St. Augustine Gold and Copper is the little Toronto‑listed company behind the King‑king project in Davao de Oro, Philippines. The project covers 184 mining claims and contains a monster resource: a 2013 preliminary economic assessment valued it at US$1.78 billion (after‑tax) with a 24 % internal rate of return and a 2.4‑year payback using copper at US$3/lb and gold at US$1 250/oz.
Northern Dynasty’s Pebble project in Alaska’s Bristol Bay region isn’t just big — it’s biblical. The proposed open‑pit mine hosts a measured and indicated copper resource of 6.5 billion metric tons and another 4.5 billion tons inferred . Molybdenum, gold and silver resources add 1.26 million t, 53.82 million oz and 249.3 million oz respectively . Company management calls it “one of the greatest stores of mineral wealth ever discovered” — and they aren’t exaggerating.
Generation Mining is advancing the Marathon copper‑palladium project in Northwestern Ontario. The property spans 21 873 hectares across 46 leases and 933 claim cells and hosts a total measured and indicated resource of around 1.09 billion pounds of copper from 244 million tons at 0.2 % grade. A March 2025 feasibility study gave the project an after‑tax net present value of US$1.07 billion with a 27.6 % internal rate of return and a 1.9‑year payback.
Meridian Mining is developing the Cabaçal copper‑gold project in Brazil’s Mato Grosso state. A pre‑feasibility study released in March 2025 pegged the operation’s post‑tax net present value at US$984 million with an internal rate of return of 61 % and a payback period of just 17 months. The planned 10.6‑year mine is expected to produce 169 647 metric tons of copper and benefits from measured and indicated resources totalling 204 470 metric tons of contained copper from 51.43 million tons of ore grading 0.4 %.
West Red Lake Gold Mines (WRLG) is a junior miner with a simple plan: revive the historic Madsen mine and explore its 47‑sq‑km land package in Ontario’s famous Red Lake district. The Madsen underground mine produced about 2 million ounces of high‑grade gold between 1936 and 1971 , and the surrounding district has yielded more than 30 million ounces . According to a January 2025 BMO report, WRLG is the only single‑asset company launching production in a tier‑one jurisdiction this year. Talk about a rare bird!
Sigma Lithium is already one of the world’s lowest‑cost producers of carbon‑neutral lithium concentrate, operating its first Greentech plant in Brazil . But management isn’t content with status quo. They are building a second Greentech industrial plant that will double capacity and help feed the electric‑vehicle battery supply chain.
