How High Can Copper Grades Go at TechGen’s Red Devil Prospect?

Mining By Maxwell Dee 3 min read

TechGen Metals reports outstanding high-grade copper assays up to 40.9% from its Red Devil Prospect in Western Australia, highlighting a compelling geophysical target that could underpin significant mineralisation.

  • High-grade copper rock chips up to 40.9% Cu with anomalous silver and gold
  • Strong induced polarization (IP) chargeability anomaly identified at 175-225m depth
  • Red Devil target associated with two parallel fault zones and high resistivity basement
  • Two prime drill targets, Red Devil IP anomaly and Blue Devil EM conductors
  • Potential for large copper-gold-silver mineral systems related to intrusion styles

Exceptional Surface Assays Signal New Potential

TechGen Metals Limited has revealed a fresh batch of high-grade copper rock chip results from its Red Devil Prospect, part of the broader Blue Devil Project in the East Kimberley region of Western Australia. The standout assays include copper concentrations soaring above 40%, alongside notable silver and gold values, underscoring the prospect’s rich mineral potential despite limited prior detailed exploration.

Geophysical Surveys Illuminate a Strong Target

The company’s recent induced polarization (IP) survey has delineated a robust chargeability anomaly at depths between 175 and 225 metres. This anomaly, named Red Devil, aligns with two northwest-southeast trending fault zones visible at surface and correlates with zones of high resistivity in the basement rock. Such geophysical signatures are often indicative of sulphide mineralisation, bolstering the prospect’s appeal.

Dual Targets Poised for Drilling

TechGen now identifies two high-quality drill targets within the Blue Devil Project, the newly defined Red Devil IP anomaly and a set of three large-scale electromagnetic (EM) conductors associated with a deep magnetic intrusion. These targets represent different but complementary mineralisation styles, increasing the likelihood of uncovering significant copper-gold-silver deposits.

Strategic Implications and Next Steps

Managing Director Ashley Hood described the findings as “exceptionally encouraging,” noting the textbook nature of the intrusion-related anomaly and the mineralisation pathways along the fault zones. The company plans to advance exploration with further fieldwork and drilling to test the depth and extent of mineralisation, aiming to convert these geophysical and surface indications into a defined resource.

Broader Context in WA Copper-Gold Exploration

The Blue Devil Project sits within a highly prospective geological setting known for hosting various styles of copper and gold mineralisation, including porphyry, iron-oxide copper-gold, and skarn deposits. TechGen’s ongoing work builds on historical exploration and recent geophysical advances, positioning the company well in the competitive WA copper-gold exploration landscape.

Bottom Line?

With high-grade surface assays and compelling geophysical targets, TechGen’s next drilling campaign will be pivotal in defining the Red Devil’s true potential.

Questions in the middle?

  • Will upcoming drilling confirm the continuity and scale of the Red Devil mineralisation?
  • How might the dual targets at Blue Devil complement each other in a future resource model?
  • What are the implications of the anomalous silver and gold values for project economics?
