Casa Minerals Inc. provided an update for its Congress Gold Mine project located near the town of Congress in the Martinez Mining District of Yavapai County, Arizona, and an update of planning. Casa is the owner of a 90% interest in the Congress Gold Mine property. The historic Congress mine produced approximately 500,000 ounces gold from the Congress and Niagara veins.

All production was from underground workings. The Congress Gold mine operated at intervals from 1880 to 1992. Casa purchased the property in 2021 and conducted due diligence, data compilation and field surveys, followed in 2022 by diamond drilling 10 drill holes with a total length 2,081 metres (6,828 feet).

The 2022 drill program was planned to confirm the accuracy and integrity of the gold and silver mineralization database. Additionally, the purpose of the drilling was to establish geological characteristics of mineralization and host rock formations and to confirm exploration potential in and near the former Congress Mine. Operations were conducted in accordance with Arizona mining regulations and the federal Mines Act of 1871 and OSHA.

Site management and drill core processing were supervised by a Registered Professional Geologist registered in the State of Arizona. Based on the available historic data, additional mineral rights adjoining the mine were acquired by staking and the property now comprises both patented and Lode Claims totaling 305.33 hectares (754.48 acres). Historic data collected from the MY zone (western extension of the Congress Gold Deposit) has demonstrated a major gold veining system that has yet to be drill tested.

The geological and mineralization models have been developed and an exploration plan is being finalized that upon completion will be announced. Casa is currently planning a 2024 program of drilling and exploration work on the property to advance the Congress Gold Mine project. Work will be directed to follow-up drilling in the areas of gold-bearing quartz veins and auriferous sheared zones in and near the Congress and Niagara veins, and to potentially rehabilitate parts of the past producing mine.

The Congress mine is a shear zone hosted gold-silver deposit: low sulphide gold quartz veins occupy complex structural zones in coarse-grained gneissic granodiorite and pegmatite of Precambrian age. Gold values occur in association with fine-grained pyrite and, frequently, other sulphide minerals. Most historic production was from the Congress and Niagara veins that are exposed on surface over more than 1060 m (3,500 ft) and 365 m (1200 ft).

Both veins trend northwesterly and dip moderately to the north and were variously mined to several hundred metres from surface. Several other gold-bearing veins are referred to in archival documents but have not been investigated.
