GOLD: Rubicon is bulk sampling at Phoenix



The mill at the Phoenix gold project is treating a 25,000 to 30,000 tonne bulk sample from three test stopes in the F2 deposit.

ONTARIO – Rubicon Minerals Corp. of Toronto has begun processing the bulk sample from test mining at the F2 deposit at the Phoenix gold project in the Red Lake district. Between 25,000 and 30,000 tonnes of material will be processed from three test stopes.

The mineralized material from two of the test stopes has been stockpiled on surface, and blasting is underway on the third. The company is using sublevel longhole stoping to determine if bulk mining methods are feasible.

The Phoenix project includes a 1,250-t/d mill, and it is being commissioned to process the bulk sample. The material is being processed in batches, one for each of the test stopes. Cleaning between batches will ensure that the data collected can be interpreted individually.

Rubicon will reconcile the bulk sample results to the 2018 resource block model for the tested areas. A new geological model will then be created by the end of this year.

Rubicon president and CEO George Ogilvie said, “Test mining activities went relatively well with the No.977 and No.015 test stopes and we are currently blasting the No.161 test stope to give us the 25,000 to 30,000 tonnes of mineralized material for our bulk sample program.”
