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.

Congress Mine property, located in Yavapai county, central Arizona, comprises 105.2 hectares (260

acres) of patented land and 200.2 hectares (494.8 acres) that were acquired by staking.

Casa Minerals

Inc. owns a 90% interest in the historic claims from 40 feet depth and beyond and an undivided 100% of

the staked ground.

A 1.5% Net Smelter Royalty is payable on production from the patented claims and

certain surface rights to depth of 12.2 metres (40 feet) are held by a third party.
