PROSPECTAIR GEOSURVEYS COMPLETES A HELIBORNE TIME DOMAIN EM SURVEY AT SLEEPING GIANT SOUTH PROPERTY, QUEBEC

Prospectair Geosurveys, of Gatineau, Que., has successfully completed a heliborne time-domain electromagnetic (TDEM) survey on Muzhu Mining Ltd.'s wholly owned Sleeping Giant South property, located in the region of Abitibi-Temiscamingue in Quebec, Canada.

The property abuts the mineral tenures of the Sleeping Giant mine of Abcourt Mines Inc. Abcourt recently announced that it has secured debt financing of $8-million (U.S.) (approximately $11-million (Canadian)) to complete the financing required for the restart of its Sleeping Giant mine and mill. In addition to Abcourt, the district is being actively explored by Agnico Eagle Mines Ltd. (through its acquisition of O3 Mining Inc.) and Midland Exploration Inc.

Prospectair was commissioned to test a central six-kilometre east-west segment of the property with the ProspecTEM time-domain system with a 5.6-metre loop diameter. According to the report received from Dube (2025): "ProspectTEM is a powerful lightweight system adapted for small-size helicopters and easy manoeuvrability, enabling the system to be flown as close to the ground as safely possible and ensuring maximum data resolution. Advanced signal processing technique and a full processing package was developed in house to optimize the ProspecTEM data."

Prospectair previously surveyed the property for Muzhu with a high-resolution heliborne magnetic survey (Dube, 2021) that shows distinct, east-west linear magnetic responses.

The new TDEM data show adjacent, continuous conductors correlative to the Laflamme-Nord shear zone and the volcanic-sedimentary units described in the National Instrument 43-101 technical report by Charbonneau (2021) as the Vanier-Dalet-Poirier Group, which also hosts the gold deposit at the Sleeping Giant mine.

This new TDEM survey will form a robust foundation for the restart of gold exploration on the property, in combination with data from historical work and the Prospectair high-resolution magnetic survey.

Muzhu has retained Quebec-based geoscience consulting services to assemble the historical drilling and sampling, and submit recommendations for property exploration and drill targeting.
