Leocor Mining commences VTEM survey at Copper Creek, Baie Verte

Vancouver, British Columbia – July 28, 2026 – TheNewswire – 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 the commencement of a VTEM tm Plus airborne EM survey (the “Survey”) by Geotech Ltd. (“Geotech”) at the Company’s Copper Creek prospect (the “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 Survey follows up the Company’s maiden 2025 drilling campaign on the Prospect which succeeded in identifying stockwork chalcopyrite mineralization interpreted to represent feeder type mineralization 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. Results of the 2025 drilling campaign are disclosed in Company news release dated July 8 th , 2025, titled: “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.” Click Image To View Full Size Figure 1: Leocor’s Baie Verte Project location, Newfoundland, Canada “We are pleased to commence this survey at Copper Creek following the success of our maiden drill campaign,” said Alex Klenman, CEO. “We remain committed to a disciplined, systematic exploration approach and believe this survey will play an important role in identifying additional high-priority targets.

Our Baie Verte project is in a highly prospective district, and we look forward to advancing exploration there,” Mr. Klenman added. About VTEM TM Plus Geotech Ltd.’s proprietary VTEM™ Plus system is a helicopter-borne time-domain electromagnetic technology that maps subsurface variations in electrical conductivity and magnetic susceptibility. The system is highly effective for VMS exploration because dominant sulfide minerals, including chalcopyrite and pyrite, display strong electrical conductivity contrasts against unmineralized host rocks.

VTEM™ Plus uses a low base operating frequency to penetrate to depths up to 500 meters.

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.
