Leocor Mining Plans VTEM Survey at Baie Verte Gold-Copper Project

Vancouver, British Columbia — March 12, 2026 — Leads & Copy —

Leocor Mining Inc. is planning a VTEM Survey at the company’s 2,002-hectare contiguous Baie Verte gold-copper exploration project.

The Baie Verte project is situated on the north central coast of Newfoundland.

The survey will cover the entire project area and will generate 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.

The fundamental premise of applying electromagnetic methods to VMS exploration is the conductivity contrast between the massive sulphide mineralization and the surrounding host lithologies.

CEO of Leocor Mining, Alex Klenman said the discovery of VMS style mineralization last year was significant. Klenman added that the survey will aid greatly in prioritizing drill targets as the company moves forward with the development of the Baie Verte project.

VMS deposits are 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 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.

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 conductivity, 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 eddy 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 triangular 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.

Leocor Mining Inc. is a British Columbia-based resource company involved in the acquisition and exploration of precious metal projects, with a current focus in Atlantic Canada. Leocor, through outright ownership and earn-in agreements, currently controls several gold-copper projects in prime exploration ground located within the prolific Baie Verte Mining District. Leocor’s Bae Verte portfolio includes the Dorset, Dorset Extension, Copper Creek and Five Mile Brook projects, creating a contiguous ~2,000-hectare exploration corridor.
