Corcel Exploration Announces Historical Critical Mineral Potential at Yuma King Project

CRCL · Price

Executive Summary

  • Corcel Exploration disclosed historic occurrences of high‑grade tungsten (up to 19.15 % WO₃) and extensive graphite/graphene mineralization at its 100 % owned Yuma King Project in Arizona.
  • The data are compiled from legacy drilling logs, geochemical sampling, and technical assessments; they have not been verified by the company’s Qualified Person due to missing original records.
  • Management indicated that these historic datasets will be integrated into ongoing copper‑gold exploration plans to evaluate whether follow‑up work on tungsten and graphite is warranted.

Key Details

  • Tungsten:
  • Historic production across a ~5 km² district (Three Musketeers, Jewel Anne, Pee Wee, Ace, Trioni).
  • Assays reported up to 19.15 % WO₃ in channel samples; multiple surface soil anomalies identified.
  • Historical mining occurred intermittently from the early‑1950s through the 1970s; mineralization occurs as scheelite within quartz veins, greisen zones, and thrust faults.

  • Graphite / Graphene:

  • Intersections from 2011–2016 drilling (hole AV‑2) show a 150 m thick carbonaceous mudstone body with a 25 m interval of high‑carbon material confirmed by Raman spectroscopy.
  • A 2016 four‑hole, 1,220 m drill program by Cash Capital extended the graphite horizon southward; detailed data not yet released.

  • Critical Mineral Context:

  • Both tungsten and graphite are listed as U.S. critical minerals with current full import reliance.
  • Potential strategic relevance for defense, aerospace, electronics (tungsten) and battery anodes/energy storage (graphite).

  • Qualified Person Statement:

  • Roy Greig, Ph.D., P.Geo, reviewed the technical content but could not verify the historic data because original documentation is inaccessible.

  • Forward‑Looking Plans:

  • Corcel will incorporate the historical datasets into its geological model and assess follow‑up exploration alongside existing copper‑gold programs.

Notable Quotes

“The available historical records indicate that the Yuma King Project contains multiple areas where tungsten and graphite mineralization were documented and, in some cases, mined on a small scale,” – Jon Ward, CEO & Director, Corcel Exploration.


Materiality Assessment: Non‑Material – Positive (the release provides potentially encouraging historic data but no verified resource estimate or immediate economic impact).
