Leocor Mining Begins Summer Exploration Program at the Baie Verte Copper-Gold Project, Newfoundland

(TheNewswire)

Vancouver, BritishColumbia – TheNewswire - June 04, 2025 - Leocor Mining Inc. (the “ Company ” or “ Leocor ”) (CSE: LECR, OTCQB: LECRF;Frankfurt: LGO0) (formerly Leocor Gold Inc.), a juniorresource company focussed on the exploration and development ofprecious metals  projects in Eastern Canada, is pleased to announce it hascommenced a soil sampling program at the Baie Verte project (“TheProject”) , a 2,002-ha contiguous gold-copperexploration package located on the north central coast of the islandof Newfoundland in the province of Newfoundland and Labrador, Canada,has been completed.

Crews from Resourceful Geoscience Solutions havearrived to complete follow-up soil sampling on The Project's Five MileBrook gold prospect. In 2021, the company undertook a preliminary soilsampling survey, which returned several anomalous results (See Companynews release dated May 19, 2022), including two samples from onesurvey line that yielded 132 ppb Au and 163 ppb Au. This same surveyline also concluded with an anomalous result of 85 ppb Au.

The 2021 survey collected B horizon soil at 25m spacedstations along 125m spaced parallel lines. The current follow-upsurvey aims to confirm the anomalism detected in 2021 throughconfirmatory duplicate sampling of sites that returned resultsexceeding 100 ppb Au, to extend the line to the northwest where the2021 survey terminated with an 85 ppb Au sample, and to infill thesurvey line spacing adjacent to this survey line with new survey lineswhich close the sample line spacing to 60m.

Results from the recently completed 27-hole, 3040-meterwinter drill program are expected shortly and the Company is pleasedto report it has already begun preliminary planning for follow-upfield activities.  All assay results will be released once received,reviewed and verified.

As reported in the March 25, 2025, Company newsrelease, the completed drill program comprised 21 diamond drillholestotalling 2308.5 meters at the Copper Creek claims within the largerBaie Verte project ground. 18 of the 21 Copper Creek drillholesencountered chalcopyrite mineralization over various lengths and invarious visually estimated abundances. Previously disclosed CopperCreek highlights included:

• 43.9m to 46.2m (2.3m length) in hole 25-CC-014containing a visually estimated modal abundance of banded chalcopyriteof 15% with pyrite in visually estimated modal abundances of10%.

• 20m to 33.4m (13.4m drilled length) in hole 25-CC-012 containingblebby chalcopyrite in a visually estimated modal abundance of 1%.

• 133.6m to 138m (4.4m drilled length) in hole 25-CC-007 containingblebby chalcopyrite in a visually estimated modal abundance of 3%.

Holes 25-CC-015, -017, -019 and -020 intersectedintervals of semi-massive pyrite over drilled lengths between 0.2m and2.2m.  Figure 1 below, first released on March 3, 2025, illustrates an interval of semi-massive pyritemineralization observed in drill hole 25-CC-017.

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

Drilling at the Dorset gold prospect comprised sixholes totalling 732 meters. Highlights of the Dorset drilling includeintersecting a pyrite mineralized quartz vein with a drilled length of1.1 meters in hole 25-DR-005 (Figure 2).

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

It is important to note that these are preliminaryobservations, and the true grade and thickness of the mineralizationwill only be determined once assay results are received. Samples ofmineralized intervals are being prepared for geochemical analysis bySGS, a Standards Council of Canada (SCC) accredited laboratory.
