Vancouver, British Columbia – TheNewswire - March 03, 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 gold-copper projects in Eastern Canada, is pleased t o provide an update on the ongoing drill program at the Baie Verte project, a 2,002-ha contiguous exploration package located on the north central coast of the island of Newfoundland in the province of Newfoundland and Labrador, Canada.

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

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

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

Hole 25-CC-013 intersected intermittent intervals of interpreted chalcopyrite in association with other sulphide minerals between 11.5m and 80m downhole. Mineralized intervals range between 0.8m to 12m in drilled length and contain interpreted chalcopyrite in visually estimated modal abundances of 0.1% (trace) to 1%. The hole’s most significant interval, with respect to chalcopyrite accumulation, 40.3m to 50.7m (10.4m length) contained blebby chalcopyrite a visually estimated modal abundance of 1%.

Hole 25-CC-014 intersected intermittent intervals of interpreted chalcopyrite in association with other sulphide minerals between 4.0m and 88.0m downhole. Mineralized intervals range between 0.3m 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 respect to chalcopyrite accumulation, 43.9m to 46.2m (2.3m length) contained a visually estimated modal abundance of banded chalcopyrite of 15% and occurs with pyrite in visually estimated modal abundances of 10%.

Hole 25-CC-015 intersected intermittent intervals of interpreted chalcopyrite in association with other sulphide minerals between 15.7m and 119.2m downhole. Mineralized intervals range between 0.3m to 19.8m in drilled length and contain interpreted chalcopyrite in visually estimated modal abundances of 0.1% (trace) to1.0%. The hole’s most significant interval, with respect to chalcopyrite accumulation, 64.2m to 78.7m (14.5m length) contained a visually estimated modal abundance of blebby chalcopyrite of 1.0.

Hole 25-CC-017 encountered 3 intervals of semi-massive to massive pyrite between 52.3m and m downhole. These intervals all contain semi-massive pyrite in visually estimated modal abundances of 30-75% with 0.1%(trace) to 0.5% Chalcopyrite.

Similarly, hole 25-CC-018 encountered two intervals of semi-massive pyrite 60% pyrite from 122.7m to 123m and 80% pyrite from 124m to 124.3m, both intervals 0.3m in drilled length, and hole 25-CC-019 encountered semi-massive pyrite in visually estimated modal abundances of 40% between 58.2m and 59m downhole, 0.8m drilled length.

Hole 25-CC-016, also intersected mineralization believed to be chalcopyrite but not in estimated abundances or drilled lengths deemed to be significant at this time.

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

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

Drill Hole Targeting

Multiple drill holes at Copper Creek recently targeted areas of known mineralization identified in 2022 Rab drilling as well as previously mapped structures displaying hydrothermal alteration and anomalous base and precious metal geochemistry from soil and rock sampling.  At the Dorset claim, drill targets are concentrated in areas where the Company intersected significant gold results during its 2022 RAB drilling campaign detailed the company’s September 19, 2023 news release . The drill program is being conducted under the supervision of David Murray, P. Geo, president of Resourceful Geosciences. The Company will provide an update early next week.

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