Metallic Ore Resources

Texas has a long history of mining metallic ore resources throughout the state. Copper, lead, zinc, and silver have been explored for and mined in the Trans-Pecos region of west Texas for centuries, with production waning to almost non-existent today. There are still prospects and deposits, that could be economical in as more favorable market, and with emerging technologies that include critical ore minerals.

Metallic ore research projects include:

  • Shafter silver deposit
  • Red Hills copper-molybdenum prospect
  • Cave Peak molybdenum prospect
  • Zimpleman Pass Skarn prospect (Ag, Pb, Zn, Cu, Mo)
  • Quitman Mountains Bonanza and Alice Ray gold mines
  • Central Texas carbonate-hosted Pb deposits
  • Gulf Coast salt dome cap rock hosted Zn-Pb-Ag deposits

Research related to metallic ore mineral resources include:

  • Mineralization and genesis of ore deposits
  • Mineralogy, petrology, whole-rock chemistry, tectonics, structural geology, isotope geochemistry, geochronology, fluid and thermal history, mineralization, alteration and ore genesis
  • Exploration and interpretation with geospatial datasets
  • Estimation and reserve calculations of known and unknown resource potential
  • Economic potential and supply chain mapping
  • Supply and demand balances
  • Application and integration with global outlooks
  • Geographic (country, region, state, etc) resource and risk assessments and extractive issues
  • Environmental risk and regulatory compliance issues (chemical mitigation, water issues, subsurface monitoring, etc.)
