Corcel Exploration Inc. (CSE: CRCL) (OTCQB: CRLEF) (the “Company” or “Corcel“) is pleased to provide a summary of the results of historical drilling conducted at the Yuma King mine, within the 100%-owned Yuma King Project in west-central Arizona. The Yuma King Project hosts the historical Yuma King mine that produced over 7,917 tonnes from underground workings between 1940 and 1963, producing 461,686 lbs Cu (average grade of 2.65%), 2,700 lbs Pb, 261 oz Au (average grade 0.94 g/t), and 5,371 oz Ag (average grade 19.4 g/t) (Rasmussen and Keith, 2024).
The most recent historical exploration programs focused on the Yuma King mine and included two drilling campaigns conducted in 2006 from five drill sites (YK01, YK02, YK03, YK04, and YK06) and 19 drill holes, and 2011 (AV-1 and AV-21) (Figure 1). Over 3,900 metres have been drilled from 21 drill holes between the two programs. The 2006 drilling intersected significant oxidized copper skarn mineralization in the Yuma King mine area, successfully extending the mineralization up-dip and along strike from the mine workings (Figure 2). Skarn mineralization was intersected in all drill holes located near the mine with thicknesses ranging from 9.14m to 36.6m and with copper values between 0.2 to 4.8%, Au values between 0.06 and 4.5 g/t, Ag values between below detection limit and 1,510 g/t, and Mo values between 20 and 500 ppm.
Highlighted intervals2 from the historical drilling include:
- 45.4 metres of 0.78% Cu, 0.53 g/t Au, and 6.3 g/t Ag from 4.6 m in hole YK01-A
- 36.9 metres of 0.62% Cu, 0.53 g/t Au, and 3.8 g/t Ag from 5.2 m in hole YK01-B
- 24.4 metres of 0.74% Cu, 0.48 g/t Au, and 4.4 g/t Ag from 5.9 m in hole YK01-C
- 30.8 metres of 0.55% Cu, 0.56 g/t Au, and 4.7 g/t Ag from 6.7 m in hole YK01-D3
- 27.4 metres of 0.14% Cu, 0.08 g/t Au, and 1.1 g/t Ag from 344.4 m in hole AV-1, a ~400m down-dip step-out from the historical Yuma King mine
Holes YK01-A, YK01-B, YK01-C, and YK01-D were located up-dip of the Yuma King mine, and hole AV-1, collared approximately 365m northeast of the historical mine workings, intersected the down-dip extension of the mineralization (Figure 3), demonstrating at least 500m of down-dip skarn potential. Dolomite, dolomite skarn, and marble skarn are the primary hosts of the copper and gold mineralization and are cut by moderately Cu-Au-Mo mineralized Jurassic porphyritic intrusions.

“The historical drilling at Yuma King demonstrates the strength and continuity of the copper-gold skarn system, with multiple holes intersecting broad zones of mineralization near the historical mine and extending over 760 metres to the east,” commented CEO, Jon Ward. “Importantly, the work completed to date provides us with a strong foundation as we refine our upcoming drill program that will focus on testing extensions of the known skarn horizons with a potential strike length of 1.6 km, as well as related porphyry Cu-Au-Mo mineralization. The next phase of exploration at Yuma King will further unlock the broader potential for our shareholders.”

The purpose of the planned upcoming drill program will be to confirm and extend the copper and gold mineralization in and around the Yuma King Mine area. Post-mineral deformation including fold repetition of the mineralized skarn-hosting units, and structural cover of these units, may have hidden compelling exploration targets. Some of these are highlighted by recent drone magnetic surveys which have the potential to image magnetic skarn mineralization (Figure 4; Corcel Exploration New Release July 28, 2025). Recent surface sampling has outlined Au in soil anomalies (Corcel Exploration News Release May 13, 2025) which point to further strike potential in the Yuma King mine area (Figures 1, 2, and 4).

Future Exploration Plans
Corcel is advancing preparations for its maiden drill program and is also planning for additional geophysical surveys, specifically Induced Polarization (IP), to further delineate subsurface targets in the nearby Three Musketeers area. In parallel, the team will initiate hyperspectral imaging to enhance alteration mapping and vectoring, while continuing the 3D integration of geological, geochemical, and geophysical datasets. These efforts are designed to refine the geological understanding of the project and generate additional strong drill targets.
