ON MEXICO ISSUE
- No relevant news.
ON EXPLORATION
- Tocvan Ventures Corp., reported surface exploration results from areas located over 6km north of Pilar´s Main Zone within its Pilar project in Sonora. Sampling returned very high-grade silver with gold values.. Two samples yielded 1,225 g/t Ag with 3.2 g/t Au and 744 g/t Ag with 0.2 g/t Au from sample material next to historical artisanal workings. One of the samples also show higher polymetallic association returning 0.42% Cu, 3.4% Zn, and over 20% Pb (assay over limit was reached).
- Aztec Minerals Corp., reported final results from the 2023 RC drilling from its Cervantes project. The RC drilling program consisted of 1,646m in 13 holes testing the California porphyry gold target. All drill holes intersected oxidized Au mineralization; the California target continues to be open; the California target now has an area of 1,000m by 300m drill demonstrated; and the California target was found to continue on strike to the east at least another 400m. The multi-element ICP results show good, positive relationships between Au, Cu, Bi, Ag, As, W and K (potassic alteration), negative relationships with Mo, Sb and Ca. The multi-element grades support the potential for an Au-Cu porphyry deposit at depth.

The Diamante property exhibits characteristics of “epithermal low to intermediate sulfidation Ag-Au (Pb-Zn), high sulfidation Au-Cu, and potential transition zones within and peripheral to porphyry style Au-Cu mineralization”.
- Kootenay Silver Inc. announced results from three additional drill holes at its Columba project in Chihuahua. The drill program envisages 3,000 m on 12 to 15 holes to extend known mineralization on the “D” vein target area. Highlighted core length intervals comprise 29 m @ 208 gpt Ag, 0.2% Pb, 0.5% Zn (including 9.67 m @ 510 gpt Ag, 0.2 gpt Au, 0.5% Pb, 1.0% Zn; which includes 2.37 m 1,142 gpt Ag, 0.1 gpt Au, 0.9% Pb, 2.5% Zn), 10.1 m @ 152 gpt Ag, 0.2% Pb, 0.4% Zn; 3.1 m @ 308 gpt Ag, 0.1% Pb, 0.3% Zn (including 1.56 m @ 532 gpt Ag, 0.2% Pb, 0.4% Zn). “Columba hosts an extensive network of intermediate-style epithermal quartz, carbonate +/- barite veins aligned into two broadly cross-cutting orientations. Fieldwork to date has identified numerous mineralized structures across the project measuring up to 4 kilometres in length.”
ON MINING
- Luca Mining Corp. announced results from its optimization program at the Campo Morado mine in Guerrero. A bulk concentrate is being produced with greater than 70% Cu recovery, up from the historical 35-40% recovery range. “Overall zinc recovery is expected to increase from 76% to 86% and the final concentrate grade increases from 46% to 56% zinc over the next 12 months…. Ausenco have conducted a range of laboratory testing, initially of zinc circuit feed samples, to study the potential for improved zinc circuit stage recoveries. With a series of changes to reagents and other operational parameters in flotation in the plant, overall zinc recovery increased from 75% to 82% and the final concentrate grade from 45% to 51% zinc”. Additional work is being conducted to produce clean and higher-grade Cu and Pb concentrates.
- Golden Minerals Co. has begun producing gold-bearing pyrite flotation concentrate from its Velardeña properties in Durango. “The Company is processing material that has been stockpiled at Velardeña since the mines last operated in 2015”. Recent favorable market terms for Au bearing pyrite/arsenopyrite concentrate are now economic to process and sell.
- Impact Silver Corp. announced its financial and operating results for the third quarter 2023. At Zacualpan, in Estado de Mexico, throughput was 37.2 K tonnes @ 162 gpt Ag. At Plomosas, in Chihuahua, Impact has completed the final steps to get back online the 200 tpd zinc mine. “Exploration potential at Plomosas is exceptional with only 600m of the 6-kilometre-long structure assessed”. The company invested $3.8 M in exploration expenditures and mining assets, with a cash position at quarter-end of $8.9 M and working capital of $8.7 M.
- Bear Creek Mining Corp. reported results for Q3 2023. At the Mercedes mine in Sonora, 123.5 K tonnes were mined @ 2.79 gpt Au, with 126.2 K tonnes processed averaging 2.40 gpt Au, recovering 93.4% Au to produce 9,155 Oz Au, 33.7 K Oz Ag. During the period the company entered into a restructuring agreement with Equinox Gold Corp. to convert a $26 M current liability into a non-current obligation by issuing a convertible promissory note at a competitive interest rate. A second restructuring agreement was signed with Sandstorm Gold Ltd. to reduce near-term Au and Ag stream delivery obligations and refinance and extend debt. A C$9.5 M private placement was completed also during the period. Mining methods have been changed to sub-level caving at the San Martin deposit and sub-level stoping at the Marianas deposit. Average mining costs have decreased from $80.84 per tonne mined to $68.37 during the year (15% decrease). The Mercedes structural trend has contributed with “over 580,000 ounces of gold to the mine’s historical production since 2011”. Production from the San Martin deposit increased from 400 tpd to almost 600 tpd during Q3 and is expected to reach 800 tpd during Q4 2023.

One of these high-grade intercepts is 97 m below the last mine development, while another high-grade replacement zone was identified. An unusual tourmaline breccia pipe was intersected, returning 1.77 m @ 4.07 gpt Au. “Drill results from the Quebradillas mine have enhanced our understanding and confidence that the La Parrilla Mine can be brought back online. In 2024, Silver Storm will proceed with technical studies targeting the re-establishment of mining operations in 2025.”
- Sonoran Desert Corp. filed the NI 43-101 compliant technical report on the Cuatro Hermanos project in Sonora. The Mineoro Explorations LLC produced report states mineralization is of Porphyry Cu-Mo style associated to a porphyry intrusive complex hosted in an andesitic volcanic sequence, with Cu-Mo mineralization forming subvertical orebodies related to magmatic breccias and possibly tabular bodies of more than 3 Km along strike. Modelling suggests the Main and West zones might be connected, and that deeper drilling is needed. Recommended activities include relogging of core and RC drilling chips from the 2007-2008 campaigns, check assays on 10% of the pulps, drilling the West zone at 100 m spacing, deeper drilling, twinning of some holes, RC drilling and column leach test on the South Conglomerates (Exotic Cu target), begin metallurgical testing of oxides and sulfides, tie surface access agreements and commence permitting for drilling.
ON DEALS AND CORPORATE ISSUES
- Coeur Mining Inc. signed a purchase agreement with Fresnillo PLC to acquire mining concessions adjacent to the Palmarejo complex in Chihuahua. The concessions comprise 2,833 ha, including the southeast extension of the Independencia and Nacion deposits, currently being mined at the Palmarejo property, and to the northeast a concession that surrounds “multiple targets containing mineralization and historic resources that were added through the 2015 acquisition of Paramount Gold and Silver. The terms of the transaction include a $10 M payment upon closing, an additional $10 M one year after closing and an additional $5 M two years after closing. The concessions will be subject to a royalty payment of $25 per Oz for each new Oz AuEq of resource discovered between 450 K and 2 M Oz AuEq.
