ON EXPLORATION

• Almadex Minerals Ltd. provided an update on its exploration plays and plans for 2023, including information on its Mexican properties. At the San Pedro project in Jalisco, a high-sulfidation acid sulphate lithocap alteration and sulfide bearing breccia zones with elevated base and precious metals were tested with four holes. The bests intervals comprise 4.51 m @ 0.03 gpt Au, 657 gpt Ag; 1.3 m @ 846 gpt Ag; 2.9 m @ 7.45 gpt Au. Mapping and sampling of the Victoria project in Puebla on epithermal silver rich veins was conducted for a planned 2023 drill program. In March the company will conduct a surface mapping program on the Yago project, located in Nayarit.
• Minaurum Gold Inc. provided an update in underground rehabilitation work at the Promontorio mine on its Alamos project in Sonora. “Our underground rehabilitation has now accessed 600 metres of an estimated 1.2 kilometres of workings …. The workings continue to be in good and stable condition. Backfill material continues to be removed and stockpiled outside the mine entrance for future processing”. Assays from 37 backfill material returned seven samples over 1 gpt Au (5.74 gpt peak), ten samples over 150 gpt Ag (308 gpt Ag peak), eleven samples above 0.5% Cu (1.57% peak), 20 samples over 1.0% Pb (3.91% peak) and 26 samples over 1.0% Zn (8.19% peak).

ON MINING

• Argonaut Gold Inc. released operating and financing results for Q4 2022, without disclosing figures on its Mexican operations. At the end of the period the company held $73.3 M in cash and cash equivalents. Its Mexican operations include the San Agustin mine in Durango and the La Colorada mine in Sonora, and the Cerro del Gallo project in Guanajuato.
• Aura Minerals Inc. filed its audited financial statements and management discussion for the year 2022, without disclosing the figures by project. For 2023 the company expects to produce between 101 K to 116 K Oz AuEq at cash cost $685 to $788 per Oz AuEq and an AISC of $898 to 1,033 per Oz AuEq at the Aranzazu mine in Zacatecas. “Exploration is expected to focus on the geological potential of new mineralized zones, such as Cabrestante, El Cobre and Limestone Bridge with 20,000 m of drilling planned to 2023. All targets are near mine, some of which have been drilled in the past and indicated skarn mineralization but requiring follow up drilling”.
• Endeavour Silver Corp. announced financial and operating results for year 2022. The company that operates the Guanceví mine in Durango and the Bolañitos mine in Guanajuato produced 5.96 M Oz Ag, 37,548 Oz Au (or 9.0 M Oz AgEq) at cash cost $10.65 and an AISC of $19.97 per Oz Ag. By the end of the period the company had $83.4 M in cash and $93.6 M in working capital. Development activities continue at Terronera, in Jalisco, and an initial mineral resource estimate was published for the Pitarrila project in Durango.

ON DEALS AND CORPORATE ISSUES             

• Riverside Resources Inc. announced the signing an option agreement to acquire 100% interest in the Union mine, within the Union District in Sonora. Riverside paid $170 K and can earn-in the 100% interest by making a second payment of $100 K anytime within 60 months of signing the agreement, after which a 1.25% NSR is retained the underlying owner, same that can be bought in 0.25% increments of NSR for $250 K each at any time. “.
