Leocor Mining Drills 3.6m of 1.49 %Cu, Including 0.9m of 3.22 %Cu within 6.1m of 0.99 %Cu, at Copper Creek

VMS Mineralized System Confirmed 

Vancouver, British Columbia – TheNewswire - July 8, 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 report final assay results from its recently completed maiden drilling program at the Copper Creek prospect, located within the Company’s 2,002-ha contiguous Baie Verte gold-copper exploration package.  The Baie Verte project (“The Project”) is situated on the north central coast of the island of Newfoundland in the province of Newfoundland and Labrador, Canada.

The complete geochemical results received June 27, 2025, from SGS Canada, support preliminary interpretations that Copper Creek represents the stockwork feeder zone of a Volcanogenic Massive Sulphide (“VMS”) mineralizing system. In addition to stockwork chalcopyrite mineralization the program identified additional hallmarks of VMS systems including anomalous zinc mineralization and lenses of massive and semi-massive pyrite.

Copper Highlights Include:

• 3.6m of 1.49 % Cu Including 0.9m of 3.22 % Cu within 6.1m of 0.99 % Cu in hole CC-25-001 beginning at 31.7m downhole 

• 6.6m of 0.44 % Cu Including 0.6m of 1.97 % Cu in hole CC-25-002 beginning at 15.2m downhole 

• 3.6m of 0.66 % Cu Including 1.8m of 0.92 % Cu Within 6.0m of 0.45 % Cu in hole 25-CC-006 beginning at 19.0m downhole. 

• 4.1m of 0.56 % Cu Including 1.4m of 1.43 % Cu in hole 25-CC-014 beginning at 45.7m downhole.  

Zinc highlights include:

• 3.0m of 0.34 % Zn Including 1.0m of 0.69% Zn in hole 25-CC-006 beginning at 47m downhole. 

Further significant results from the drilling program are presented in Table 1, and an image of Chalcopyrite mineralization from hole 25-CC-002 is presented below in Figure 2. Figure 3 displays significant intercepts from holes 25-CC-014 and 25-CC-015 in cross section.

Modelling work is underway to place these results within the geological context of the project and the Company is planning follow-up exploration activities to evaluate the potential of this mineral system.

“We are excited and encouraged by these results. Copper Creek’s maiden diamond drilling program has succeeded in identifying a VMS mineralization system at Copper Creek confirming the favorable geological setting at our Baie Verte Project,” said Leocor CEO, Alex Klenman.  “There is much work ahead of us to now fully evaluate the potential of the VMS  system and we’re eager to get boots back on the ground to follow up this discovery,” continued Mr. Klenman.

The Baie Verte Peninsula has a well documented mineral endowment which includes several past producing VMS mines. Bedrock geology of the project area includes mafic volcanic and metasedimentary sequences of the Notre-Dame Subzone of the Dunnage Zone of the Newfoundland Appalachians. The Notre-Dame Subzone is characterized by Ordovician submarine bimodal volcanics, metasedimentary rocks and ophiolite sequences from a volcanic arc environment. This geological setting is consistent with the development of exhalative and replacement type VMS deposits. The most notable occurrences within the Notre Dame Subzone on the Baie Verte Peninsula include the past producing Terra Nova, Rambler, and Tilt Cove Mines. Figure 1 below outlines notable mineral deposits within the Baie Verte Peninsula.

Copper Creek Drilling

In March of 2025 the company completed a campaign comprising 21 diamond drillholes totalling 2308.5 meters at Copper Creek. The program was designed to follow up on significant and widespread copper anomalism in soils and shallow Rotary Air Blast Drilling completed by the company in 2022. The 2025 program represents the maiden diamond drill program on the Copper Creek prospect. Drillhole Collar information is detailed in Table 1.

David Murray, P.Geo., Principal Consultant at Resourceful Geoscience Solutions, A Consultant to Leocor is an Independent Qualified Person within the meaning of National Instrument 43-101 Standards of Disclosure for Minerals Projects, has reviewed and approved the technical information presented herein.

Laboratory Technical Note

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