Bonanza Grade Silver identified ±550mtrs from historic silver mines that produced 34,200,000oz of refined silver

26 August 2024

White Cliff Minerals Limited (“the Company”) is delighted to announce it has received the final batch of assay results from rock chip samples taken during the maiden field program at the Great Bear Project (“Great Bear” or “the Project”), Northern Canada. Results confirm extraordinary silver grades from epithermal structures and polymetallic results from skarn-style mineralisation.

Truly outstanding silver results from Slider mark another high-grade discovery. Approximately 550m along strike to the NW from the two historical producing underground silver mines that produced 34,200,000oz of refined silver
Slider, a significantly expanded silver region a newly defined area of interest of at least 1.5km x 1.5km:
- includes a newly identified westerly extension of the two historical silver mines which includes a zone of native silver bearing breccias
- Results from Slider include bonanza silver concentrations shown below as percentage of silver, grammes of silver and ounces of silver:
  - 7.54% Ag (75,439g/t Ag or 2,425 Oz/t Ag) (F005907)
  - 0.91% Ag (9,070g/t Ag or 291 Oz/t Ag) (F005908)
  - 5.35% Ag (53,506g/t Ag or 1,720 Oz/t Ag) (F005909)
  - 0.71% Ag (7,100g/t Ag or 228 Oz/t Ag) (F005415)
  - 0.18% Ag (1,840g/t Ag or 59 Oz/t Ag) (F005416)
  - 0.27% Ag (2,700g/t Ag or 87 Oz/t Ag) (F005417)
- Additional newly identified E-W structural trend within the Slider region identified over ±450m of strike length returned assays up to 904g/t Ag, 6.5% Cu and 8.1% Zn (F005606)
- A similar mineralised structure, sampled over 450 m N-S also returned 383g/t Ag and 13.6% Cu (F005649)
Charlie, a skarn horizon covering a strike of approximately 900m, previously identified by state geologists has returned consistently high-grade polymetallic results adding further depth to the metal basket at Great Bear:
- 9.8% Cu 233g/t Ag 1.7% Pb 2.4% Zn (F005408)
- 8.3% Cu 135g/t Ag (F005407)
- 3.4% Cu 24g/t Ag 0.24% Tungsten (F005405)

From Troy Whittaker - Managing Director

“Well, this not something you see every day, let alone to find on surface during a maiden field program - possibly the highestgrade silver results published in recent history. It’s remarkable that the team has now delineated a total of six high grade Copper, Gold and Silver mineralised districts at Great Bear. Results to date have included massive, mineralised contents of 42.6% Cu, 42.2% Cu, 39.5% Cu, 38.2g/t Au, 29.7g/t Au and 716g/t Ag and, now, those results have now potentially been outshone by this silver discovery. To reel off, with consistency these results in a maiden campaign from around 15-20% of the overall Great Bear Project Area is great. If we are able to marry these results and structures up with the recently completed geophysics and prove depth potential we will be well placed for significant discovery.

Coming into this campaign, there was a high expectation given what historically had been identified at Great Bear. Pleasingly, we have not only exceeded those historical high grade assay results, but we have also extended mineralisation in all directions and in some cases into the kilometres as districts are identified. Amazingly, the 1.5 x 1.5 km Slider District remains underexplored. Given these results - there is a lot of upside for additional high grade silver structures to exist.” Troy Whittaker - Managing DirectorComing into this campaign, there was a high expectation given what historically had been identified at Great Bear.
