Tintic Regional Exploration



The East Tintic district has historically been recognized as an area prospective for large porphyry style Cu-Au-Mo mineralization. The Tintic District is located only 60 miles south of Kennecott’s iconic Bingham Canyon Cu-Au-Mo porphyry deposit, and displays many similar hallmarks for a potential large mineralized porphyry system at depth.

The East Tintic is located immediately northeast of the Silver City Stock and Treasure Hill monzonite, that have and currently are being explored for porphyry-style mineralization by a number of major mining companies. TCM’s land holding within the East Tintic district displays significant surface alteration driven by a large ( or several large) hydrothermal systems at depth. A number of silica-alunite lithocaps associated with porphyry emplacement are exposed at surface, and are surrounded by a significant metal endowment of carbonate replacement base-metal mineralization, with the Tintic district having a larger surface geochemical footprint than the area surrounding Bingham Canyon.

Three large lithocaps are identified on TCM’s property, these being:

  • Big Hill lithocap, that was variably explored by Anglo American and Kennecott between 2008 to 2014
  • Silver Pass lithocap, with only 2 drill holes completed by Kennecott in 2014 remains under-explored
  • Government Canyon lithocap, identified from regional spectral data and acquired by TCM in late 2019 remains under explored

Both Anglo American and Kennecott previously conducted periods of porphyry exploration on the property between 2008 to 2014, with a number of deep drill holes completed to typical depths of 1,200m. Four drill holes were completed by Anglo American into the Big Hill target, with Kennecott later drilling groups of one and two holes into a number of other porphyry targets, including only 2 holes into the Silver Pass lithocap. TCM interprets both the Silver Pass and Big Hill lithocaps to remain under explored given the surface alteration and tenor of the surrounding halo of base-metal mineralization. In particular the margins and structural corridors passing through the lithocap areas remain unexplored, where historic records appear to document altered porphyry and different porphyritic intrusive phases intersected within adjacent underground working, with elevated Cu mineralization recorded.

The Government Canyon area located 2 miles south of the main TCM land holding was acquired after regional spectral data lead the company to conduct a field reconnaissance trip, identifying a significant silica-alunite lithocap exposed at surface. The Government Canyon area is dominated by a strong east-west structural fabric and is one of the few canyons with this structural trend to report anomalous copper from earlier exploration completed by Anaconda during the 1960’s.

The technical team at TCM brings with it a strong background in porphyry exploration and discovery, having discovered and drilled the large Malmyzh Cu-Au porphyry system in Far East Russia prior to acquisition of the TCM property. A review of the previous porphyry exploration completed to date on the TCM property, in addition to further field mapping, sampling and deep penetrating geophysical surveys are planned by TCM over the prospective porphyry areas within the company’s land holding.
