PIL 2023 Exploration Summary
- Deep IP survey at the PIL South target identified a classic porphyry signature below shallow historical drilling that intersected typical high-level pyrite mineralization and alteration;
- The IP survey signature underlies a 2.5 x 2.0 km gold-copper ± molybdenum soil and rock sample anomaly at surface;
- Prospecting at the Spruce target identified significant copper, silver and molybdenum samples along a 2.6 km trend;
- Spruce rock sample highlights include 9.01% copper with 212 g/t silver and 0.26 g/t gold in float, and 3.75% copper with 101 ppm molybdenum in outcrop; and
- Planning is underway for 2024 exploration, including diamond drilling at PIL South in 2024 to test the porphyry target at depth and geophysics and mapping to prepare Spruce for drilling.
"We are very encouraged by the deep IP survey at the PIL South target as it returned compelling indications of porphyry copper mineralization at depth, beneath historical shallow drilling. We plan to undertake our first diamond drill program at PIL this summer, focusing on testing PIL South at depth," said

PIL South TITAN IP Survey Results
A TITAN deep IP geophysical survey was conducted at the PIL South target in 2023, in an area with strong surface mineralization, limited historical drilling, and a strong response from a shallower conventional IP survey completed in 2022. Two perpendicular TITAN IP lines were completed, totaling 4.8 line-km (Figure 2).
Results of this survey are suggestive of the potential for a buried porphyry target underneath the shallow historical drilling. The chargeability response exhibits a broad zone of very high-chargeability around a deeper zone of moderate chargeability, suggestive of a pyrite halo around the core of a porphyry system (Figure 3) at the 1,200 m elevation level. The resistivity response shows a core zone of moderate resistivity with moderate chargeability values that could represent the potassic core (Figure 4).
Three shallow historical drillholes were completed by a previous operator at this target in 2003, with no significant intercepts of copper mineralization. Core from these holes were reviewed in detail this season and exhibits high-level alteration signatures (propylitic to sericite alteration), as well as zones of significant pyrite, and short intervals of anomalous copper and gold. This supports the interpretation of the IP signature, suggesting the presence of a pyrite shell – intersected by historical drilling – potentially adjacent to the potassic core of a porphyry that has never been drill tested.
Cascadia plans to drill-test this hypothesized potassic core in 2024, embarking on its first diamond drilling campaign at the PIL property.
Prospecting and Mapping Results
Fieldwork in 2023 included the collection of 420 soil samples and 186 rock samples. Exploration was focused on the Spruce and PIL South areas, with expansion of soil grids at both targets (Figure 1). Contour sampling and prospecting was also completed in various underexplored areas between the two targets.
Rock sampling at Spruce identified mineralization in float and outcrop across a 2.6 km trend northwest of the original 2022 discovery outcrop, in an area that has seen no historical exploration. Grab samples returned results including 3.75% copper with 101 ppm molybdenum in outcrop, 2.07% copper in outcrop, and 9.01% copper with 212 g/t silver and 0.26 g/t gold in talus (Figure 5). The alteration assemblage and trace element signature of samples in this area are strongly suggestive of porphyry style mineralization at depth. Given the extensive nature of mineralization at Spruce, planning is underway for follow-up work in 2024.
Soil sampling results extended the known PIL South anomaly further to the east, and identified a new area of potential mineralization 3 km south of the Spruce target (Figure 1). These areas will be further evaluated in 2024.

Analytical work for samples was completed by
Soil samples were dry-screened at 180 micron, with analysis conducted on the fine fraction. Soil samples were analyzed for gold and 50 other elements by the AuME-TL43 procedure which involves aqua regia digestion of a 25-gram split with an ICP-AES and ICP-MS finish.
