Leocor Mining Plans VTEM Survey at the Baie Verte Gold-

Copper Project, Newfoundland

Vancouver, British Columbia – March 12, 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 announce it is planning a VTEM Survey (the

“Survey”) at the Company’s 2,002-ha contiguous Baie Verte gold-copper exploration

project. 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 will cover the entire project area and will generate critical informative data the

Company will utilize to assess and determine primary targets for follow -up drilling. Last

summer's drill program identified a VMS style mineralizing system within the Copper Creek

section of the Baie Verte project (see News Release dated July 8, 2025) . The fundamental

premise of applying electromagnetic (EM) methods to VMS exploration is the strong

conductivity contrast between the massive sulphide mineralization and the surrounding

host lithologies.

“We’re eager to get follow up drilling completed at Baie Verte,” said Alex Klenman, CEO of

Leocor Mining. “The discovery of VMS style mineralization last year was significant and the

case to continue drilling, particularly at Copper Creek, is certainly co mpelling. The survey

will aid greatly in prioritizing drill targets as we move forward with the development of the

Baie Verte project,” continued Mr. Klenman.

VMS deposits are syngenetic accumulations of sulphide minerals that form through

hydrothermal discharge in submarine volcanic environments, typically occurring as lenses

of polymetallic massive sulphide. These systems are characterized by two primary

components: a stratabound lens containing over sixty percent sulphide minerals and an

underlying discordant stringer or stockwork zone composed of vein -type mineralization

within an envelope of altered rocks. Both intersected in last year's drill program.

The electromagnetic signature of a VMS deposit is primarily a function of its mineralogical

composition and the connectivity of conductive grains. Common sulphide minerals such as

pyrite, pyrrhotite, and chalcopyrite possess extremely high electrical condu ctivity, often

resulting in orebodies with very low resistivities compared to host rocks like rhyolites,

andesites, or sedimentary sequences. This contrast can span up to five or more orders of

magnitude, providing ideal conditions for the induction of edd y currents during a time -

domain EM survey.

The VTEM system operates on the principle of time -domain electromagnetic induction. A

transmitter coil, carried by a helicopter, generates a primary electromagnetic field by

passing a powerful current through a large loop. In VTEM, this current follows a t riangular

ramp or polygonal waveform that is rapidly terminated. The collapse of this primary field

induces eddy currents in any nearby conductive bodies in the subsurface, such as a massive

sulphide lens. These induced currents generate a secondary magnetic field that decays over

time. VTEM measures the time rate of change of this secondary field using induction coil

receivers during the "off-time" between transmitter pulses.

More details will be provided once the survey dates are finalized.
