Trixie ores fall into different Categories that could be sold or processed differently. They are as follows:
- The “specialty ore” consisting in extremely high “bonanza” grades that could be marketed as Direct Smelting Ore and expected to run in the 10’s of ounces,
- The “high grade” zones expected to run 5 oz per ton,
- The “normal high grade” zones expected to run > 0.6 oz per ton,
- The “low grade” ores which related to surface stockpiles that average 0.3 oz per ton.
Since the discovery of these different ore types, the Management Team has been focused on optimal underground exploration and development of Trixie’s resources. In parallel, laboratory assays and analysis and pilot plant tests have focused on determining the optimum processing of the different ores to maximize recoveries and sale of the gold therein.
Results to date have demonstrated that the Trixie ores are generally amenable to whole ore cyanide leaching achieving recoveries of 90 percent gold with by-product silver. Test work continues in order to establish a definitive process plant flowsheet which would allow for installation of necessary processing steps in the existing Tintic processing plant.
TCM is also conducting a full scale pilot testing on an innovative gravity gold and flotation process at a third party process plant with circuit optimization underway. Historically, Trixie ores were processed using flotation with concentrates being sold to copper smelters.
In addition, major nearby processing facilities are engaged currently with TCM for potential ore sales and processing by a third party offering balance sheet flexibility.
