Casa, in 2022, commenced drilling to confirm a substantial gold "resource" of 400,000 to 500,000 tons (365,000 to 455,000 tonnes) grading 0.3 opt (9.33 g/t) that were reported in 1989 by Echo Bay Mines, the most recent explorer/operator. Republic Goldfields Inc., dba Malartic Hygrade U.S. Inc., subsequently reported production of 28,500 ounces gold from 125,000 tonnes (i.e. 0.23 opt). Over the course of its history, the Congress gold mine has produced about 400,000 to 500,000 ounces of gold from underground workings and once supported a full ore processing plant, complete with a small frontier-style town. After more than 100 years of intermittent activity, the mine last operated in 1992. The above-quoted numbers cannot be verified and have not been audited by a Qualified Person, and do not conform to current NI 43-101 standards and should not be relied upon in any evaluation of the Congress Gold Mine.

Gold occurs with vein quartz and in strongly silicified granite.
