Cascadia Samples 9.01% Copper and Prepares for 2024 Diamond Drilling at PIL Property, British Columbia
January 9, 2024
January 9, 2024 – Vancouver, BC – Cascadia Minerals Ltd. (“Cascadia”) (TSX-V:CAM) is pleased to provide results of the 2023 exploration program at the PIL Property, located in the prolific Toodoggone porphyry copper-gold and epithermal precious metals district of northern British Columbia, Canada. Work in 2023 included a TITAN deep induced polarization (“IP”) geophysical survey at the PIL South target, as well as prospecting and mapping focused primarily in the underexplored northeastern portion of the property, at the Spruce target.
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 Graham Downs, Cascadia’s President and CEO. “The prospecting results from the recently identified Spruce target are also very exciting. We have now defined a 2.6 km mineralized trend in this area with alteration profiles suggestive of porphyry mineralization. We will continue to systematically advance Spruce in 2024, with geophysics, surface work, and drilling if warranted.”
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.
Property Geology and Mineralization
The 151 km2 PIL Property is located in the heart of the 90 x 20 km northwest-trending Toodoggone district in northern British Columbia, within the eastern part of the Stikine Terrane. The Stikine Terrane is juxtaposed against the Quesnel Terrane by the 1,000+ km long, deep seated, crustal scale strike-slip Teslin-Thibert fault approximately 8 km northeast of the property boundary. Stikine and Quesnel Terranes are characterized by similar Late Triassic to Early Jurassic volcanic-plutonic arc complexes that host numerous porphyry copper-gold-molybdenum mines, deposits and prospects including Red Chris (Newmont Mining), Galore Creek (Teck/Newmont), Kemess (Centerra Gold), and Mount Milligan (Centerra Gold). Numerous epithermal gold-silver projects are also found in the region, including Brucejack (Newmont Mining), Ranch (Thesis Gold) and Lawyers (Thesis Gold).
The Toodoggone district is underlain by volcanic and sedimentary rocks of the Early to Middle Jurassic Hazelton Group and the coeval Early Jurassic Black Lake Plutonic intrusive complex. There is a prominent northwest-trending regional structural fabric with the strata in the Toodoggone disrupted by several steeply dipping normal faults, strike-slip faults and thrust faults.
The Property is under option from Finlay Minerals Ltd., and Cascadia has the ability to acquire a 70% interest in the project by making a series of staged payments and work expenditures. For more details on the Property, please visit our website at www.cascadiaminerals.com.
Cascadia is a Canadian junior mining company focused on exploring for copper and gold in the Yukon and British Columbia. Cascadia’s flagship Catch Property in the Yukon hosts a brand-new copper-gold porphyry discovery where inaugural drill results returned broad intervals of mineralization, including 116.60 m of 0.31% copper with 0.30 g/t gold. Catch exhibits extensive high-grade copper and gold mineralization across a 5 km long trend, with rock samples returning peak values of 3.88% copper and 30.00 g/t gold.
In addition to Catch, Cascadia is conducting exploration work at its PIL Property in British Columbia and the Sands of Time and Rosy properties in the Yukon, as well as evaluating additional regional opportunities. Cascadia has approximately 37 million shares outstanding and its largest shareholders are Hecla Mining Company (19.6%) and Barrick Gold (7.5%).
Analytical work for samples was completed by ALS Canada Ltd., with sample preparation in Kamloops, BC, and geochemical analyses in North Vancouver, BC. Rock samples were fine crushed before a 250-gram split was pulverized to better than 85% passing 75 microns. Gold was determined for core samples by the Au-AA23 procedure which involves fire assay preparation using a 30-gram charge with an atomic absorption spectroscopy finish. Multi-element data for 48 elements was determined for by the ME-MS61 procedure, which involves a four-acid digestion followed by inductively couple plasma-atomic emission spectroscopy (“ICP-AES”) and inductively coupled plasma-mass spectrometry (“ICP-MS”). Overlimit values for copper, silver, lead and zinc were determined using the ME-OG62 procedure, which involves a four-acid digestion followed by ICP-AES analysis.
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.
Results referenced in this release represent highlight results only. Below detection values for gold, silver, copper, lead, zinc and molybdenum have been encountered in drilling, rock and soil samples in these target areas.

Calgary, Alberta–(Newsfile Corp. – November 22, 2023) – Copper Fox Metals Inc. (TSXV: CUU) (OTCQX: CPFXF) (“Copper Fox” or the “Company”) and its wholly owned subsidiary, Desert Fox Mineral Mountain Co., are pleased to announce the results of the deep penetrating geophysical survey utilizing Quantec’s ORION 3D Swath DCIP configuration on its 100% owned Mineral Mountain project (the “Project”) located approximately 16 miles northeast of Florence, Arizona. Highlights of the survey are set out below:
- A northeast trending open-ended positive (>18mrad) chargeability/resistivity anomaly measuring approximately 3,200 meters (‘m’) long by 1,200 m wide has been identified.
- The chargeability/resistivity signature is like that which would be expected in the oxidized/supergene zone above the hypogene zone of a porphyry copper system in Arizona.
- A 1,200 m long by 900 m wide portion of the larger chargeability/resistivity anomaly comes to surface in an area of the property with quartz vein/veinlet/fracture hosted secondary copper (chrysocolla, malachite, chalcocite) and molybdenum mineralization in sericitic/potassic altered porphyritic quartz monzonite and granodiorite.
- An additional 80 mineral claims (1,653 acres) have been added to the Project to cover the interpreted extension of the northeast trending open-ended positive chargeability/resistivity anomaly and a mineralized Laramide intrusive.
Elmer B. Stewart, President, and CEO of Copper Fox, stated, “The results of the IP survey are consistent with the current geophysical model for the oxidized/supergene enriched portion of a Laramide age porphyry copper system in Arizona. The strong positive correlation between the various geoscientific data has identified a near surface drillable target measuring approximately 1,200 m long and 900 m wide that transitions at depth to a significantly larger chargeability signature consistent with the geological/exploration model developed for the Mineral Mountain project.”
The Mineral Mountain project covers a copper-gold-molybdenum porphyry system characterized by a copper-magnetite mineral association that has been subjected to weathering/oxidization/supergene enrichment, a process commonly observed at porphyry copper systems in Arizona. The porphyry copper deposits in the Safford and Ajo Mining Districts of Arizona are being used as geological/exploration models for the Project. The porphyry copper footprint at Mineral Mountain is located on the eastern side of the Laramide intrusive and is interpreted to dip to the east and to the north under the PreCambrian rocks consistent with the location of the recently defined chargeability signature.
Recent investigation of the geophysical characteristics of porphyry copper systems in Arizona shows that the oxidation/supergene processes that affected these porphyry copper systems have altered the petrophysical properties of the mineralization and host rock resulting in lower chargeability and increased resistivity signatures within the oxidation/supergene zone of porphyry copper deposits.

The 2023 geophysical survey has outlined a northeast trending open-ended 3,200 m long by 1,200 m wide chargeability (+18mrad contour) anomaly. Based on the +15mrad chargeability contour, the western, southern, and southeast edges of the anomaly have been defined. The anomaly remains open to the northeast.

The lower chargeability/increased resistivity signature is similar to the recent geophysical model of Laramide age porphyry copper deposits in Arizona. Figure-2 and Figure-3 show the chargeability and resistivity pseudo sections for L-2000 that crosses the 1,200 m by 900 m chargeability/resistivity anomaly. The strength of the chargeability signature increases with depth and is interpreted to represent the primary hypogene sulphide zone of a porphyry system.

Rationale for Land Acquisition
The Mineral Mountain project is located within a northeast trending, regional scale, porphyry copper belt that extends from the Ajo porphyry copper district in the west to the Miami-Globe porphyry copper district in the east and hosts some of the largest porphyry copper deposits in Arizona including Santa Cruz and Resolution. The Project is located approximately 25 kilometers (‘km’) east of Florence, Arizona between the Florence and Resolution porphyry copper deposits.
The recently acquired lands covers:
- Four Laramide age quartz monzonite plugs and several Tertiary age porphyritic granodiorite dikes, interpreted to represent the continuation of the Mineral Mountain intrusive complex to the northeast.
- The results of the 2023 geophysical survey indicate that the chargeability/resistivity anomaly associated with the copper mineralization at Mineral Mountain extends to the northeast into the recently acquired mineral claims.
- The largest of the quartz monzonite plugs host extensively oxidized/leached porphyry style quartz veins, quartz veinlets and fractures containing secondary copper minerals (chrysocolla, malachite, chalcocite) and molybdenite.
- The 2022 airborne magnetic and radiometric survey identified a buried positive magnetic feature interpreted to represent a potassic altered (due to magnetite) late stage intrusive underlying the largest Laramide age intrusive.
Geophysical Survey Procedures
The ORION 3D SWATH DCIP survey completed by Quantec Geoscience USA Inc. was centered over the Laramide intrusive and measured (employing a pole-dipole array configuration) the DCIP signal on 9 survey lines. The survey mesh covered an area of approximately 3.2 km x 3.6 km using a 25 m cell size in the X and Y directions to cover the electrode array zone (core mesh). Padding cells covering ~3.35 km in each horizontal direction were added to extend the core mesh. A homogenous half-space of ~ 750 ohm-m was used as a starting model for DC inversion. The IP inversions were completed with use of the sensitivity matrix calculated from the calculated 3D conductivity model.
The 2D DC and IP inversions were carried out using the UBC DCIP2D inversion codes (Oldenburg and Li, 1994) to produce depth sections of DC resistivity, DC-referenced IP chargeability and HS-referenced IP chargeability to a depth of investigation of 750 m to 800 m. The 3D inversion of the DC and IP data was completed using the UBC 3D inversion codes (Li and Oldenburg, 2000). The full set of 3D Tx-Rx measurements were merged into a single data set and modeled in 3D to produce 3D resistivity and DC-referenced chargeability models.

October 30, 2023 – Toronto, Ontario – Palladium One Mining Inc. (TSX-V: PDM, OTCQB: NKORF, FRA: 7N11) (the “Company” or “Palladium One”) is pleased to announce it has discovered a large MT resistivity anomaly on the Tyko I property (Figure 1 and 2) which forms part of the larger Tyko Nickel – Copper Project, in Ontario, Canada. The MT resistivity anomaly is coincident with the high-grade West Pickle Zone and extends eastward toward the RJ Zone suggesting that they form one continuous mineralizing system.
- 2023 diamond drill program is underway at Tyko
- A 1,600 meter long MT resistivity anomaly has been discovered which extends from the high-grade West Pickle Zone toward the interpreted Chonolith / Feeder Dyke structure
- MT Anomaly coincident with multiple Cu and Ni in soil anomalies
- Mag, MT and soil anomalies suggest West Pickle and RJ Zones form part of one large mineralizing system
President and CEO, Derrick Weyrauch commented, “We are very pleased to announce positive results from the first MT survey on the Tyko Project that indicate a strong MT resistivity anomaly extending from our high-grade West Pickle zone toward multiple copper and nickel in-soil anomalies associated with the interpreted Chonolith / Feeder Dyke target. Tyko’s fall diamond drill program has commenced and is currently on track.”
The MT survey represents the first deep penetrating geophysical survey to be conducted on Tyko. The survey was undertaken by Quantec Geoscience using the SPARTAN MT system which has the potential to detect both high-grade massive nickel sulphide, as that found at the West Pickle zone, and blebby to disseminated sulphide as found at the RJ zone. The MT survey targeted a highly prospective strike length of 2,800 meters (Figure 2) between the West Pickle and RJ Zones covering several highly anomalous Cu and Ni soil anomalies and associated magnetic highs (see press release August 22, 2023).
