We received on behalf of Prismo Metals Inc.and we are glad to publish the following press release :
“Prismo Metals Inc. (the “Company”) (CSE: PRIZ) (OTCQB: PMOMF) is pleased to announce the appointment of Jamie J. Wilkinson, Professor of Geology at Imperial College London and Senior Mineral Exploration Consultant, to assist with the application of advanced propylitic alteration mineral chemistry techniques at its Silver King project in the Pioneer Mining District near Superior, Arizona.
Prof. Wilkinson will work directly with Prismo’s technical team, led by Chief Exploration Officer Dr.
Craig Gibson, and Special Advisor Dr. Linus Keating, to deliver a focused, high-impact evaluation of
the extensive propylitic “green rock” alteration halo that surrounds known mineralization and
geophysical anomalies at Silver King. This halo — dominated by chlorite, epidote and pyrite — forms
a large geochemical footprint that can extend several kilometers from a porphyry center and is
particularly well developed in the same Laramide-aged volcaniclastic breccias, sandstones and
Proterozoic dolerite sills that host the giant Resolution porphyry Cu-Mo deposit only 3.4 km away.
The program will proceed in four integrated stages:
Strategic site selection: Prof. Wilkinson will collaborate with Drs. Gibson and Keating to identify and
prioritize approximately 20 optimal sample locations across the propylitic alteration zone. Sites will
be chosen based on existing mapping, pyrite halo distribution, hydrothermal breccias, geophysical
targets and distance to known mineralization to maximize vectoring potential.
High-precision sampling and analysis: Representative samples will be collected and analyzed using
state-of-the-art, in-situ techniques — electron microprobe for major and minor elements plus laser
ablation ICP-MS (LA-ICP-MS) for a full suite of trace elements — using laboratories and staff
experienced in the approach at the Natural History Museum in London. Both chlorite and epidote will
be systematically analyzed grain-by-grain.
Quantitative vectoring and 3D modeling: Prof. Wilkinson will apply the chlorite proximitor
methodology (which he co-developed) together with complementary epidote chemistry and chlorite
geothermometry. Key element ratios (such as Ti/Li, Ti/Sr and V/Co) and temperature-sensitive
indicators vary systematically with distance from the porphyry center.
These ratios can change by several orders of magnitude across the propylitic halo, enabling calculation of distance to the hydrothermal center (typically with uncertainties of a few hundred meters). Discrimination methods using chlorite and epidote chemistry will be used to screen samples for false anomalies related to epithermal overprints and data will be evaluated to assess potential metal endowment of the system.
The team will integrate these results with thermal gradients to generate robust 3D vector models
that point toward the most likely location of the concealed porphyry copper-molybdenum system.
Technical reporting and drill targeting: Prof. Wilkinson will deliver a comprehensive report
interpreting all mineral chemistry data, including prioritized 3D drill targets. This will directly inform
Prismo’s Phase 2 drilling program and help de-risk targeting in areas of post-mineral cover or distal
propylitic alteration.
This approach builds directly on the successful blind test of the same methodologies at the Resolution
Copper deposit (Cooke et al., 2020, Economic Geology), where LA-ICP-MS chlorite data and
proximitor calculations from a limited suite of propylitic samples precisely located the concealed
porphyry center between sample clusters — a target that would have resulted in the discovery of
Resolution Copper beneath thick Tertiary cover. The shared Laramide geology, alteration style, and
district setting make these tools highly applicable at Silver King.
“I am excited to collaborate with the Prismo team, including Dr. Craig Gibson and Dr. Linus Keating,
on the Silver King project,” said Prof. Wilkinson. “The propylitic alteration halo offers a powerful,
underutilized search space. By applying chlorite and epidote mineral chemistry — particularly
proximitor ratios validated at the nearby Resolution deposit — we hope to be able to systematically
vector toward the magmatic-hydrothermal center even under cover, refining targets with a precision
that complements traditional mapping, geophysics and drilling.”
“Bringing Prof. Wilkinson on board represents a major step forward for Prismo’s next phase of drilling
at Silver King,” said Alain Lambert, CEO of Prismo Metals. “His expertise in using trace-element
chemistry of chlorite and epidote to vector within green rock alteration, proven in the blind test at
Resolution only 3.4 km away in the same Laramide host rocks, directly strengthens our ability to
locate concealed porphyry systems at Silver King. Having Prof. Wilkinson working with our team will
enable us to generate high-confidence, data-driven targets for Phase 2 drilling.”
“The ‘green rock’ targeting methodologies are a perfect fit for our evolving model at Silver King”
added Dr. Craig Gibson, Ph.D., CPG, Chief Exploration Officer. “Integrating high-resolution mineral
chemistry vectors with our Phase 1 drilling results, mapping of pyrite halos and hydrothermal
breccias, and geophysical data — in close collaboration with Dr. Linus Keating — will provide a robust
framework to locate the porphyry source. This scientific approach significantly enhances our
exploration in this highly prospective district.”
About Prof. Jamie J. Wilkinson
Prof. Jamie J. Wilkinson PhD is a leading economic geologist specializing in the geochemistry of
hydrothermal systems and the development of mineral chemistry tools for porphyry exploration. He
is Professor of Geology at Imperial College London and co-founder of the London Centre for Ore
Deposits and Exploration (LODE), a joint initiative between Imperial College and the Natural History
Museum, London. He is currently also a senior consultant in mineral exploration, working globally
with Barrick Mining Corp. (TSX: ABX). He was involved in the development of the green rock targeting
methodology (e.g. Wilkinson et al., 2015) and has been involved in its successful application across a
range of porphyry systems, including the blind test validation at Resolution, Arizona (Cooke et al.,
2020). This work has shown that chlorite and epidote trace-element chemistry can define large exploration footprints and deliver quantitative vectors even in distal or covered propylitic
environments.
