Bench scale pressure leach tests have confirmed the amenability of Birch Lake flotation concentrates to the proprietary Platsol(R) process. High metal extractions were obtained for all of the significant metals of interest except for gold, which yielded a lower recovery than anticipated.

Franconia President Brian Gavin said: "We are very pleased by the positive results of the pressure leach (Platsol(R)) tests. These results confirm that, at the bench scale, flotation methods can be used to produce a concentrate potentially suitable for hydrometallurgical hy·dro·met·al·lur·gy  
n.
The treatment of metal or the separation of metal from ores and ore concentrates by liquid processes, such as leaching, extraction, and precipitation.
 processing, which further strengthens our belief in the potential economic viability of the Birch Lake project."

The results of the flotation and pressure tests will permit more definitive planning of production plant design, metal recoveries, and capital/operating costs. On the basis of these results Franconia intends to re-estimate the resource at Birch Lake (to NI 43-101 standards) and then commission a NI 43-101 compliant independent Preliminary Economic Assessment. This report will include a "scoping-level" economic evaluation, including a cash flow analysis, of the potential viability of the project prior to any eventual preliminary feasibility study.
