Prospect Ridge Resources Corp. (CSE:PRR) released visual drill core observations and portable X-ray fluorescence (pXRF) readings from the final four holes of a 10-hole diamond drilling program at its 100%-owned Camelot copper-gold project in British Columbia’s Cariboo Mining District. The company reported that copper-bearing mineralization was visually identified and supported by pXRF readings in all four of the latest holes.

The 2,010-metre drill program was completed over 21 days, using eight drill pads and targeting a 1.7-kilometre-long geochemical and geophysical trend on the property. According to the company, all drill sites, access roads, and trails have now been rehabilitated, with only some reseeding work still to be completed.

The final four drill holes, CAM25-007 through CAM25-010, were completed from three sites on the northeastern section of the trend. Combined, they represent 903 metres of drilling, with the most northeastern hole (CAM25-009) collared 1,740 metres from the first hole drilled in the program, highlighting what the company described as the scale of porphyry potential at Camelot.

The 2025 program was the first to drill test the target area, described as being covered by till and selected based on copper-in-soil anomalies, magnetic highs, and chargeability readings. These targets were pursued using an alkalic porphyry exploration model.

pXRF and Visual Logging Results

Prospect Ridge stated that all of the four latest holes showed disseminated pyrite and chalcopyrite, supported by pXRF readings. The company said mineralized intervals were linked to overprinting alteration and vein sets, particularly in CAM25-009, where multiple stages of porphyry-style alteration — including moderate to strong K-feldspar, albite, and epidote alteration — were recorded.

Eight of the 10 drill holes were stopped at around 200 metres to test multiple targets, although pyrite and chalcopyrite were observed at the bottoms of most holes. CAM25-004 ended at 102 metres, while CAM25-010 was extended to 301 metres to test a deeper geophysical target.

Samples from CAM25-007 and CAM25-009 were sent for rush assays. Prospect Ridge noted that pXRF data from the first six holes showed a positive correlation between sulfide content and chargeability values, leading to adjustments in the collar locations for later holes.

The company also reviewed partially assayed historic drill core from LL22-001, collared near CAM25-009 but drilled in a different direction. Only three out of every fifteen metres in the bottom 192 metres had been previously assayed. According to the company, oxidation improved visibility of chalcopyrite in the older core, prompting plans to sample the previously unassayed material.

Target Areas

Three main geophysical target areas were tested during the program — Alpha, Bravo, and Echo — each defined by coincident chargeability and magnetic anomalies.

Alpha Target:
Four holes tested this zone. CAM25-008 intersected altered monzodiorite and diorite intruding andesite, hosting 0.5–5% fine pyrite and trace chalcopyrite. CAM25-010 intersected altered andesite intruded by diorite, monzodiorite, and monzonite, containing 1–5% pyrite and rare chalcopyrite. Earlier-reported results from CAM25-005 and CAM25-006 included trace to weak chalcopyrite, quartz veinlets, and pyrite veining.

Bravo Target:
CAM25-007 targeted this anomaly and encountered altered monzonite intruding andesite with 1–3% pyrite and fine chalcopyrite detected by pXRF. Rare chalcopyrite in quartz veins was also noted.

Echo Target:
CAM25-009 tested a chargeability high adjacent to a moderate magnetic anomaly and reached 201 metres. Visual logging recorded the highest chalcopyrite concentrations in sections corresponding to the chargeability anomaly, supported by pXRF copper readings. The hole encountered volcanic rocks and felsic dikes with potassic alteration and chalcopyrite mineralization. No significant felsic intrusive body was intersected, although the company noted similarities to porphyry-style deposits without obvious causative intrusions.

A cross-section for CAM25-009 showed lithology, chargeability modeling, and pXRF copper histogram values, though Prospect Ridge cautioned that pXRF spot analysis is qualitative and not a substitute for laboratory assays.

Portable XRF Use

Portable XRF was used to identify copper in drill core where alteration hindered visual detection. Spot samples were taken on approximately 0.5 cm² areas at one-metre intervals. The company stated that while the method is reliable for copper detection, it is less representative than wet chemical assays and should be used as a qualitative indicator. Certified reference materials were occasionally measured to confirm accuracy, and the results were integrated into 3D modeling.

Camelot Property Context

The 2,646-hectare Camelot property is located about 65 kilometres east of Williams Lake, B.C., within the Quesnel Terrane, an area known for copper-gold and copper-molybdenum porphyry deposits. It lies 34 kilometres southeast of the Mount Polley mine and 13 kilometres northeast of the Woodjam project.

The project area benefits from local infrastructure and year-round access. Earlier exploration outlined a 1,700-by-500 metre magnetic and chargeability anomaly beneath shallow cover. The property is centered on the Lemon Lake stock, a multi-phase pluton intruding volcanic rocks. Alteration and minor pyrite-chalcopyrite mineralization are linked to monzonite intrusions.

Program Management and Oversight

The drill campaign was conducted from pads built near logging roads and fire breaks to reduce surface disturbance. All coordinates for the drill collars were reported using UTM NAD83 Zone 10.

Equity Exploration Consultants Ltd. managed the exploration program. Core logging took place under on-site supervision by registered geoscientists. Dorado Drilling Ltd. served as drill contractor.
