Test Results Show Heap Leaching Best for Processing Ore
Research Report

Share on Stocktwits


Metallurgical tests on ore from a gold project in Idaho yielded an 87% average metal recovery and showed quick leach times, noted a PI Financial report.

Liberty Gold Corp. (LGD:TSX; LGDTF:OTCQX) announced that metallurgical findings on tested material from the Black Pine project's Rangefront zone "support a technically simple, low initial capital, low operating cost, run-of-mine heap-leach processing route" for this U.S. operation, reported PI Financial analyst Chris Thompson in a March 23 research note. Mineralization at Rangefront accounts for one-quarter of the Black Pine resource.

"We are encouraged by the results," Thompson wrote.

The analyst indicated that PI Financial rates the Canadian explorer Buy and has a CA$0.90 per share target price on it. In comparison, Liberty's current share price is about CA$0.54, implying an attractive potential upside from here.

Gold Recoveries a Beat

Thompson presented the highlights of the metallurgical testing results.

On testing of 24 composites, 87% of gold was extracted on weighted average, with overall recoveries ranging from 54.1–95.8%. This average was the highest percentage to date for Black Pine and well above PI Financial's modeled 74%, noted Thompson.

Also, the 87% average recovery was achieved on material with grades comparable to the figure PI Financial models as Black Pine's average life-of-mine (LOM) grade, 0.5 gram per ton gold.

Other Positive Findings

Thompson also pointed out that the heap-leach process was fast. More than 80% of gold was recovered within 10 days of column leaching.

Further, testing showed that particle size did not affect gold recovery amounts and that the relationship between recoveries and grades was predictable.

All of these findings, noted Thompson, suggest heap leaching is the ideal method for processing the oxide gold mineralization at Black Pine.

Production Estimate Unchanged

These recent metallurgical tests, wrote Thompson, are a "nice follow on" to the updated Black Pine resource estimate released last month.

"The resource estimate and metallurgical results released to date confirm our view of Black Pine's potential to deliver about 200 ounces of gold in average annual production over a healthy 10-year-plus LOM," Thompson wrote.

What To Watch For

Metallurgical testing continues, with two additional phases planned. One, phase 4B, will be on 25 composites from the Discovery, F and M zones and the E, A and Tallman pits. The other, phase 4C, will be on 12 composites from the C-D pit.

An updated resource estimate on Black Pine will follow, sometime in H2/23, and will include results from the 4B and 4C, as well as 4A, testing phases.
