ON MEXICO ISSUES

  • The first declarations of liberties (or open ground for staking) for the year was released on February 19th. The 95 concessions on several states will be open for staking at 10:00 am, 30 days after the date of publication on the official gazette (Diario Oficial de la Federación).

ON EXPLORATION

  • One World Lithium Inc. signed a contract to drill 4,200 m of reverse circulation holes on its Salar del Diablo property in Baja California. The program includes 12 holes varying between 150 and 500 m of depth to test three geophysical highly conductive zones and two geochemical surface sampling anomalies.
  • Prize Mining Corp. presented drilling results from its Manto Negro project in Coahuila. Mineralized intercepts include 4.4 m @ 1.02% Cu, 28 gpt Ag; 3.55 m @ 1.69% Cu, 28 gpt Ag at Manto Negro; 4.10 m @ 0.88% Cu, 49 gpt; 3.40 m @ 1.58% Cu, 122 gpt Ag; 4.05 m @ 0.82% Cu, 55 gpt Ag; 1.0 m @ 1.43% Cu, 126 gpt Ag; 2.90 m @ 0.72% Cu, 24 gpt Ag; 2.05 m @ 0.76% Cu, 33 gpt Ag; 6.05 m @ 1.29% Cu, 77 gpt Ag; 1.05 m @ 3.23% Cu, 135 gpt Ag; 3.80 m @ 1.62% Cu, 143 gpt Ag at Pilar Grande; 6.75 m @ 0.75% Cu, 9 gpt Ag; 1.20 m @ 0.71% Cu, 13 gpt Ag at La Cuchilla, and 1.10 m @ 1.21% Cu, 26 gpt Ag; 1.50 m @ 1.24% Cu, 102 gpt Ag at El Pilon.

  • McEwen Mining Inc. Reported fourth quarter and full year 2018 results, including information on its Mexican operations. At El Gallo in Sinaloa, 5,632 Oz AuEq were produced on the quarter, and 39,105 on the year, at cash cost $733 and AISC $771. El Gallo 2019 production guidance is 13,000 gold ounces at cash costs and AISC per GEO of $875 and $915, respectively. These ounces are derived from residual heap leaching activities that are ongoing and will continue for several years.
  • Torex Gold Resources Inc. presented its yearly production report 2018. During the last quarter Torex delivered 96,316 Oz Au, reaching 353,947 Oz Au produced on the year. This was achieved by the mining of 32.6 M tonnes, or 93,214 tonnes per day (tpd), of which 4.33 Mt @ 2.69 gpt Au were ore. The plant processed 4.15 Mt at a rate of 13,011 tpd @ 2.97 gpt during the year, with a recovery of 85% Au, a cash cost of $646 per Oz Au and AISC of $964 per Oz Au.

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.

ON EXPLORATION

  • 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”.

ON MINING

ON MEXICO ISSUES

  • According to CAMIMEX (in a note from opportimes) copper production in Mexico has been stable. During 2017 the world´s copper production was 19.7 M tonnes, a 2% decrease from 2016. Mexico produced 742 K tonnes of copper in 2017, against 766 K tonnes produced in 2016, a 3.1% decrement. Sonora produces over 84% of the country’s total, with Zacatecas and San Luis Potosi following suit. Coming additions to production include El Boleo in Baja California Sur, which is to double its production to 28.5 tonnes; Media Luna in Guerrero is to add 21 K tonnes in 2022 and El Pilar project in Sonora could add 36 K tonnes in 2020.

ON EXPLORATION

  • Radius Gold Inc. completed drilling at its Amalia project in Chihuahua. Nine holes, for a total of 1,909 m were diamond drilled in a program funded by Pan American Silver under a JV. The Campamento, Guadalupe, San Pedro and Dulces Nombres targets were tested across a strike length of 1.8 Km “following the trace of a large regional fault and associated surficial epithermal gold and silver mineralization”. Results pending.
  • Prize Mining Corp. released results from the first four holes at the Manto Negro stratiform copper project in Coahuila. Core length drill intersections comprise 4.40 m @ 1.02% Cu, 28 g/t Ag; 3.55 m @ 1.69% Cu, 28 g/t Ag at El Granizo; 4.10 m @ 0.88% Cu, 49 g/t Ag; 3.40 m @ 1.58% Cu, 122 g/t Ag at El Pilar Grande. At El Rincon, 1.6 Km north from El Pilar Grande, rock channel sampling averaged 3.41 m @ 2.13% Cu, 63 g/t Ag.
  • Silver Viper Minerals Corp. released the first batch of analyses from its initial drilling program at La Virginia project, in Sonora. Results have been received for five of the eight holes from which samples were submitted, with relevant intervals comprising: 9.70 m @ 1.20 g/t Au, 58 g/t Ag (2.03 g/t AuEq), including 2.72 m @ 3.34 g/t Au, 133 g/t Ag (5.24 g/t AuEq); 12.6 m @ 1.04 g/t Au, 79 g/t Ag (2.17 g/t AuEq), including 3.85 m @ 1.88 g/t Au, 152 g/t Ag (4.05 g/t AuEq); 0.7 m @ 2.25 g/t Au, 49 g/t Ag (2.95 g/t AuEq); 8.50 m @ 1.26 g/t Au, 55 g/t Ag (2.05 g/t AuEq) including 1.89 m @ 2.43 g/t Au, 81 g/t Ag (3.58 g/t AuEq); 0.94 m @ 0.96 g/t Au, 49 g/t Ag (1.66 g/t AuEq). The reported holes were collared on Las Huatas zone, with the first two testing parallel veins to the main trend, whereas the last three tested the previously identified main trend, generally intercepting mineralization at expected depths, widths and grades. “The intercepts are characteristic of previous hits on the project, where gold and silver bearing quartz veining/stockwork/breccia fill is often hosted in close proximity to the fractured contact between andesites of the lower volcanic succession and pre-mineral dacite dykes. Mineralization is hosted by both lithologies with the intervals often exhibiting strong silica overprint”.
  • Riverside Resources Inc. informed rock sampling and mapping defined four new targets at its Cecilia project in Sonora. The recent work was conducted on a 50 square km area, checking on previous soil sampling results. The Casa de Piedra, Los Llanos, Cruz and Cruz II targets were outlined, forming structural corridors up to 2 km long of quartz veins (locally banded, locally bearing calcite), anastomosing quartz veins, veins and quartz stockworks that can be up to 30 m in width and locally up 100 m in width. Alteration assemblages in these zones include sericite, silica, kaolinite and buddingtonite. All these areas display anomalous gold values, of up to 2.6 g/t Au.
  • Golden Minerals Co. released rock sampling results from its recently optioned Navegantes project in Chihuahua. Navegantes covers two vein systems, Navegantes and San Pedro‐San Francisco) as well as a number of smaller subsidiary veins, with mineralization occurring as iron oxides within quartz veins ranging up to 2 m in width and 800 m in length.
