Copper Fox Extends Mineralized Envelope at Van Dyke ISCR Project
Rhea-AI Summary
Copper Fox (OTCQX: CPFXF) reports analytical results from 11 historical diamond drillholes at the 100% owned Van Dyke ISCR project, Arizona. Eight holes returned intervals above the 0.025% TSCu cutoff used in the 2020 MRE. DDH OXY-42 extended the TSCu envelope by 100.59 m to 436.78 m and included a 22.86 m interval averaging 0.409% TSCu.
Analyses focused on acid soluble and cyanide soluble copper; results from 18 additional holes are pending. True thicknesses remain unknown.

Analytical results for eight historical diamond drillholes from the Van Dyke project are reported in this news release. Analytical results from an additional 18 drillholes are pending. The analytical results of economic interest are acid soluble copper (ASCu) and cyanide soluble copper (CNCu). The TSCu (acid + cyanide soluble copper) cutoff grade used in the 2020 MRE was

Comments on Analytical Results
The 2026 sampling completed in DDH OXY-42 extended the TSCu mineralization from 336.19m to 436.78m, an additional 100.59m down dip. The TSCu envelope in this drill hole now extends from a core interval of 249.33m to 436.78m. The objective of the sampling program was to either fill data gaps identified in previous sampling programs or extend the limits of the TSCu envelope to better define the boundary between the Transitional and Sulphide copper domains within the Van Dyke deposit. Analytical results for three drill holes yielded below cutoff (
Quality Control, Sampling and Analytical Procedures
Copper Fox follows a rigorous Quality Assurance/Quality Control program. The 2026 sampling program consisted of 359 samples consisting of 332 pulp and core samples, 18 certified reference standards and 9 blanks from 29 historical drillholes.
Skyline Assayers and Laboratories Inc. (Accreditation 2953.01 and Standard ISO/IEC 17025: 2017) located in Tucson, Arizona completed sample preparation and analysis. The Transitional zone of the Van Dyke deposit is a mixture of acid soluble minerals (malachite, azurite, chrysocolla) and chalcocite, a secondary copper sulphide. Samples were prepared using preparation code SP-1 - Crush to plus
