Snowline Gold Reports Positive Results From Initial Metallurgical Testing of Rogue Project’s Valley Discovery With Gold Recoveries From 88% to 96%

• High gold recovery realized with conventional processing techniques demonstrates the non-refractory nature of gold mineralization at Valley
• Average gold recovery from non-optimized methods ranges from 87.6% (average bottle roll cyanidation) to 95.7% (average carbon-in-leach)
• Strong buffering effect and low concentrations of deleterious elements carry positive implications for environmental aspects of processing, reclamation and closure
• Results open the door to multiple future processing options for Valley mineralization.

VANCOUVER, BC / ACCESSWIRE / June 14, 2023 / SNOWLINE GOLD CORP. (TSX-V:SGD)(OTCQB:SNWGF) (the "Company" or "Snowline") is pleased to announce results from initial, first-pass metallurgical testing of gold mineralization from the Valley discovery on its Rogue Project, Yukon Territory, Canada. Ten composite drill core samples representing various locations and grades within the Valley gold system were subject to bottle roll cyanidation, carbon-in-leach (CIL) and preliminary flotation amenability testing. Gold recovery from test work was favourable varying from 81% to 99% across a range of head grades, material size and metallurgical approach (Figure 1). The results demonstrate that mineralization at Valley is non-refractory and highlight the applicability of multiple processing techniques as options for further consideration.

Yellow bars indicate proportion of gold in particles >0.106 mm in size (left axis), an indicator for proportion of gravity recoverable gold.

"These positive initial metallurgical results mark an important milestone in the advancement and de-risking of our Rogue Project's Valley discovery," said Scott Berdahl, CEO & Director of Snowline. "The gold system at Valley has already demonstrated considerable scale, consistency in strong gold grades, and a simple near-surface geometry favourable to mining. Now we can attest confidently and quantitatively to its positive metallurgical properties as well. Gold is highly recoverable by various processing methods. The mineralization is naturally buffered and low in deleterious elements. Valley is a discovery that continues to deliver above expectations. With a third drill now turning on site, this is a terrific kick-off to our 2023 field season. We are excited to continue to advance both the Valley discovery and the broader, district-scale Rogue Project with our ongoing drill and surface campaigns."
