ON MEXICO ISSUES
- The Secretariat of Economy decentralized and moved the Undersecretariat of Mining to Chihuahua. Francisco Quiroja, the recently appointed Undersecretary of Mining, inaugurated in Chihuahua city the headquarter of the federal dependence and exposed that is key to promote an active industrial politics that foster the innovation, diversification and inclusion of the Mexican mining and metallurgy sectors. To reach the strategy planned , the Undersecretary of Mining will lean on the General Coordination of Mines, dependence in charge of regulating the sector, on the General Coordination of the Mining Development, to promote the development of the mining sector, on the Mexican Geological Survey, to support and push the competitiveness in exploration, on FIFOMI, to increase the financing and structure projects subject to credits, and on the Mining Fund to make sure the social viability of the different projects and of the validations of the same ones.
- The Undersecretary of Mining discarded to harden rules for mining industry. The Undersecretary of Mining (Francisco Quiroga) pointed out that the new government doesn’t look for to carry out drastic changes in the sector, canceling concessions or increasing the production royalties paid for mining companies. “The companies have rights and none right will be harmed, neither that of the communities neither that of the companies”. Francisco Quiroga affirmed that, for the time being, his efforts are centered in simplifying steps, to promote new projects and to impel the exploration in the sector. He also is analyzing changes to the formula of distribution of the Mining Fund.
- Aztec Minerals Corp., announced the completion of a helicopter-based airborne magnetic, radiometric , and VLF survey covering the entire 3,694 hectares with 100m spaced lines of its Cervantes project in Sonora. “Preliminary results show an extensive magnetic high under the California target extending and broadening towards the north. Other targets such as Purisima and Jacobo have either low to very high magnetic response respectively, suggesting that there is more than one phase of porphyry intrusions on the property. A large and interesting northwest-southeast oriented magnetic high was detected on the northwest side of the survey and corresponds to a newly identified area of extensive gossan oxide and pyrrhotite-pyrite- chalcopyrite-arsenopyrite mineralization in hornfels and sediments intruded by feldspar-quartz porphyry dykes. The pyrrhotite indicates a reduced copper-gold system and likely contributes to the magnetic high”. Aztec also reported high gold recoveries by cyanide leach analysis of 5 drill holes. Gold recoveries include 87% Au and 45% Ag over 98m in hole 18CER007, 84% Au and 54% Ag over 106m in hole 18CER006, and 84% Au and 49% Ag over 93.5m in hole 18CER003.
- San Marco Resources Inc., completed a drilling program funded by Antofagasta plc, on its Chunibas project in Sonora. 1,640m of core in seven holes were drilled to confirm down-dip and along strike alteration and mineralization observed on surface along a 1.2km long NW-SE mineralized corridor and a 400m long NE-SW perpendicular mineralized corridor. San Marco reported that all holes intersected several intervals with visible fine grained disseminations and cavity fillings of bornite, chalcocite, and traces of chalcopyrite. Assays results are pending and will be released once the company makes its analysis and interpretation.
- Mexus Gold US, released results of two holes drilled at the Julio area within its Santa Elena project in Sonora. Holes 4 and 5 averaged 0.8 g/t Au over 3 m and 2 m intercepts with a 1 m section of 1.4 g/t Au. Assay results are pending from holes 6 to 9 to complete the evaluation of the initial drill program on this target area.
- Minaurum Gold Inc., announced the mobilization of a second drill rig to its Alamos Silver project in Sonora to accelerate the testing of new veins identified recently. Minaurum also announced rock sampling results and the discovery of the 1.2km long monzonite-hosted Salvia vein zone. Highlights of the rock sampling include 1m of 1,150 g/t Ag, 2m of 1.03% Cu, 1.2m of 3,240 g/t Ag, and 1.50m of 747 g/t Ag.
- Colibri Resources Corporation, provided a review of its exploration activities during 2018 of its projects in Sonora. Colibri drilled 2,900m in 27 holes at its El Pilar project, extending the length of the known mineralized gold deposit 52% and confirmed many of the historical drill results from the previous operator. Drilling highlights of the 2018 program are 9m of 8.2 g/t Au, including 1.5m of 33.4 g/t Au; 28.5m of 0.57 g/t Au, including 3m of 4.24 g/t Au; 40.5m of 0.73 g/t Au, including 3m of 5.37 g/t Au; and 61.5m of 0.75 g/t Au, including 1.5m of 17.3 g/t Au. El Pilar and Evelyn projects have been reviewed by several companies for potential JV opportunities, however none agreement has been made at this time. The company also added two gold exploration projects named El Mesquite and Jackie by the purchase of Yaque Minerals, a private exploration company. El Mesquite contains a 600m long by 300m wide mineralized zone with values up to 3.41 g/t Au. Geophysical surveys have identified resistivity and chargeability anomalies with merits to be drill tested. Jackie is a grass root gold exploration project. An exploration campaign is expected to be carried out in 2019, which will consists of mapping, stream sediment sampling, chip sampling, and possibly a soil sample grid.
- Prize Mining Corporation, released drill results from the Pilar Grande target within its Manto Negro project in Coahuila. Significant intersections are in hole DDHDI-18-05 with 2.5m of 0.72% Cu and 46 g/t Ag, including 0.55m of 1.43% Cu and 126 g/t Ag, and 0.45m of 1.74% Cu and 87 g/t Ag; hole DDHDI18-05 with 2.15m of 0.79% Cu and 37 g/t Ag, and 2.90m of 0.72% Cu and 24 g/t Ag.
- Almadex Minerals Ltd., initiated a small “proof of concept” drill program at Gallo de Oro target within its Yago project in Nayarit where banded epithermal veins crop out at surface. At El Chato project in Puebla, Almadex has identified drill targets based on a defined IP chargeability anomaly beneath a zone of intense alteration interpreted to correspond with the upper portion of a buried porphyry system. Almadex geologists believe the El Chato has the same geological setting to that of Azucar Minerals Ltd´s El Cobre Cu-Au porphyry project in Veracruz.
- Azucar Minerals Ltd., announced drill results from the North Zone within its El Cobre project on Veracruz. Highlights drill results at the North Zone include hole EC-18-053 with 231.50m of 0.45 g/t Au and 0.17% Cu, including 132m of 0.68 g/t Au and 0.24% Cu, and 70.20m of 1.07 g/t Au and 0.35% Cu, and 33.20m of 1.54 g/t Au and 0.49% Cu; hole EC-18-055 with 245.50m of 0.39 g/t Au and 0.17% Cu, including 148.50m of 0.54 g/t Au and 0.22% Cu, and 59.05m of 0.87 g/t Au and 0.32% Cu, and 33.30m of 1.10 g/t Au and 0.39% Cu; and hole EC-18-058 with 248.90m of 0.39 g/t Au and 0.19% Cu, including 74.50m of 0.67 g/t Au and 0.33% Cu, and 21.90m of 1.22 g/t Au and 0.55% Cu. Based on the drill results, the geologists have interpreted that “the mineralization appears to trend in NE-SW direction, that a late-mineral and barren to weakly mineralized intrusive occurs in the middle of the North Zone but tops out about 400m below the current surface, and that the mineralization remains open to depth, on either side of the late intrusion, and along strike to the northeast”.
- Endeavour Silver Corp., provided an early review of its El Cubo mine plan in Guanajuato for 2019. The company plans to reduce the production rate in 2019 to approximately half its 1,500 tonnes per day, while continuing exploring for new reserves to extend the mine life.
