G Mining Ventures Confirms High-Grade Core and Extends Mineralization Beyond Main Pit at Tocantinzinho Gold Project
Highlights of intercepts include: 193.6m of 1.48 g/t Au including 12.8m of 4.59 g/t AuBROSSARD, October 18, 2022 - G Mining Ventures Corp. ("GMIN" or the "Corporation") (TSXV:GMIN)(OTCQX:GMINF) is pleased to announce results from its recently concluded delineation core drilling program at its 100%-owned Tocantinzinho Gold Project ("TZ" or the "Project"), located in the State of Pará, Brazil. The campaign has successfully confirmed the continuity of higher-grade gold in the main pit area, confirmed that the mineralization extends below the existing pit shell, and increased the definition of areas to be mined during pre-production. Highlights of recent results are outlined below, where all intercepts are presented as calculated true width, unless stated otherwise:
- Confirmation of continuity of mineralization and presence of a high-grade core:
- 193.6m of 1.48 g/t Au (TOC285)
- Including high-grade intercepts of 12.8m of 4.59 g/t Au and 5.0m of 10.61 g/t Au
- 144.7m of 1.70 g/t Au (TOC286)
- Including high-grade intercepts of 13.7m of 2.41 g/t Au and 41.0m of 3.62 g/t Au
- 126.5m of 1.55 g/t Au (TOC290)
- Including high-grade intercepts of 5.1m of 4.52 g/t Au and 9.4m of 4.65 g/t Au
- 175.9m of 1.03 g/t Au (TOC289)
- Including high-grade intercepts of 24.5m of 3.22 g/t Au and 5.6m of 5.05 g/t Au
- 193.6m of 1.48 g/t Au (TOC285)
- Confirmation of mineralization outside of the feasibility study pit shell:
- 72.1m of 1.05 g/t Au (TOC284A) including 14.8m of 3.45 g/t Au
- 10.4m of 0.98 g/t Au (TOC288) including 4.8m of 1.67 g/t Au
All intercepts are presented as calculated true width unless stated otherwise
Louis-Pierre Gignac, President & Chief Executive Officer, commented: "Our latest drilling at TZ confirms the presence of high-grade zones within the main deposit, with mineralization now extending below the current pit design. Results confirm that mineralization is continuous along width close to 200 meters and to a depth of 400 meters. While we are primarily focused on mine construction, upcoming exploration drilling will be conducted on the near-mine Castor target, where successful sampling and reconnaissance drilling has returned strong results."
Deposit Expansion Program: Further Details
The Tocantinzinho deposit consists of a vein stockwork system within a variably altered granite, named Smoky and Salami granite in reference to their colors. The deposit is sub-vertical, southeast trending with excellent grade continuity over approximately 900m in strike-length, 150 to 200m widths and vertical extents up to 400m.
A total of 6,234m has been drilled this year at the deposit, with the principal objective to delineate the first years of production while testing the near surface limit of the tailings, saprolite and unit contacts (Figure 1). Out of the 28 drillholes, 9 have assays pending, 13 presented here have significant intercepts and the last 6 aimed to define ore/waste boundaries and lithological contacts. The 2022 drill program has been successful in confirming the grade continuity of the deposit with several large intercepts of continuous mineralization up to 193.6m of 1.48 g/t Au (TOC285) and 144.7m of 1.70 g/t Au (TOC286) (Figure 2). All intercepts are presented in calculated true width.
Within these mineralized intervals, the drilling also confirmed the presence of a high-grade core with intervals such as 41.0m of 3.62 g/t Au (TOC286), 24.5m of 3.22 g/t Au (TOC289) and 12.8m of 4.59 g/t Au (TOC285). This higher-grade body present continuous mineralization above 1.5 g/t Au and follows the SW lineament plunge of the Tocantinzinho sinistral shear zone. The pending assays test the continuity at depth of the grade along this trend (TOC306).
The 2022 drilling campaign also tested the mineralization at depth outside of the reserve pit shell in the northern and southern portion. The extension at depth of the SW plunge returned 10.4m of 0.98 g/t Au (TOC288) including 4.8m of 1.67 g/t Au. Significant intercepts along the northern portion of the pit wall includes 72.1m of 1.05 g/t Au (TOC284A) including 14.8m of 3.45 g/t Au.

New Targets and Upcoming Exploration Program
Castor Target
Located directly southeast of the Tocantinzinho deposit, Castor is a target identified along the TZ trend (Figure 3). Castor is a high priority target identified through sampling and successful reconnaissance drilling.
Highlights include:
- High-grade surface samples
- Grab samples have assayed up to 25.40 g/t Au and, while the rocks are not in-situ, their source is most likely proximal.
- Successful first pass drilling
- Initial drill holes toward the southeast have returned attractive results including 8.0m of 1.66 g/t Au (TOC214) and 8.4m of 2.20 g/t Au (TOC212).
- The prolific TZ trend (Figure 5) has seen limited drilling.
- Ongoing sampling continues to identify further anomalous results.
- Existing soil sampling presents anomalous values in gold in this zone.
- The lines are currently on an 800m spacing.
- Infill soil sampling lines are in progress to tighten to a 400 m spacing.
- Current Activity and Next Steps
- Follow-up drilling on the initial hits is currently underway, as is a thorough mapping and sampling campaign to refine and prioritize drill targets.
- Further drill testing, based on the results of current activity and additional geophysical data, is planned for Q4, 2022 and into 2023.

Déjà Vu Target
Simultaneously to the near deposit exploration effort, a regional soil sampling program will be initiated to complete gaps in the existing information on GMIN claims (Figure 4). The program will start along the Déjà Vu target, on the western portion of the property. This target is defined based on the soil sampling anomaly observed along a structural trend parallel to TZ. Grab samples returned assays up to 100 g/t Au. So far, no drilling has tested this trend. Along with the completion of the soil sampling campaign, mapping and grab sampling will contribute to defining future drilling targets.

Tocantinzinho Trend - A large prolific corridor
Tocantinzinho is the largest known gold deposit in the Tapajós Gold Province. The region hosts other gold deposits (Figure 5), such as Cuiù Cuiù (Cabral Gold Inc.), Palito and São Chico (Serabi Gold plc), and São Jorge (GoldMining Inc.), all located along the Tocantinzinho trend, a major regional NW-SE shear zone. Tapajós is a vast underexplored gold province with an estimated between 15 and 30 M oz of gold produced in alluvium/saprolites in the region, however no quantitative study exists. Base metals are also present in this fertile province as shown by the presence of Anglo American plc and Nexa Resources S.A. in the area.
The large 996 km2 land package held by GMIN (through its Brazilian subsidiary) is within the prolific Tocantinzinho trend. Limited work has been completed around the Tocantinzinho deposit which is less than 5% drill tested. Agência Nacional de Mineração (ANM), the Brazilian federal mining agency, has granted the renewal of all 24 exploration claims on the property package, and with only two claims still under review.
