Cascadia Samples 9.01% Copper and Prepares for 2024 Diamond Drilling at PIL Property, British Columbia

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.

QA/QC

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.

ABSTRACT
A magnetotelluric (MT) study across the Red Lake greenstone belt of the western Superior craton, Canada, images a 50-km-long north-dipping conductor (<20 Ω·m) at 20–25 km
depth and subvertical conductors spatially correlated with crustal-scale shear zones and
large orogenic gold deposits. The conductors are interpreted to be the conductivity signature
of the deep crustal source of the auriferous fluids and pathways of the orogenic gold system. The geophysical results, supported by existing geochemical and fluid inclusion studies,
suggest that the Au- and CO2-rich fluids responsible for gold mineralization were released
by devolatilization of supracrustal rocks underthrust to mid- to lower-crustal levels during
subduction. This MT study links shallow gold mineralization to a deep crustal source region,
demonstrating the connection between a crustal suture zone and the formation of orogenic
gold deposits in an Archean greenstone belt.

 

American Copper Development Completes 134 line-km Titan 160 DCIP and MT Survey Over the Lordsburg Property, New Mexico

Vancouver, British Columbia–(Newsfile Corp. – January 18, 2023) – American Copper Development Corporation (CSE: ADCX) (“ACDC” or the “‎‎Company”) is pleased to report preliminary results from a 134 line-km 3D Titan 160 DC resistivity/induced polarization (DCIP) and Magnetotellurics (MT) survey. The survey was completed across 16 lines (13 N-S and 3 E-W) by Quantec Geoscience over the Company’s flagship Lordsburg property in southwestern New Mexico (see map in appendix).

The purpose of the survey is to provide property-wide deep chargeability, resistivity, and magnetotelluric information at the Lordsburg property with the intent to help identify porphyry and/or skarn style mineralization targets. The DCIP provides information to depths of 700m and greater with the MT resistivity providing information to depths of up to 2km. Quantec conducted this high-resolution survey between August 2022 and January 2023. The Company is currently working with our contractors on 3D data inversions of both the DCIP and MT surveys and expect to have those results completed by February.

 

 

Geophysical imaging of the Healy property was achieved with deep-seeing Titan™ IP and MT surveys (induced polarization and magnetotellurics), transecting five kilometers across the three target areas where drilling was conducted. The surveys were carried out towards the end of the field season due to contractor availability. The IP and MT surveys, which imaged up to 800 meters and 4 kilometers depth respectively, support the presence of shallowly dipping, east-verging architecture with mineralisation occurring along low angle thrust faults and steeper cross-cutting fault corridors. Broad zones of disseminated sulfide and strong alteration are well-defined in the chargeability and resistivity data with zones of combined high chargeability and low resistivity (high conductivity) correlating well with mineralised intercepts from the 2021 drill program. The imaging of additional strongly conductive and chargeable zones, between drilled prospects, highlight significant exploration targets which warrant follow-up drill testing.

Quantec Geoscience Completes TITAN MT Deep-Penetrating Geophysical Survey at La Virginia

  • Drilling at Paredones zone is complete, with first results now received
  • Prospecting activities continue to advance La Colmena, north of El Rubi, and return encouraging surface samples ranging up to 8.31 g/t gold and 90 g/t silver from chip sampling at the southern extension of El Molino Zone

VANCOUVER, BCApril 8, 2022 /CNW/ – Silver Viper Minerals Corp. (the “Company” or “Silver Viper“) (TSXV: VIPR) is pleased to provide an update on exploration activities within the La Virginia Silver-Gold Project, located in Sonora, Mexico. Exploration efforts since the release of Silver Viper’s Maiden NI 43-101 gold-silver mineral resource estimate have continued to advance with exploration drilling at El Rubi and expansion of mapping and sampling coverage across the project area. Recent drilling has been performed at the Paredones Zone on the eastern structural/mineralized trend. Quantec Geoscience contractors have now completed data collection for a 31 line-kilometre Magnetotelluric geophysical survey covering approximately 610 hectares (1,500 acres). Final deliverables from the survey are expected in the coming weeks.

Silver Viper had engaged Quantec Geoscience to execute a TITAN-MT deep-penetrating geophysical survey centered on the El Rubi Deposit, Paredones and El Molino target areas. The survey is expected to greatly assist in targeting for deeper portions of the mineralized system. The TITAN Magnetotelluric (“MT“) survey is capable of acquiring information from depths in excess of 1,500 metres below surface. In anticipation of the survey, drilling recently focused on probing of prospective mineralized structures and trends, most recently the Paredones area on the eastern trend sub-parallel to that hosting El Rubi.

Silver Viper’s President and CEO Steve Cope states “Quantec has shared preliminary data from the first lines of the MT survey.  We expect the geophysics to help in refining drill testing of existing zones and to reveal new deeper unexposed targets. Once the data is processed, we anticipate identification of additional prospective targets, comparable in size to El Rubi. Preliminary data is already showing potential new targets that were previously unknown.

The exploration team has reviewed preliminary 2D imaging from the first of the MT survey lines and believe the method will be very effective at La Virginia. The company eagerly awaits final deliverables expected in the coming weeks.

Prospecting work continues along the El Rubi trend and the adjacent El Molino trend. Advances have been made at the La Colmena, Paredones and El Molino South prospect areas.  These early-stage prospects host outcroppings of silicified hydrothermal breccias and quartz veining, similar to breccias and veining seen in the El Rubi area. In addition to the geophysical survey, current work includes rock chip sampling and mapping.

Targeting San Pablo Porphyry with 15,000 Meters

Toronto, Ontario–(Newsfile Corp. – February 7, 2022) – Andean Precious Metals Corporation (TSXV: APM) (OTCQB: ANPMF) (“Andean” or the “Company“), a leading Latin American precious metals producer, is pleased to announce the launch of a 15,000 m, Phase Two drill program focused on the San Pablo porphyry target identified in the recently completed Titan geophysical survey.

Our Phase Two exploration program will test a porphyry target at our San Pablo Gold Project that was identified in our recently completed Titan Geophysical survey. We have budgeted 15,000 meters for this purpose.” Mr. Griffiths went on to say, “I am encouraged by the scope of opportunity that exists for Andean to grow organically in Bolivia. Exploration is a key element of this growth, complementing our San Bartolomé mine life Expansion Study and the continued extension of our government contracts.”

Twelve diamond drill holes were completed at San Pablo in 2021 for a total of 3,580 m, as reported in the press release of November 30, 2021. The highlight was an intersection of 53.8 m grading 1.17 g/t Au from 211 m depth in hole SP21-01. All twelve holes encountered anomalous gold throughout their lengths.

Quantec Geoscience subsequently carried out a 9-line, 20.3 line-kilometers, Titan 24 deep induced polarisation survey (“DCIP”) and magnetotelluric survey (“MT”) at San Pablo that was completed in December. On many lines the DCIP shows a thick, very conductive layer close to the surface that limits the depth of penetration. The magnetotelluric survey, which is a passive method that uses the earth’s natural electromagnetic field as the source field to image subsurface resistivity structure, achieved depths of investigation of about 1,200 m. The survey detected very low resistivity anomalies at depth that are interpreted to be altered porphyry intrusions. These will be tested in the forthcoming Phase Two drill program. The holes are being targeted on the basis of low resistivity, high chargeability which may be due to sulphides with associated gold, and geology.

VANCOUVER, B.C., July 20, 2021  Tectonic Metals Inc. (TECT: TSX-V; TETOF: OTCQB; T15B: FSE) (the “Company” or “Tectonic”) today announced the commencement of a deep-penetrating TITAN-160 (“TITAN”) ground-based Geophysical Survey (the “Survey”) designed to specifically target multiple Pogo-like gold-in-soil anomalies situated on the Company’s Tibbs Gold Project (“Tibbs”), located in Alaska’s Goodpaster Mining District, 35 kilometres (“km”) east of Northern Star Resources’ Pogo Gold Mine. The Company engaged Quantec Geoscience Limited to carry out the Survey at Tibbs to transect the entirety of the structural corridor, which controls gold mineralization at the property. TITAN is a unique survey that employs two separate geophysical surveys: DC Resistivity and Induced Polarization (“DCIP”) and Magnetotelluric (“MT”) and provides DCIP resistivity and chargeability sections at depths of up to 750m, with MT collected to depths of 1,500m and greater.

 

Tibbs Gold Project – TITAN Survey Lines

TITAN-160 Survey – Technical Details
Four TITAN lines 4,000m long and spaced approximately 1,000m apart are planned at Tibbs. Dipoles are spaced at 100m along each line, with MT sites spaced at 200m, to provide data coverage to significant depths (DCIP to approximately 750m depth; MT resistivity to approximately 4,000m depth). The Survey is expected to be completed in the latter half of July.

 

TORONTOJune 11, 2021 /CNW/ – Orefinders Resources Inc. (“Orefinders” or the “Company”) (TSXV: ORX) is pleased to announce the completion of a DCIP-MT ORION SWATH ground-based Geophysical Survey (“Survey”) on its McGarry Gold Project (“McGarry”). McGarry is adjacent to the Kerr Addison Mine that produced approximately 11 million ounces of gold before closing in 1996.

The initial 2-D modeling of the Survey data has shown significant IP (Induced Polarization) and MT (Magnetotelluric) anomalies associated with the Larder-Cadillac Fault Zone between the McGarry headframe and the Barber-Larder open-pit and also at other less explored target areas at McGarry (Figure 1).

“This sort of survey, combining quasi 3-D IP and deep-penetrating MT technologies has never been conducted on McGarry. This approach is aimed at delineating new exploration drill targets that could lead to new gold discoveries on a highly prospective project along the Larder-Cadillac Fault Zone,” said Keith Benn, Orefinders Vice President of Exploration.

The Survey was designed to gather high-resolution data at depth that will be key to identifying ‘under cover’ exploration targets, i.e., potential ore bodies that do not reach the surface. Subsequent 3-D modeling of this geophysical data set along with machine learning applied to all available data for McGarry will allow the Company to prioritize exploration targets for a drilling program later in 2021.

 

Scope of Project:

Laurentian University’s Mineral Exploration Research Centre (MERC) is leading a geophysical survey in the Timmins and Cochrane area from October 7 to November 15, 2020.

The goal is to advance geoscientific knowledge about the underlying geologic architecture, structures, and mineral resource potential of the Earth’s crust approximately 30 kilometres below the surface. 

The project is part of MERC’s $104 million Metal Earth project, which is Canada’s most extensive exploration research program and involves a consortium of industry partners. 

Quantec Geoscience will use electromagnetic technology, specifically magnetotelluric (MT) and audio magnetotelluric (AMT) instruments, to survey selected stations within a corridor of approximately 130 kilometres by 50 kilometres.

The corridor stretches from Highway 11 in the north to 50 kilometres south of Timmins. Surveyors will be active in some residential areas. 

High-resolution AMT surveys in the Timmins gold camp are made possible with consortium partner support. Newmont Corp is funding surveying from Tisdale to Matheson townships. International Explorers and Prospectors Inc. and Lake Shore Gold (a subsidiary of Pan American Silver) are funding surveys from Loveland to Thorneloe townships, west of Timmins. 

The new survey adds data to previous seismic and ongoing MT and AMT surveys conducted through the Metal Earth project in Ontario and Quebec. Seismic surveys were completed as part of the Discover Abitibi project, managed by the Timmins Economic Development Corporation, in 2004. MT and AMT surveys were not previously conducted in the planned survey area. 

Toronto, Ontario – August 6, 2020 – Generation Mining Limited (TSX:GENM) (“Gen
Mining” or the “Company”) is pleased to announce the preliminary results from its SPARTAN
Magnetotelluric (“MT”) survey over a portion of the Marathon Deposit resource including the
W Horizon and structures to the west of the deposit which are believed to have provided a
favourable environment for enriched palladium mineralization. Analysis of the MT data has
identified one prospective target which consists of a discrete, previously undrilled, conductive
MT anomaly situated at a vertical depth of approximately 650 meters downdip and immediately
west of the Marathon Palladium Copper Deposit (Figure 1). The anomaly is at a depth beyond
the depth penetration capabilities of a preexisting airborne electromagnetic survey of this area
(completed by a previous operator) and most importantly the anomaly is more conductive than
Marathon Palladium Copper deposit mineralization. Consequently, the anomaly constitutes a
high priority drill target given its coincidence with the presumed down dip extension of the
Marathon Series Gabbros which constitute the feeder zones to, and are the host of, PGM-Cu
mineralization at the Marathon Deposit.
