MIAMI – – November 04, 2026 -- American Bitcoin Corp. (Nasdaq: ABTC) swung to a third-quarter 2026 net income of about $126 million from a net loss of about $57.2 million in Q2, and reported Adjusted EBITDA of about $221 million versus an Adjusted EBITDA loss of about $45.0 million in the prior quarter.

The company raised its Bitcoin holdings by about 425 BTC, or roughly 5%, to about 8,427 BTC as of September 30, 2026, from about 8,002 BTC on June 30. Satoshis Per Share rose about 5%, from about 10,989 to about 11,572. Management said the gains came without issuing shares through its ATM program and without buying Bitcoin during the quarter.

Global – October 31, 2026 -- Reserve grades at producing silver mines span from about 12.63 g/t Ag at Coeur Mining's Rochester in Nevada to roughly 867 g/t at Hecla's Keno Hill, which shows that no single threshold defines "high-grade" silver.

Fresnillo reported a 2024 silver ore grade of 468 g/t at Juanicipio, an underground operation in Mexico. Hecla's year-end 2025 Keno Hill reserves stood at 25.28 ounces of silver per ton. Rochester's 2025 proven and probable reserves come from a large-tonnage open-pit heap-leach operation.

Grade does not equal recovered metal, and mines sell only recovered metal

A tonne carrying 500 g/t contains five times the silver of a 100 g/t tonne before recovery losses. Mines sell recovered metal, however, not grade. A narrow, discontinuous or hard-to-reach zone can leave a striking assay with limited economic value. Dilution from waste rock can also cut the grade delivered to the plant.

Nevada – September 22, 2026 -- i-80 Gold Corp. has completed a feasibility study for its Granite Creek Underground project outlining initial proven and probable mineral reserves of 556,500 ounces of gold at 7.87 grams per tonne across 2.20 million tonnes.

Measured and indicated resources jump 229% versus March 2025 preliminary assessment

The updated mineral resource estimate shows measured and indicated resources rising to 3.73 million tonnes grading 7.17 g/t gold, containing 859,500 ounces, a 229% increase from the PEA published in March 2025. Inferred resources fell 38% to 0.89 million tonnes at 7.06 g/t gold (202,800 ounces) as infill drilling converted material into higher-confidence categories. The estimate incorporates roughly 36,470 meters of drilling from 164 core holes completed between 2023 and the end of 2025.
