Vancouver, British Columbia – March 25, 2025 – Leocor Mining Inc. (the “Company” or “Leocor”) (CSE: LECR, OTCQB: LECRF; Frankfurt: LGO0) (formerly Leocor Gold Inc.), a junior resource company focussed on the exploration and development of precious metals  projects in Eastern Canada, is pleased to announce that recent drill program at the Baie Verte project (“The Project”), a 2,002-ha contiguous gold-copper exploration package located on the north central coast of the island of Newfoundland in the province of Newfoundland and Labrador, Canada, has been completed.

Crews from Rally Drilling and Resourceful Geoscience Solutions have demobilized from the Project site on March 18^th after completing 27 drillholes totalling 3040.5m at the project’s base metal and gold prospects, Copper Creek and Dorset, respectively.

Drilling at the Copper Creek claims comprised 21 diamond drillholes totalling 2308.5 meters. 18 of the 21 Copper Creek drillholes encountered mineralization interpreted to be chalcopyrite over various lengths and in various visually estimated abundances. Previously disclosed Copper Creek highlights included:

• 9m to 46.2m (2.3m length) in hole 25-CC-014 containing a visually estimated modal abundance of banded chalcopyrite of 15% with pyrite in visually estimated modal abundances of 10%.
• 20m to 33.4m (13.4m drilled length) in hole 25-CC-012 containing blebby chalcopyrite in a visually estimated modal abundance of 1%.
• 6m to 138m (4.4m drilled length) in hole 25-CC-007 containing blebby chalcopyrite in a visually estimated modal abundance of 3%.

Holes 25-CC-015, -017, -019 and -020 intersected intervals of semi-massive pyrite over drilled lengths between 0.2m and 2.2m.  Figure 1 below, first released on March 3^rd, illustrates an interval of semi-massive pyrite mineralization observed in drill hole 25-CC-017.

The Company awaits assay results from 1671 samples from Copper Creek drilling.

Drilling at the Dorset gold prospect comprised six holes totalling 732 meters. Highlights of the Dorset drilling include intersecting a pyrite mineralized quartz vein with a drilled length of 1.1 meters in hole 25-DR-005 (Figure 2).

Figure 2: Hole 25-DR-005 32.0m to 49.1m, featuring a 1.1m long pyrite mineralized quartz vein from 36.5m to 37.6m downhole, outlined in red.

The Company awaits assay results from 655 samples of drill core from Dorset drillholes.

It is important to note that these are preliminary observations, and the true grade and thickness of the mineralization will only be determined once assay results are received. Samples of mineralized intervals are being prepared for geochemical analysis by SGS, a Standards Council of Canada (SCC) accredited laboratory. As of March 21, 2025, the laboratory confirmed 205 samples from Copper Creek are currently being processed, with an estimated date of completion within the next four weeks.
