O3 Mining Drill Results Confirm VMS Deposit Environment at Horizon Project
November 13, 2023
The sizeable prospective belt within the Horizon Project and the multiple geophysical anomalies identified by O3 Mining have provided the fundamental elements to allow for the discovery of significant VMS deposits.
TORONTO, Nov. 13, 2023 /CNW/ – O3 Mining Inc. (TSXV: OIII) (OTCQX: OIIIF) ("O3 Mining" or the "Corporation") is pleased to announce that it has received the results of the two inaugural drill holes completed over the prospective Volcanogenic Massive Sulphide ("VMS") belt within the Horizon Project, in Val-d’Or, Québec, Canada ("Horizon" or the "Horizon Project").
- Hole O3HR-23-001 intercepted a laminated sulphide-rich siliceous tuff containing highly anomalous base and precious metal values of up to 0.24% Cu, 0.15% Zn, 0.1 g/t Au, and 1.4 g/t Ag over 1.4 metres from 356.0 metres.
- These anomalous values are well within the range of values encountered in VMS related exhalative horizons in other prolific belts of Abitibi like the C Contact at Noranda and the Key Tuffite at Matagami.
- The exhalative horizon in O3HR-23-001 is located along a 2.5 kilometres long chargeability induced polarization ("IP") and magnetic anomaly contained within a bimodal (mafic-felsic) volcanic sequence reaching 14 kilometres in length and interpreted to be equivalent to the Louvicourt Group, which hosts the Louvicourt VMS deposit in the Val-d’Or district (14Mt at 3.5% Cu, 1.5% Zn, 25.9 g/t Ag and 0.9 g/t Au).
- Eight other IP anomalies have been obtained within the 14 km long volcanic sequence, all of which remain to be tested.
O3 Mining’s President and Chief Executive Officer, Mr. José Vizquerra commented: "We are very excited about the initial results at the Horizon Project that confirm the discovery of a fertile environment supporting a highly prospective VMS deposit. VMS deposits represent some of the richest sources globally of a diverse group of strategic metals including copper, zinc, and lead. VMS deposits can also produce significant amounts of gold and silver as byproducts. The sizeable prospective belt within the Horizon Project and the multiple geophysical anomalies identified by O3 Mining have provided the fundamental elements that allow for the discovery of VMS deposits. These meaningful results create a new focus of interest on the project that warrants subsequent drilling."
Base and precious metal anomalous exhalites in VMS deposit environments have been widely documented. They represent a hiatus in volcanism where localized hydrothermal venting produced VMS deposits. They normally extend at the district scale and thus become a fundamental marker horizon that guides the explorationist in search of VMS deposits. Also, the presence of felsic volcanic rocks is another characteristic of the VMS belts, and such rocks have been mapped by government geologists at the Horizon VMS target.
Limited historical work has been done in that part of the Horizon Project. Nevertheless, the historical drill hole 5071-04, drilled by Breakwater Resources in 1996 (Perchat, 1996, GM54030), under the Cauldon showing returned 4.6% Zn and 29.1 g/t Ag over 5.8 metres in what is reported as silicified ultramafic rocks about 1.5 km southeast of O3HR-23-001. Field review of the Cauldron showing by O3 Mining geologists shows that the zinc mineralization is associated with a metamorphosed cherty and laminated horizon, interpreted as an exhalite horizon. Historical drilling along that trend cut zinc – silver mineralization over 600 metres strike length and remains open in all directions. O3 Mining completed a high-resolution drone mag survey in March 2022 over the entire Horizon Project with flight lines spaced at 50 metres for a total of 712 linear-kilometres. The discovery by prospecting in summer 2022 of a sulphide-rich laminated horizon (named GP-2) sparked the interest of O3 Mining’s geologists. The decimetric horizon contains 15% finely laminated pyrite and pyrrhotite, and a grab sample returned 0.7 % Cu, 0.5 g/t Au and 9.4 g/t Ag. Claims have been staked to cover the prospective belt to the northwest, up to Malartic Lake, to join O3 Mining’s Heva project. The latter has since been amalgamated into the Horizon Project. A VTEM® electromagnetic ("EM") survey (370 linear-km, 100 m spacing) was completed in December 2022, and IP surveys (pole-dipole and gradient) were completed during winter 2023. The IP surveys identified weak to moderate anomalies, one of which is 2.5 kilometre long and coincident with the GP-2 showing. Conceptually, the IP anomalies could represent volcanogenic horizons, which in return could lead to the discovery of VMS deposits below the VTEM penetration limit (approximately 250 m). During the summer 2023, O3 Mining’s staff completed stripping of the GP-2 showing, more mapping and prospecting as well as a systematic soil sampling survey (assays pending). The two inaugural drill holes completed last summer were targeting the IP anomaly coincident with the GP2 showing. In-hole Pulse EM surveys conducted in both holes, revealed an in-hole anomaly in O3HR-23-001. The two inaugural drill holes were spaced by 1.4 kilometres and cut the prospective horizons at some 300 metres vertical.
The next steps at the Horizon Project will consist of fence drilling to identify the prospective horizons in terms of VMS deposition or emplacement. Each prospective horizon will be characterized by its IP and soil response. The best targets will be drill tested at a 400-metre spacing at a vertical depth of 300 metres and pulse EM surveys will be completed in each hole to be able to rapidly cover the horizons and discover significant VMS mineralization.
The Horizon Project is located directly to the northwest of Marban Alliance. It consists of 192 claims covering 8,778 hectares, contiguous with Marban Alliance. The exploration stage at Horizon is less advanced than Marban Alliance, even though it covers the traces of the prolific Marbenite and Norbenite shears. The southwestern portion of the Horizon Project also covers the eastern end of the Blake River Group and a portion of the Temiskaming Group, where the auriferous Parfouru fault has been recognized. Also, the northern portion covers the Louvicourt Group described in the current press release.

Intercepts occur within geological confines of major zones but have not been correlated to individual vein domains at this time. Half-core samples are shipped to Agat laboratory in Val-d’Or, Québec, and Mississauga, Ontario for assaying. The core is crushed to 75% passing -2 mm (10 mesh), a 250 g split of this material is pulverized to 85% passing 75 microns (200 mesh) and 50 g is analyzed by Fire Assay ("FA") with an Atomic Absorption Spectrometry ("AAS") finish. Samples assaying >10.0 g/t Au are re-analyzed with a gravimetric finish using a 50 g charge.
Commercial certified standard material and blanks are systematically inserted by O3 Mining’s geologists into the sample chain after every 18 core samples as part of the quality assurance and quality control ("QA/QC") program. Third-party assays are submitted to other designated laboratories for 5% of mineralized samples. Drill program design, QA/QC, and interpretation of results are performed by qualified persons employing a QA/QC program consistent with NI 43-101 and industry best practices.
