- The initial drilling campaign at Copper Ridge included a total of 2,229 metres (m) across 9 holes, and targeted surface anomalies covering an area over 1.5 km by 850 m identified during summer 2023 by prospecting. The drilling covered a 300 m by 300 m area in the western portion and 300 m by 150 m in the center portion of Copper Ridge.
- Mineralized veins were regularly intersected in all holes with additional mineralization observed locally in fractures and the host rock. Three different 20-metre corridors (core length) of gold-silver and copper-gold-silver were identified.
- During the 2023 field season, 80% of the outcrop samples collected were mineralized yielding results up to 78.9 grams per tonne (g/t) gold (Au), 4610 g/t silver (Ag) and 29.4 % copper (Cu) (see news release of February 21 st , 2024). The holes drilled during the 2024 program intersected similar mineralization down to 120 m depth along strike.
Chief Executive Officer, Michael Iverson , stated: "We are pleased to share the results from the first drilling campaign at Copper Ridge, which successfully intersected mineralized intervals that confirm the extension at depth of the veins sampled at surface during the 2023 field season. We were also pleasantly surprised to find mineralization in fractures and disseminated through the intrusive host rock between the veins which we seldom observe on surface due to the intensity of the weathering. This initial drilling shows a large mineralized system of which we've tested only a small portion and that remains open in all directions. The results and the geological information collected will be used to vectorize the plans for the next exploration season. With over $2.7M remaining in our treasury, we are well-positioned financially to continue advancing our projects in the year ahead."
The best results are compiled in Table 1, while Figure 1 illustrates the drill hole locations in relation to the 2023 surface sampling program and the interpreted zones. Figure 2 illustrates a cross-section of the drill holes in the central portion of Copper Ridge.
Holes CR-24-001 and CR-24-002 targeted the westernmost portion of the zone where metal zonation was suspected based on the surface sampling results (see Figure 1). The Company hypothesized that a gold-silver area was followed to the north by a copper-gold-silver one. Hole CR-24-001 appears to have straddled both zones, intersecting an interval of 0.51 g/t Au and 1.7 g/t Ag over 20.5 m between 124.2 and 144.7 m along the hole and a further interval of 0.47 g/t Au, 34.3 g/t Ag and 0.40 % Cu over 2.0 m between 239.3 and 241.3 m . Hole CR-24-002 intersected regularly mineralized veins, which appear to be part of the gold-silver trend.
Holes CR-24-003, CR-24-004 and CR-24-005 targeted the surface anomaly cluster in the central portion of the Copper Ridge system where it was initially discovered. All three holes intersected a wide mineralized interval, interpreted as part of the same zone now referred to as the Green Manalishi. Hole CR-24-003 returned 0.39 g/t Au, 9.9 g/t Ag and 0.39 % Cu over 19.1 m ; CR-24-004 returned 0.18 g/t Au, 8.4 g/t Ag and 0.39 % Cu over 21.0 m ; and CR-24-005 returned 0.12 g/t Au, 3.3 g/t Ag and 0.19 %Cu over 22.7 m . Several additional mineralized intervals were intersected in all three holes suggesting another zone, GM2 (see Table 1) and demonstrating continuity of the structures. Surface samples can be correlated to those two zones.
Holes CR-24-006, CR-24-007 and CR-24-008 were drilled east of the previous holes and were testing the same cluster of anomalies, but also the continuity at depth of the Green Manalishi zone. This zone was intersected in all three holes: CR-24-006 returned 0.10 g/t Au, 2.7 g/t Ag and 0.11 %Cu over 6.7 m ; CR-24-007 intersected 5.44 g/t Au, 21.1 g/t Ag and 1.89 % Cu over 1.5 m ; and CR-24-008 returned 1.6 g/t Au, 6.1 g/t Ag and 0.17 % Cu over 4.7 m . Another zone, GM3, was interpreted in all three holes (see Table 1). Hole CR-24-008 which targeted rocks further north intersected alternating granodioritic intrusions, feldspar porphyry dikes and mudrocks. The presence of the sedimentary rocks suggests either an irregular contact with the intrusion, which is known to exist more to the east, or they are xenoliths. The sediments are locally mineralized, especially in silver, with also amounts of copper, gold and zinc.
The six Green Manalishi zone intercepts reveal a mineralized corridor that is oriented north-south and dips to the east. It primarily consists of chalcopyrite, but also of pyrite and malachite, found within quartz veins, fractures and disseminated in the host granodiorite. The GM2 and GM3 zones are believed to have a similar orientation as the Green Manalishi zone.
Hole CR-24-009 tested the western part of the same anomaly cluster and intersected 20.5 m at 0.05 g/t Au, 4.3 g/t Ag and 0.05% Cu, which correlate well with the location of the surface anomalies and are interpreted as the shallow expression of the GM2 zone.
This initial drilling campaign, generated entirely by Prospect Ridge from a surface discovery, has revealed a powerful gold-copper-silver mineralized system that remains open in all directions. The Company is developing a strategy for the next field season to further advance this target and apply the newly acquired knowledge to the mineralized showings to the rest of the property.

Cautionary Statement
Outcrop samples are selective by nature and grades may not be representative of mineralized zones. The drilling results reported are core length, true thickness of the mineralized zones has not yet been determined.
Quality Control
The drilling was conducted by Driftwood Diamond Drilling Ltd. The NQ caliber core was measured, photographed, logged and sampled by Prospect Ridge's personnel. The holes were sampled from the start to the end.
Core samples were assayed for gold by standard 50 g fire-assaying with atomic absorption finish (Au-AA24), gravimetric finish (Au-GRA22) or 1000g metallic screening (Au_ SCR24 ) at ALS Canada in Terrace, British Columbia . The samples were also assayed for 36 metals from an aqua regia digestion with ICP-AES finish (ME-ICP41). For samples with over-limit results in silver, copper, lead and zinc, aqua regia with ICP finish was used (OG46 ore grade). A quality assurance/quality control program has been implemented and consists of inserting standards on a regular basis in the samples stream and blanks and sample duplicates in suspected mineralized zones.

About Knauss Creek Property
The wholly-owned Knauss Creek is approximately 35 kilometres northeast of Terrace, British Columbia , Canada. It is easily accessible by Highway 16 and a network of logging roads. It covers approximately 30 square kilometres and is contiguous to the Company's wholly-owned Holy Grail property.
Several gold, silver, copper, lead and zinc occurrences were discovered, previously. The most notable is the Dorreen mine where four adits were developed and, according to historical documents, approximately 700 tons of ore were mined out at an average grade of 16.8 g/t Au, 58 g/t Ag, 0.22% Cu, 2.1% Pb and 1.4% Zn from a quartz vein (not 43-101 compliant).
During the 2023 field season, the Company explored the Copper Ridge mineralized zone which has become the main focus for exploration on the property.
The southern tip of the Golden Triangle is located immediately northwest of Prospect Ridge's properties. The Bowser Lake and the Hazelton Groups hosting most of the deposits and mines in this area also underly the Knauss Creek and Holy Grail properties.
About Prospect Ridge Resources Corp.
