Excellent Metallurgy Results for Redonda
December 2, 2024 - Vancouver, British Columbia. Stamper Oil & Gas Corp. ("Stamper" or the "Company") (TSX V: STMP; FSE: TMP2) Is thrilled to share the excellent metallurgical test results by Process Mineralogical Consulting Ltd. (PMC Labs) from the Redonda Copper Molybdenum and Rhenium drill program.
The main Cu- and Mo-bearing phases in the Master Composite are chalcopyrite and molybdenite, respectively. This material reports 0.33 wt.% Cu, 5.74 wt.% Fe, and 0.33 wt.% Mo, accompanied by 2.3 ppm Ag.
Flotation test work suggests that the initial samples and exploratory test work are successful in producing copper recoveries ranging from 94.7% to 96.9% and molybdenum recoveries ranging from 92.2% to 95.6% after 5 stages of rougher flotation tests.
The metallurgical program was coupled with detailed mineralogical investigation on the material provided, aiming at identifying the main mineral phases that make up the ore. This was achieved by carrying out size-by-size Automated Scanning Electron Microscopy (SEM)-based mineralogical characterization (AutoSEM), providing quantitative information on the mineral phases and their abundance (modal composition), particle and grain size distributions, mineral associations and liberation characteristics. The acquired mineralogical information was then employed to support the design of the metallurgical tests and interpret the results.
The project was carried out in a two-stage approach. The first stage was based on the size-by-size mineralogical characterization of the ore, followed by metallurgical testing through the analysis of grinding properties and flotation trials.
A Bond Work Index of 15.17 kWh/ton for the Master Composite indicates that the material falls within the moderate hardness range. This value is comparable to typical BWi values for copper and copper-molybdenum ores, which generally range between 10 and 20 kWh/ton.
To achieve a P80 of 75 mum, the target grinding size for optimal liberation (as established in the Size-by-Size Mineralogical Characterization results), a stage-grind calibration test was conducted on the Master Composite. The test results indicated that 108 minutes of grinding would be required to reach a P80 of 74 mum.
Comments from President and CEO Bryson Goodwin;
"The preliminary findings from RED 23-03 have left my team and me thoroughly impressed. Upon reviewing the data, the significance of the results.
Additionally, we achieved significant near surface values, ranging from 3.1 meters to 18.2 meters of 0.611% CuEq. This result further strengthens our confidence in the conclusions drawn from our research.
The discovery that a 200-meter hole is "almost fully mineralized" while yielding better than anticipated results is a confirmation of our acquisition of Redonda. The Stamper team anticipated positive outcomes, but was pleased to discover this wide of an intercept of mineralized core.

The copper equivalent calculation utilizes the standard equation and is based on current spot metal prices of copper at more than US $4.00 per pound, Re at $65 per ounce and molybdenum at $30.00 per pound. Recoveries are set at 92.7% for Cu and 92.2% for molybdenum for the purpose of the copper equivalent calculation based on metallurgical test results available. Cu Eq is used for illustrative purposes only and does not imply that the metals are economically recoverable.
The currently known highest grade copper-moly zone and associated breccias extend over a defined northerly horizontal length of over 600m, a width of at least 500m and a vertical extent of 300m. This is higher grade, potassic altered centre of mineralization is composed of variable density of dark mafic-rich fragments. Higher grades are clearly related to abundance of dark fragments in vugs and heavy chalcopyrite/molybdenite and pyrrhotite replacement.
However, some high-grade copper/MoS2 is also associated with the density of quartz stockworks and fracture filling. The locus of magmatic-hydrothermal multi-phase intrusives and brecciation associated with mineralization is distinct from the surrounding Coast Plutonic Complex although current level of mapping has not well defined the contact relationships. The multi-phase system is clearly younger than the enclosing Coast Plutonic rocks.
The very large breccia-agmatite body to the northeast is sparsely mineralized on surface but has not been tested by drilling. Previous operators suggest that the focus of mineralization may occur at depth to the northeast as interpreted by the magnetic signature.
The company has engaged an Airborne magnetics and radiometrics survey to define the potassic core zone.
This program is currently permitted. A new Notice of Work (NoW) has been filed in 2023 to expand the currently permitted program which is still under review.
The mineralized zones are open to the north. A separate old road system 1.0km to the northwest will be investigated in 2024 for possible extensions of the mineralized zone.
The mineralized zone is open to the south but may plunge to the south (under the Coast Plutonic Complex. Some future drilling is warranted along roads to the south after airborne geophysics is completed.
The current results allow a re-interpretation of the geology and mineralization. The entire mineralized area is a series of multi-phase magmatic-hydrothermal breccias.
About Redonda:
The project comprises 9 claims totaling 2746.46ha and is located 40km northeast of Campbell River, BC. Redonda is easily accessed with year-round regularly scheduled barge service out of Campbell River via Marinelink. Access from Redonda Bay is by 5km of recently upgraded logging road. Logging is ongoing and assures a well-maintained complex of forest service roads across the claims. Work proceeded in 2021 under a Letter of Support from the Klahoose First Nation within their Traditional Territory and Free Use Permit, Drill Permit and IP Exemption from the Ministry of Energy, Mines and Low Carbon Innovation (EMLI).
The regional setting of the Redonda property is part of the Coast Suture Zone between the Wrangellia Terrane and the Coast Plutonic Complex. In the claims area, Early Cretaceous dioritic intrusive rocks of the Coast Plutonic Complex have been intruded by at least three later intrusive units, including a quartz plug, a 60 to 90 meter wide hornblende dike which is locally brecciated over its 650 meter exposed length and several smaller feldspar dikes which cut dioritic rocks near the southwest margin of the hornblende dike. Higher concentrations of copper-molybdenum mineralization are closely associated with the hornblende dike, particularly in areas where it has been brecciated. The geological setting of the mineralization on the Redonda mineral claims share a number of features similar to those observed at the OK Over copper-molybdenum porphyry deposit located 34 km to the southeast, north of Powell River and the Gambier Copper deposit in Howe Sound.
QA/QC
Analytical work for samples was completed by ALS Canada Ltd. an ISO/IEC 17025 2017 Accredited Lab, with sample preparation and geochemical analyses in North Vancouver, BC. Core 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 PGM-ICP24 procedure which involves fire assay preparation using a 50-gram charge with an inductively coupled plasma-atomic emission spectroscopy finish ("ICP-AES"). Multi-element data for 48 elements was determined for all samples by the ME-MS61 procedure, which involves a four-acid digestion followed by ICP-AES and inductively coupled plasma- mass spectrometry.
Rigorous procedures are in place regarding sample selection, collection, chain of custody and data entry. Certified assay standards and blanks are routinely inserted into the sample stream of diamond drill samples to ensure integrity of the assay process. All diamond drill samples included in this news release have passed the QA/QC procedures as described above. Core was sampled using a manual splitter, with half of each interval sent to the lab for analysis, and the other half retained with sample intervals marked on the boxes.
