Bonterra Resources Inc. announced the completion of a high-resolution helicopter-borne gravity survey and the commencement of a ground induced polarization ("IP") survey at its Desmaraisville North and South Properties (the "Properties"). These comprehensive gravity and IP surveys are expected to assist the Company in its 2024 exploration program by generating exploration targets. Bonterra contracted Sander Geophysics Ltd. ("SGL") based in Ottawa, Ontario to conduct a high- resolution helicopter-borne gravity survey on its Properties.

The survey consisted of a total of 1,583 line-kilometers (" km") at 200 meters ("m") flight-line spacing and flown at a 60 m elevation over the entirety of the Properties. The surveyed area covers the Opawica-Guercheville corridor of deformation where numerous gold showings have been previously discovered and historical gold mineral resources have been estimated. The survey is expected to be completed by year end and will be used in combination with the gravity survey to identify and explore disseminated and massive sulfide mineralized zones in the Company's as part of the Company's 2024 exploration program.

In early December, Bonterra mobilized one drill rig south of the old Coniagas Mine to drill test the deep southwest plunge of a zinc, lead, and silver mineralized orebody. InnovExplo of Val-d'Or, Quebec was contracted to compile and generate this exploration drill target. After the completion of the 900 m deep hole, Bonterra intends to contract AG to complete an InfiniTEM®?

XL BHEM survey with a patented loop configuration with depth potential up to 1,000 m. Historical production at Coniagas was over 700,000 tonnes at 10.8% Zn, 1% Pb and 183 g/t Ag.
