ON MEXICO ISSUES

  • Almaden Minerals Ltd. informed that “a lower court in Puebla State has ruled that Mexico’s mineral title system is unconstitutional because consultation is not required before the granting of mineral title………..This ruling can be appealed by both the Government of Mexico and Almaden. The Company believes that this lawsuit is part of a broad effort by special interest groups to change the mining law and there are other similar actions active across Mexico”. Almaden stated that no communities within the company’s current mining concessions on its Ixtaca project in Puebla are party to this lawsuit.
  • Fresnillo PLC. Presented its 2018 annual report. It is here recommended to all interested in the mining business in Mexico to take a look to the report (http://www.fresnilloplc.com/media/412015/fres-30452-annual-report-2018-web.pdf), especially on the section “Managing our risks”. In the said section, the risks of participating in the industry in Mexico are assessed, including those of metal prices, potential actions by the government, access to land, security, public perception against mining, safety, union relations, exploration, project performance, cyber security, environmental incidents and human resources. Although the report had in mind Fresnillo’s particular situation as one of the largest Mexican mining conglomerates, many parts of the evaluation concern risks that affect all mining enterprises in the country.

ON EXPLORATION

  • Aloro Mining Corp., commenced a 3.6km road construction and building of 12 permitted drill pads at its Los Venados project in Sonora. “The road construction will open up new exposures for sampling in mineralized areas and structure that were previously undercover”.
  • San Marco Resources, commenced a drilling program at its Chunibas project in Sonora where they have a JV agreement with Antofagasta plc. The drilling program will consists of initial 1,500m comprised in six holes with the goal of testing down dip and along strike high-grade Cu-Ag mineralized mantos hosted in volcanic rocks in different stratigraphic levels. The manto-type mineralization has been identified along a corridor of 1.7km long and at least 300m wide.
  • Sonoro Metals Corp., reported results from the initial 13 drill holes from its Cerro Caliche project in Sonora. Significant intersections are: Hole SCR-002 with 27.43m of 0.6 g/t Au and 7 g/t Ag; Hole SCR-003 with 30.48m of 0.5 g/t Au and 8 g/t Ag; Hole SCR-004 with 39.62m of 0.9 g/t Au and 9 g/t Ag, including 6.09m of 2.9 g/t Au and 20 g/t Ag; Hole SCR-005 with 10.67m of 0.7 g/t Au and 21 g/t Ag, and 10.67m of 0.6 g/t Au and 1 g/t Ag; Hole SCR-006 with 10.67m of 1.2 g/t Au and 21 g/t Ag, including 6.1m of 2 g/t Au and 26 g/t Ag; Hole SCR-007 with 22.86m of 0.9 g/t Au and 13 g/t Ag, including 4.57m of 2.2 g/t Au and 20 g/t Ag; and SCR-008 with 36.58m of 0.5 g/t Au and 4 g/t Ag. “The drilling has further confirmed that mineralization in the Los Japoneses zone remains open in all directions, including at depth.”
  • Minaurum Gold Inc., discovered two new vein zones at its Alamos Silver project in Sonora: the San Jose vein, a NNE trend structure hosted in a fault zone which can be traced for at least 3km long, and the Santa Rosa vein, a stringer-quartz veinlets structural zone that runs for at least 300m along strike. The discovery of the new veins was through its ongoing district-scale reconnaissance program. Sampling on the San Jose vein returned grades ranging from anomalous up to 1,995 g/t Ag, 2.5% Cu, and 1.9% Zn, while sampling on the Santa Rosa vein only retuned anomalous values.
  • Discovery Metals Corp., completed a 40 line-km ground magnetic survey at its Monclova project in Coahuila to cover three targets: Real Viejo with 23 lines spaced 50m apart, Corrales with 17 lines spaced 100m apart, and Soledad with 12 lines spaced 50m apart. “Results of the Real Viejo survey highlight a linear magnetic high parallel to the mapped mineralized and altered zone along the southern boundary of the Monclova intrusive complex centered on the Project. This suggests continuity of the alteration and/or mineralization along the contact and provides support for the holes planned to test this zone. Interestingly, similar magnetic high zones occur across the neighboring Corrales target. Both linear magnetic highs as well as linear lows are highlighted by the survey and represent prospective targets on the Project. Results at the northern Soledad grid also highlight similar geometries”.

ON RESOURCES AND DEVELOPMENT

  • Kootenay Silver Inc., designed a program of 15,000m of drilling over 62 holes aimed to expand resources along the extensions of its La Cigarra deposit in Chihuahua. The drilling program will be conducted on four target areas where the company believes there is untested potential to increase resources. “The plan would entail primarily exploration step out drilling of known mineralization and some infill drilling of the successful La Borracha program earlier this year”. “The four areas Kootenay plans to target are the La Borracha high grade (the mineralized trend located 1,000 meters northwest from the northern boundary of the Resource), the La Borracha Connection (connecting La Borracha with the San Gregorio area of the Resource), Gap (a very under drilled area between the main San Gregorio and Las Carolinas zones that currently comprise the Resource) and the Carolinas Extension (the strike extension of the Resource to the southeast)”.
  • Hecla Mining Company, released in-fill drilling results for its San Sebastian mine in Durango. The in-fill drilling was conducted in the central portion of the polymetallic zone along the Francine Vein. Additionally, exploration core drilling was also conducted toward shallower oxide mineralization along the West and East Francine vein areas, the recently discovered South Vein, and at the Esperanza Vein target area. At the Francine vein, the in-fill drilling program intersected high grade mineralization. Highlights include 1.37m of 591 g/t Ag, 4.8% Cu, 16% Pb and 13.5% Zn and 2.25m of 227 g/t Ag, 1.8% Cu, 3.5% Pb, and 6% Zn. The drilling also intercepted narrow but high-grade mineralization along the East Francine vein on new zones of vein-hosted oxide mineralization. Significant intersections are 1.46m of 485 g/t Ag and 0.3 g/t Au, and 2.83m of 299 g/t Ag and 2.2 g/t Au. Mineralization in this area is defined over 1,200 feet along strike and 800 feet down-dip and this new zone could represent an important new source of oxide mineralization. At the West Francine vein, the drilling program encountered also narrow intervals of high grade. Highlights include 0.64m of 1,791 g/t Ag and 0.62 g/t Au. Mineralization in this area is open laterally and at depth. Follow-up, offset drilling is in progress. At the Esperanza vein, exploration drilling commenced but results are pending. Reconnaissance RC drilling discovered a new blind vein under soil cover in the Saladillo Valley. This new vein, referred as the South vein, intercepted significant mineralized intervals such as 2.83m of 392 g/t Ag and 2.5 g/t Au, 2.86m of 187 g/t Ag and 0.93 g/t Au, and 2.86m of 174 g/t Ag and 1.24 g/t Au. Drilling for the remainder of the year will continue to focus on expanding resources and evaluate near-surface oxide mineralization at the West Francine Vein, South Vein, and Esperanza Vein areas.

ON MINING

  • Hecla Mining Co. reported second quarter 2018 results, including figures from its San Sebastian project in Durango, where 559,647 Oz Ag, 3,872 Oz Au were produced during the period. The mill operated at an average of 415 tpd (tons per day). Cash cost was $9.79 per Ag Oz and AISC $17.15 per Ag Oz, reflecting the higher cost of transitioning from open pit to underground mining. “A reduction in per ounce costs is expected in the second half of the year as underground production continues to ramp up”.
  • Torex Gold Inc. reported its financial results for the second quarter 2018. Mine production at Limon-Guajes totaled 7.15 Mt (tonnes), averaging 78,629 tpd (tonnes per day) of which 1.28 Mt was ore processed at 11,140 tpd. Mined ore averaged 2.45 g/t Au and processed ore 2.86 g/t Au, for the production of 78,796 Oz Au, with 87% Au recovery in the period and cash cost of $680 per Oz Au and AISC of $1,017 per Oz Au. Cash held at the end of the period was $117.9 M.

During the quarter Golden reported final drill results from the Santa Maria project (Chihuahua) 2017-2018 drill program and announced the preparation of an updated technical report and preliminary economic assessment (PEA). In August 2018, Golden entered into a non-binding letter of intent with The Electrum Group LLC upon which Electrum is to purchase Golden’s remaining interest in the Celaya property in Guanajuato for a payment of $3 M. Cash and cash equivalents stood at $2.5 M at the end of the period.
  • Argonaut Gold Inc. released financial results for the second quarter 2018. During the period the company produced 38,441 GEOs (Gold equivalent ounces) at cash cost $704 per Oz Au and AISC of $832 per Oz Au. At El Castillo, in Durango, 2.22 Mt (tonnes) of waste, and 2.15 Mt (tonnes) were moved, with 2.12 Mt ore @ 0.37 g/t Au crushed to the pads to produce 10,079 Oz Au, 8,111 Oz Ag at cash cost $992 per Au Oz. At San Agustin in Durango, 618 Kt of waste, 1.85 Mt of ore were moved, with 1.88 Mt of ore @ 0.36 g/t Au crushed to the pads to produce 15,528 Oz Au, 55,781 Oz Ag. At La Colorada, in Sonora, 1.81 Mt of waste, 1.06 Mt of ore were moved (32 K tpd), with 1.14 Mt of ore @ 0.36 g/t Au crushed to leach pads to produce 11,503 Oz Au, 29,360 Oz Ag at cash cost $833. “The Company expects the third quarter 2018 will see lower production due to the lower grades stacked on the leach pad during the second quarter 2018 and also expects higher costs during the third quarter 2018 associated with drilling, blasting and hauling costs for normal state operations”.” While the Company’s explosives permit has been reinstated at La Colorada, the legal action brought against the Secretary of National Defense and the Municipality of La Colorada continues through the Judiciary court process”.
  • Alio Gold Inc. reported second quarter 2018 results. The San Francisco mine in Sonora produced 14,466 Oz Au, 7,661 Oz Ag at by-product cash cost $950 per Oz Au, while AISC was $1,172 per Oz Au. The Company is reducing stripping and focuses mining on more profitable ounces to maintain cash neutral operations. As a result of the reduced stripping, the ”production guidance of 90,000 to 100,000 ounces of gold for 2018 will not be met.” At Ana Paula in Guerrero, all development work including the construction of the underground decline, the completion of the feasibility study and further exploration have been temporarily suspended as result of the recent decline in the gold price.
  • Odyssey Marine Exploration Inc. reported second quarter 2018 results. “Odyssey holds a controlling interest in Oceanica Resources, S. de R.L., and ExO, a subsidiary of Oceanica. ExO controls exclusive 50-year mining permits in an area in Mexican waters that contains a large amount of phosphate mineralized material”.” On March 21, 2018, the 11-judge panel of the Superior Court of the Federal Court of Administrative Justice in Mexico ruled unanimously in favor of ExO, nullifying the original denial of the environmental permit application.“ (Don Diego, Pacific Ocean cost of Baja California Sur)
