Leocor Mining Drills 28.5 g/t Au over 0.4m at Dorset Gold Project, Baie Verte, Newfoundland

(TheNewswire)

Vancouver, BritishColumbia – TheNewswire - August 6, 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 report final assayresults from its recently completed drill program at the Dorsetprospect, located within the Company’s 2,002-ha contiguous BaieVerte gold-copper exploration project.  The Baie Verte project (“TheProject”) is situated on the north centralcoast of the island of Newfoundland in the province of Newfoundlandand Labrador, Canada.

The complete geochemical results received from SGSCanada, support the results of previous exploration at the project andconfirm the presence of orogenic gold mineralization at Dorset.

Gold Highlights Include:

Drillhole 25-DR-001

• 0.5m of 3.25 g/t Au within 1.1m of1.61 g/t Au beginning at 42.5m downhole

• 0.3m of 1.07 g/t Au beginning 100.3m downhole

Drillhole 25-DR-005

• 0.6m of 1.13 g/t Au within 1.1m of 0.67g/t beginning 37.0m downhole

• 0.4m of 28.5 g/t Au beginning 76.9m downhole

Further significant results from the drilling programare presented in Table 1, and images of the 25-DR-005 highlights arepresented below in Figures 1 and 2.

The Dorset drill holes successfully followed up theCopper Creek drill program, the results of which were announced in theCompany’s News Release dated July 8, 2025.   These results

support preliminary interpretations that the claimsrepresent the stockwork feeder zone of a Volcanogenic Massive Sulphide(“VMS”) mineralizing system. In addition to stockwork chalcopyritemineralization the program identified additional hallmarks of VMSsystems including anomalous zinc mineralization and lenses of massiveand semi-massive pyrite.

Results reported July 8 include the following Copperhighlights:

• 3.6m of 1.49 % Cu Including 0.9m of3.22 % Cu within 6.1m of 0.99 % Cu inhole CC-25-001 beginning at 31.7m downhole

• 6.6m of 0.44 % Cu Including 0.6m of1.97 % Cu in hole CC-25-002 beginning at 15.2mdownhole

• 3.6m of 0.66 % Cu Including 1.8m of0.92 % Cu Within 6.0m of 0.45 % Cu inhole 25-CC-006 beginning at 19.0m downhole.

• 4.1m of 0.56 % Cu Including 1.4m of1.43 % Cu in hole 25-CC-014 beginning at 45.7mdownhole.

Zinc highlights include:

• 3.0m of 0.34 % Zn Including 1.0m of0.69% Zn in hole 25-CC-006 beginning at 47mdownhole.

“The overall results of the 2025 drill program at ourBaie Verte project proved fruitful,” said Alex Klenman, CEO ofLeocor Mining.  “We were able to confirm the presence of a VMSsystem in a maiden effort at Copper Creek.  The Dorset claimscontinue to generate positive gold values. We are immediately planningfollow up work to prepare for further drilling.  We’re pleased withthe results to date and are eager to continue development of the BaieVerte project,” continued Mr. Klenman.

Modelling work is underway to place these resultswithin the geological context of the project and the Company isplanning follow-up exploration activities to evaluate the potential ofthis mineral system.  Specifics of the next round of work will beannounced shortly.

Significance of These Results

The Baie Verte Peninsula hosts a well-documentedmineral endowment, including several significant gold occurrences andmines associated with the regional Baie Verte Lineament (BVL), Thisgeological setting is conducive to the development of epigenetic goldmineralization, which is supported by a strong correlation withiron-rich rock types. Similar mineralization is documented at nearbyprospects, including the past producing Goldenville and Nugget PondMines as well as currently producing Pine Cove and StogertiteDeposits. Gold associated with proximal VMS deposits in the region isalso interpreted to be epigenetic in origin Figure 3 below outlinesnotable mineral deposits within the Baie Verte Peninsula.

Dorset Drilling

At the end of March 2025, the company completed acampaign comprising six diamond drillholes totalling 732 meters atDorset. The program was designed to follow up on significant goldanomalism in field sampling, trenching, and historical drillholecampaigns which were originally focused on surficial alteration andoutcropping veins. The 2025 program represents the first diamonddrilling campaign undertaken at Dorset by Leocor. Drillhole Collarinformation is detailed in Table 1.

Laboratory Technical Note

Analytical services were provided by SGS Canada, whichis an independent, CALA-accredited analytical services firm registeredto ISO 17025 standard. A 3 rd party contractor was employed to half drillcore by sawing. This contractor transported core between the logging,sawing and Laboratory locations. Sample Preparation took place atSGS’ facility in Grand Falls-Windsor, Newfoundland and Labrador,analysis was conducted at SGS Burnaby British Columbia. Samples werecrushed to 75% passing 2 mm, riffle split 250 g and pulverized to 85%passing 75 microns. Au assays were conducted on 30g of pulverizedmaterial using the Fire Assay method with a 4-acid digestion.Multi-element analyses, including base metals, were conducted onpulverized material using the ICP method for 40 elements. Laboratoryover-limits analysis methods were applied as required. A systematicQAQC protocol was employed that includes systematic insertion in thesample stream of certified reference materials and blank samples, plusanalysis of duplicate pulp splits and ¼ core duplicates.
