended projects. However, the depressed prices of Cu and Zn and not minor problems with obtaining permits and other legal aspects continue to put important obstacles on others. Some of the largest suspended projects are La Verde in Michoacan, Sierra Mojada in Coahuila, Angangueo in Michoacan, Ixtaca in Puebla, Ana Paula in Guerrero and Esperanza in Morelos. Other suspended projects are Monterde in Sonora, Caballo Blanco in Veracruz, San Antonio, Baja California Sur, and La Bolsa in Sonora.

ON EXPLORATION

  • Colibri Resource Corporation, announced the commencement of its maiden drill program at its Evelyn project in Sonora. The initial 5-diamond holes drilling program will be focused on two mineralized corridors named Cerro Rojo and El Sahuaro and is expected to be completed in three weeks.
  • Silver Viper Minerals Corp., provided drilling results from its El Rubi project in Sonora. All holes encountered mineralized zones, with several significant interceptions in hole LV20-217 with 4.45 g/t Au and 401 g/t Ag (10.18 g/t AuEq or 713 g/t AgEq) over a true width of 4.56m, including 15.55 g/t Au and 1,436 g/t Ag (36.06 g/t AuEq or 2,524 g/t AgEq) over a true width of 1.14m; 1.79 g/t Au and 91 g/t Ag (3.1 g/t AuEq or 217 g/t AgEq) over a true width of 7.41m, including 7.49 g/t Au and 586 g/t Ag (15.86 g/t AuEq or 1,110 g/t AgEq) over a true width of 0.57m; and 2.05 g/t Au and 46 g/t Ag (2.70 g/t AuEq or 189 g/t AgEq) over a true width of 6.27m, including 8.44 g/t Au and 201 g/t Ag (11.3 g/t AuEq or 791 g/t AgEq) over a true width of 1.14m. Hole LV20-218 also intersected several mineralized zones with 5.82 g/t Au and 530 g/t Ag (13.39 g/t AuEq or 937 g/t AgEq) over a true width of 1.89m, including 14.4 g/t Au and 1,253 g/t Ag (32.3 g/t AuEq or 2,261 g/t AgEq) over a true width of 0.63m; 9.15 g/t Au and 569 g/t Ag (17.28 g/t AuEq or 1,210 g/t AgEq) over a true width of 5.04m, including 22.63 g/t Au and 1,431 g/t Ag (43.08 g/t AuEq or 3,015 g/t AgEq) over a true width of 1.89m. The El Rubi mineralized structure has now been intercepted on seven sections for a total 300m of strike extent.
  • Chesapeake Gold Corp., provided an update on the exploration program at its Crisy and San Javier prospects, located 15Km south and 12 km southeast respectively from its Metates project in Durango. These both projects cover several zones of Au-Ag mineralization along regional, deep-seated northwest-trending fault zones, associated with intermediate intrusive rocks that have altered the enclosing sedimentary rocks over an area more than 15 km in diameter. At Crisy, Chesapeake competed 4 trenches totaling 350m in length and returned 1.1 g/t Au and 10 g/t Ag over 57m; 1 g/t Au and 10 g7t Ag over 11m; 1.1 g/t Au and 33 g/t Ag over 12m; and 2.2  g/t Au and 29 g/t Ag over 7m. In addition, an initial 15km IP survey is underway over the trenched area at Crisy and preliminary results correlate well with the Au-Ag mineralization and suggest that the outcropping quartz bx zone extend to over 200m depth. It also indicates that the anomaly is continues along strike and remains open. The IP survey also defined a large NW-SE trending high chargeability anomaly about 200m to the SW of the bulldozer trenching. The IP survey indicates a more than 500m long by 500m wide on which limited sampling has returned 1.2 g/t Au over 4m wide, and 1 g/t Au and 13 g/t Ag over 5m wide. Four Km to the NW of the area of bulldozer trenching, multiple quartz structures within a corridor over 800m long by 200ms wide and with 150m of vertical extent were identified returning 1 g/t Au over 9m wide; 0.8 g/t Au over 12m; and 3.1 g/t Au and 10 g(/t Ag over 1.3m wide. Regional exploration has now identified several distinct target areas hosting quartz veins, bx and local stockwork along the 7 kilometer long hydrothermal system at Crisy. At San Javier, the company identified a 1.2km long, high-grade Au-Ag quartz vein structures over 300m in elevation. Channel sampling on these structures  returned encouraging results as 9.6 g/t Au and 143 g/t Ag over 2.8m; 3.3 g/t Au and 391 g/t Ag over 1m; 2.3 g/t Au and 18 g/t Ag over 1.4m; and 2.1 g/t Au and 113 g/t Ag over 1m. Trenching and IP survey is being carried out on San Javier to test the potential for disseminated Au hosted in highly altered intrusive rocks.
  • GoGold Resources Inc., presented drill results from nine holes collared at its Los Ricos project in Jalisco. Significant drill intersections were encountered in hole LRGG-20-100 with 1.51 g/t Au and 204 g/t Ag (4.23 g/t AuEq or 317 g/t AgEq) over 17.3m, including 6.56 g/t AuEq or 492 g/t AgEq over 6.9m; hole LRGG-20-98 with 1.78 g/t Au and 319 g/t Ag (452 g/t AgEq) over 7.5m; and hole LRGG-20-93 with 1.27 g/t Au and 113 g/t Ag (2.78 g/t AuEq or 208 g/t AgEq) over 19m. GoGold is undertaking two drilling and exploration projects at its Los Ricos property: the South Project began in March 2019 and includes the ‘Main’ area, which is focused on drilling around a number of historical mines including El Abra, El Troce, San Juan, and Rascadero.
