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

(TheNewswire)

• VMS Mineralized System Confirmed

Vancouver, British Columbia – TheNewswire - July 8, 2025 - Leocor Mining Inc. (the “ Company ” or “ Leocor ”) (CSE: LECR, OTCQB: LECRF;Frankfurt: LGO0) (formerlyLeocor Gold Inc.), a junior resource companyfocussed on the exploration and development of precious metals projects in Eastern Canada, is pleased to report final assayresults from its recently completed maiden drilling program at theCopper Creek prospect, located within the Company’s 2,002-hacontiguous Baie Verte gold-copper exploration package.  The BaieVerte project (“The Project”) is situated on the north central coast of the island ofNewfoundland in the province of Newfoundland and Labrador,Canada.

The complete geochemical results received June 27,2025, from SGS Canada, support preliminary interpretations that CopperCreek represents the stockwork feeder zone of a Volcanogenic MassiveSulphide (“VMS”) mineralizing system. In addition to stockworkchalcopyrite mineralization the program identified additionalhallmarks of VMS systems including anomalous zinc mineralization andlenses 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 holeCC-25-001 beginning at 31.7m downhole

• 6.6m of 0.44 % Cu Including 0.6m of 1.97 % Cu in holeCC-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 hole25-CC-006 beginning at 19.0m downhole.

• 4.1m of 0.56 % Cu Including 1.4m of 1.43 % Cu in hole25-CC-014 beginning at 45.7m downhole.

Zinc highlights include:

• 3.0m of 0.34 % Zn Including 1.0m of 0.69% Zn in hole25-CC-006 beginning at 47m downhole.

Further significant results from the drilling programare presented in Table 1, and an image of Chalcopyrite mineralizationfrom hole 25-CC-002 is presented below in Figure 2. Figure 3 displayssignificant intercepts from holes 25-CC-014 and 25-CC-015 in crosssection.

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.

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

The Baie Verte Peninsula has a well documented mineralendowment which includes several past producing VMS mines. Bedrockgeology of the project area includes mafic volcanic andmetasedimentary sequences of the Notre-Dame Subzone of the DunnageZone of the Newfoundland Appalachians. The Notre-Dame Subzone ischaracterized by Ordovician submarine bimodal volcanics,metasedimentary rocks and ophiolite sequences from a volcanic arcenvironment. This geological setting is consistent with thedevelopment of exhalative and replacement type VMS deposits. The mostnotable occurrences within the Notre Dame Subzone on the Baie VertePeninsula include the past producing Terra Nova, Rambler, and TiltCove Mines.

Copper Creek Drilling

In March of 2025 the company completed a campaigncomprising 21 diamond drillholes totalling 2308.5 meters at CopperCreek. The program was designed to follow up on significant andwidespread copper anomalism in soils and shallow Rotary Air BlastDrilling completed by the company in 2022. The 2025 program representsthe maiden diamond drill program on the Copper Creek prospect.Drillhole Collar information 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 drill core by sawing.This contractor transported core between the logging, sawing andLaboratory locations. Sample Preparation took place at SGS’ facilityin Grand Falls-Windsor, Newfoundland and Labrador, analysis wasconducted at SGS Burnaby British Columbia. Samples were crushed to 75%passing 2 mm, riffle split 250 g and pulverized to 85% passing 75microns. Au assays were conducted on 30g of pulverized material usingthe Fire Assay method with a 4-acid digestion. Multi-element analyses,including base metals, were conducted on pulverized material using theICP method for 40 elements. Laboratory over-limits analysis methodswere applied as required. A systematic QAQC protocol was employed thatincludes systematic insertion in the sample stream of certifiedreference materials and blank samples, plus analysis of duplicate pulpsplits and ¼ core duplicates.
