Illinois Creek Project Exploration Update
CRD Model Driving Exploration
What are CRD's?
✔ CRD's are the fingertip of the porphyry-skarn-CRD system
✔ Carbonate-hosted
.
Thick packages of dolostone host rocks in IC district =
potential for mineralization
✔ Intrusion-related
Porphyry is driving the system (still undiscovered at IC)
✔ Multiphase + Polymetallic (Zoned)
•
.
Ag-Pb-Zn (WPC) Au-Ag-Cu (IC)
High-temp (>250°)
✔ Formed by the direct continuous replacement of carbonate
rocks by massive sulfides
•
Entire mineralized system are often km's in length
✔ Ore body morphology
.
•
Mantos - lateral massive replacement of selective
beds (horizontal)
Chimneys thick structural cross cutting bodies
(vertical)
