Corcel Exploration Reports Historical Drill Results Ahead of Planned Phase I Drill Program

Vancouver, British Columbia--(Newsfile Corp. - October 7, 2025) - 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.
