Happy Creek Minerals Ltd. reported that field work is complete at the Company's 100% owned, 240 square-kilometre Highland Valley project in southern British Columbia. A wide-spaced 3D audio-magnetotelluric (AMT) geophysical survey, soil geochemical sampling, mapping and prospecting, and a 3D magnetic inversion were completed on the Rateria portion of the property. The new work was completed in the vicinity of the Zone 1 and Zone 2 copper deposits, as well as the lightly explored Mystery and Billy Lake targets.

Geology and rock sampling was also performed on the Abbott portion of the Company's West Valley property. Soil and rock samples have been delivered to the lab and results are expected in early 2024. Highlights of the work include: 175 soil and stream sediment geochemical samples were collected, primarily over the Mystery target and east of Billy Lake, where coverage was previously lacking.

Follow-up geological mapping, prospecting and rock sampling was performed at the Mystery, Zone 2 Northeast Extension, Billy Lake, and West Sho targets on Rateria property, and at the Abbott prospect on the West Valley property. For the first time in the history of this project area, a ground-based audio-magnetotellURic survey was completed in the northern part of the Rateria property. AMT is a natural-source geophysical method that measures changes in earth resistivity that can be associated with changes in rock types, alteration, structure and sulphide mineralization, The method is a deep-looking complement to shallow resistivity information collected through previous IP-DC resistivity surveys.

Three proof-of-concept AMT test lines were completed first and preliminary results suggest the method is successful in identifying large-scale conductive zones extending to over one kilometre in depth at the Mystery, Zone2 Northeast Extension, and Billy Lake target areas, which are known to contain porphyry style copper mineralization near surface. Based on these preliminary test lines, additional AMT surveying was completed to infill and expand the coverage area more completely around the Zone 1 and Zone 2 Copper deposits that remain open. Processing of a 3D inversion model of the AMT data is now underway.

Finally, the Company completed 3D in versions of the 2021 Rateria airborne magnetic survey. Porphyry copper mineralization on the project and in the greater Highland Valley mining district is generally associated with relative magnetic low features. Like the AMT survey, magnetic inversion provides a 3D model from surface to over one kilometre below surface to help identify potential porphyry copper centres which are associated with magnetic destructive alteration and/or intrusions with a low magnetite content.
