Happy Creek Minerals Ltd. Completes Field Work at Highland Valley

December 18, 2023, Vancouver, British Columbia – Happy Creek Minerals Ltd. (TSX -V: HPY)

(“Happy Creek” or the “Company”) is pleased to report 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 (see October 11, 2023

news release) . 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.

Happy Creek’s President and Chief Executive Officer Mr. Michael Cathro commented: “The

Company is constantly trying to squeeze the most information we can from relatively low-cost

exploration tools. Preliminary results of the AMT survey are very promising in identifying large

electrically conductive anomalies near known copper mineralization. We eagerly await the final

3D inversions for the AMT and magnetic data. These are deep- looking surveys that can help

identify large-scale structures associated with porphyry copper centres and will help guide future

drilling”.

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, Zone 2 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 inversions 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.

About Highland Valley

The 100- percent-owned Highland Valley project, comprising the contiguous West Valley and

Rateria properties, covers 240 square kilometres and is a quality, underexplored exploration

copper asset in the world-class Highland Valley district. The Company’s property package adjoins

the Highland Valley Copper (HVC) mine. The mine, Canada’s largest copper producer, has been

in production for 60 years 1. Happy Creek’s Zone 1 and Zone 2 discoveries, which lie just 6.5

kilometres southeast of HVC’s Highmont open pits*, show laterally continuous mineralization that

has been outlined with 28,000 metres of drilling and remain open in several directions. The

Company also continues to generate new copper targets within this large and prospective

property.
