Brixton Metals teams up with Eldorado on Atlin Goldfields project
Located 9 km east of the town of Atlin, BC, the property comprises a 579-square-kilometre claim group.
Great Bear Resources (TSXV: GBR) has completed preliminary metallurgical tests on samples from the LP fault at its Dixie gold project, in northwest Ontario, reporting gold recovery of between 95.2% and 99.2%.
The Dixie project in the Red Lake gold camp, 25 km west of town, is wholly owned by the junior. An initial resource estimate is expected in early 2022.
Ten 1-kg samples from the LP fault were processed in a standard 48-hour bottle roll test at 40% solids with a 1 g/L sodium cyanide (NaCN) solution. The samples contained material of various grades, host rock, sulphide content and alteration styles. The highest recovery rate, 99.2%, belonged to the samples with the highest grade, over 20 g/t gold. The mineralization is described as free milling and not refractory.
The LP zone samples that were tested represent the most mineralogically complex intersections drilled to date. They had higher accessory sulphide content than the zone’s average, but that did not have a measurable effect on recovery. More tests are underway on low-sulphide material.
Great Bear expects that a gravity gold circuit will result in good gold separation. The company does not think an autoclave will be needed in the flowsheet to treat LP fault ore.
Similar earlier metallurgical tests of samples from the Dixie Limb and Hinge zones had recovery rates between 88.3% and 97.5% of the gold.
Great Bear continues to drill high and very high grades at Dixie, ahead of an initial resource estimate expected early next year.

We have very rich gold reserves in the National park ? and alongside lake Victoria on virgin land. Send me your WhatsApp number and I will send you the professional geological report from Geological Survey of Tanzania. Exploration and drilling results are incorporated.

The abundance of the gold and Silver ore in Tanzania is including the diversity of rare earth minerals like South Africa. Send me your WhatsApp number. To access the valuable information
