Leocor Mining Drills Semi-Massive Sulphide Mineralization at Copper Creek

(TheNewswire)

Vancouver, BritishColumbia – TheNewswire - March 03, 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 ofgold-copper projects in Eastern Canada, is pleased t o provide an update on the ongoingdrill program at the Baie Verte project, a 2,002-ha contiguousexploration package located on the north central coast of the islandof Newfoundland in the province of Newfoundland and Labrador,Canada.

Crews completed the Copper Creek drill drillingcampaign on Feb 27th after successfully drilling 21 diamond drillholes. Drilling equipment is now remobilizing the company’s Dorsetproject to explore gold mineralization targets defined by anomaloussurface geochemistry, ground magnetometer survey interpretation andthe company’s previous trenching results reported ( news release dated February 20 th 2025 ).

Following the previously reported occurrences ofbelieved chalcopyrite mineralization in 10 of the programs first 13holes, the company is pleased to report that at least 15 of thecampaign’s 21 holes encountered mineralization interpreted to bechalcopyrite over various lengths and in various visually estimatedabundances with 3 holes intersecting intervals of semi-massive pyriteover drilled lengths between 0.2m and 2.2m. Highlights are describedin further detail below.

Hole 25-CC-012 intersected intermittent intervals ofinterpreted chalcopyrite in association with other sulphide mineralsbetween 10m and 80m downhole. Mineralized intervals range between 0.3mand 3.1m in drilled length and contain interpreted chalcopyrite invisually estimated model abundances of 0.1% (trace) to 2%. Thehole’s most significant interval with respect to chalcopyriteaccumulation, 23.6m to 26.0m (2.4m length) contained a visuallyestimated modal abundance of wispy chalcopyrite of 2%.

Hole 25-CC-013 intersected intermittent intervals ofinterpreted chalcopyrite in association with other sulphide mineralsbetween 11.5m and 80m downhole. Mineralized intervals range between0.8m to 12m in drilled length and contain interpreted chalcopyrite invisually estimated modal abundances of 0.1% (trace) to 1%. Thehole’s most significant interval, with respect to chalcopyriteaccumulation, 40.3m to 50.7m (10.4m length) contained blebbychalcopyrite a visually estimated modal abundance of 1%.

Hole 25-CC-014 intersected intermittent intervals ofinterpreted chalcopyrite in association with other sulphide mineralsbetween 4.0m and 88.0m downhole. Mineralized intervals range between0.3m to 7.4m in drilled length and contain interpreted chalcopyrite in visually estimated modal abundances of 0.1%(trace) to 15%. The hole’s most significant interval, with respectto chalcopyrite accumulation, 43.9m to 46.2m (2.3m length) contained avisually estimated modal abundance of banded chalcopyrite of 15% andoccurs with pyrite in visually estimated modal abundances of10%.

Hole 25-CC-015 intersected intermittent intervals ofinterpreted chalcopyrite in association with other sulphide mineralsbetween 15.7m and 119.2m downhole. Mineralized intervals range between0.3m to 19.8m in drilled length and contain interpreted chalcopyritein visually estimated modal abundances of 0.1% (trace) to1.0%. Thehole’s most significant interval, with respect to chalcopyriteaccumulation, 64.2m to 78.7m (14.5m length) contained a visuallyestimated modal abundance of blebby chalcopyrite of 1.0.

Hole 25-CC-017 encountered 3 intervals of semi-massiveto massive pyrite between 52.3m and m downhole. These intervals allcontain semi-massive pyrite in visually estimated modal abundances of30-75% with 0.1%(trace) to 0.5% Chalcopyrite.

Similarly, hole 25-CC-018 encountered two intervals ofsemi-massive pyrite 60% pyrite from 122.7m to 123m and 80% pyrite from124m to 124.3m, both intervals 0.3m in drilled length, and hole25-CC-019 encountered semi-massive pyrite in visually estimated modalabundances of 40% between 58.2m and 59m downhole, 0.8m drilledlength.

Hole 25-CC-016, also intersected mineralizationbelieved to be chalcopyrite but not in estimated abundances or drilledlengths deemed to be significant at this time.

Additional information pertaining to holes 25-CC-020and 25-CC-021 will be provided after detailed logging.

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, an accredited laboratory, and the Company expects to receiveresults within four weeks.

Drill Hole Targeting

Multiple drill holes at Copper Creek recently targetedareas of known mineralization identified in 2022 Rab drilling as wellas previously mapped structures displaying hydrothermal alteration andanomalous base and precious metal geochemistry from soil and rocksampling.  At the Dorset claim, drill targets are concentrated inareas where the Company intersected significant gold results duringits 2022 RAB drilling campaign detailed the company’s September 19, 2023 newsrelease . The drill program is being conducted under the supervision of David Murray,P. Geo, president of Resourceful Geosciences. The Company will providean update early next week.

The Dorset project is prospective for additional goldoccurrences and the 2025 program will be designed to test some of thepriority zones within a prominent 1 x 2 km gold-in-soil anomalydelineated by Leocor in 2022.
