Galleon Gold Announces up to 98% Gold Recoveries from Metallurgical Studies at West Cache Project

In This Article:

Toronto, Ontario--(Newsfile Corp. - April 3, 2024) - Galleon Gold Corp. (TSXV: GGO) (FSE: 3H90) (the "Company" or "Galleon Gold") is pleased to announce excellent results from recent metallurgical test work (the "Study") performed on a composite sample representative of the material to be mined from the Company's planned 86,500 tonne exploration bulk sample.

The Study was undertaken to evaluate gold recoveries from flotation and gravity-flotation methods. In contrast, the Company's 2021 metallurgical work investigated cyanidation, gravity-cyanidation, and gravity-flotation-cyanidation on three composites of different grade ranges (see press release dated August 11, 2021). Both studies, carried out by SGS Canada's Lakefield, Ontario laboratory, indicate that Zone #9 gold is well-liberated and amenable to high recoveries by the various methods tested.

Highlights

  • Rougher flotation up to 98.5 % gold recovery

  • Gravity tailings flotation up to 97.1 % recovery

  • Rapid rougher flotation with ~95 % gold recovery in ~11 % mass pull with a plateau in ~15 % mass pull (see Figure 1)

  • 93 % of gold floated in the first two minutes for the flotation-only sample and 95 % in four minutes for the gravity-flotation sample (see Figure 2)

Note that on Figures 1 and 2 the term "Whole Ore" is used as part of SGS Canada's metallurgical testing terminology and does not imply that the material tested from the West Cache Gold Project is revenue-generating "ore" as defined by NI 43-101. "Whole Ore Test F1" refers to flotation of the composite sample without prior concentration by gravity recovery methods ("Gravity Tailings Test F2").

Comment from the CEO

David Russell, CEO and President of Galleon Gold comments, "We are very pleased with the recent metallurgical study as it confirms and builds upon earlier work included in the West Cache PEA completed in 2022. The ease with which the gold is recoverable by different methods opens up a variety of custom milling options for our bulk sample test."

Composite Sample

The composite sample was comprised from twenty-nine drill core samples from three holes into the Zone #9 area and planned bulk sample stopes, as shown in Figure 3. The average fire assay head grade was 8.90 g/t Au and the screened metallics grade was slightly higher at 9.26 g/t Au as shown in Table 1. A reconciled head grade of 9.35 g/t Au was calculated after the test work was complete, which confirms grade composites from infill drilling and resource estimation data in the bulk sample area.
