Leocor Mining Commences VTEM airborne EM survey at

Copper Creek, Baie Verte, Newfoundland

Vancouver, British Columbia – July 28, 2026 – 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”) mineralizi ng

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 8th,

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.”

“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 VTEMTM 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, includin g 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.

About the Project

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 2 below outlines notable mineral deposits within the

Baie Verte Peninsula.
