Calico Resources Corp.(TSXV:CKB) reported that Resource Development Incorporated completed its review of historic metallurgical studies carried out on Grassy Mountain. Calico is currently reviewing additional test work for the project.

As quoted in the press release:

A significant portion of gold present in the ore is free milling and gravity recoverable. The higher the feed grade, the higher the proportion of gold which can be recovered in the gravity process. Therefore, a gravity concentration process can be incorporated into the grinding circuit.
Preliminary flotation tests did not recover significant amounts of gold in the concentrate. However, technologies have improved over the last two decades and several new reagents have been developed that can float fine free gold.
A cyanidation process can extract gold at a relatively coarse grind with reasonable reagent consumptions.
The ore is generally hard and abrasive and that the least expensive method to achieve the desired grind size will likely be by a three stage crushing circuit followed by ball milling.

Calico Resources Corp., President & CEO, Bill Wagener, said:

The high gold recoveries indicated by the review of the historic studies, coupled with the drill results of high-grade core targeted by the 2011 exploration program are indicative of a project with resilience at a wide range of gold prices.
