1911 Gold Corporation (TSX-V: AUMB) (OTC: AUMBF) is pleased to report an updated underground Mineral Resource Estimate for the True North Gold Project, located within the Company’s 100% owned Rice Lake property in southeastern Manitoba, Canada.

Highlights

• Underground MRE defined for the True North Gold Project is reported within mineral resource constraining envelopes using a 2.25 grams per tonne Gold threshold. All blocks within the envelopes are reported and tabulate as:
  • Indicated Mineral Resource of 3,516,000 t @ 4.41 g/t Au containing 499,000 ounces Au 
  • Inferred Mineral Resource of 5,490,000 t @ 3.65 g/t Au containing 644,000 oz Au
• The MRE highlights areas with exploration targets for resource expansion both down plunge and along strike to the modeled veins and within areas with historic drillholes that require drilling prior to including them in future resource estimates 
• 1911 Gold has started a surface drill program with target areas that include:
  • Gold mineralization intersected in historic drillholes that are in new target areas along strike from the resource and within 400 m of surface
  • New targets identified during the vein modelling that are proximal to Au-bearing shear zones within favourable host rocks
• Management will hold a webinar on Tuesday, November 26, 2024, at 10:00am (EST) to present and review the results of this mineral resource estimate (details below)

Shaun Heinrichs, President and CEO of 1911 Gold, commented, “Validating the project database and remodeling the vein wireframes to support a Mineral Resource Estimate was a critical first step along the path to restarting production at the True North Gold mine. The resulting resource model now better reflects the shape of the veins, and the consolidated model will be important as we work closely with Eric Vinet on building a long term, sustainable development plan. We are particularly pleased with the areas that have been identified as having potential to expand the mineral resources with further drilling, in addition to the new targets generated. We continue to leverage off the work done by our predecessors as well as our enhanced knowledge gained from the re-interpretation work completed, which has identified numerous high priority resource expansion areas and new geological targets from our refined geological model.”

1911 Gold Executive Chaiman, Gary O’Connor, commented “We are pleased to have our updated Mineral Resource Estimate at the True North Gold project to produce a robust and solid high grade underground gold resource which will form the basis of our plans to generate a redevelopment plan with significant valuation for the past producing fully constructed and permitted gold mine. Significant potential to grow the new resource, as well as to discover and define new resource targets outside of the mineral resource areas, has been a major bonus from the reinterpretation and new resource modelling. We look forward to releasing the results of the current drill program and presenting the upside potential to grow and develop the project.”

Mineral Resource Estimate 

The underground MRE resource is based on a drill hole database that was rebuilt by 1911 personnel (completed on July 31, 2024) containing a total of 11,632 drill holes, with a total core length of 1,520,700 m. Of these drillholes, 3,157 drill holes intersected the modelled vein solids and 30,525 samples, covering 15,838 m, were included in the resource estimation (Table 1).

The updated resource is comprised of 66 modelled vein shapes. The geological interpretation of each vein incorporated the host lithologies, mineralization character, alteration style and structural features. The modelling was completed on cross-sections and level plans using drill hole data and detailed geology level maps drawn when the mine was in production. The level maps were also used to validate the vein traces and drill hole collar locations. The majority of the vein solids strike NW-SE or NE-SW (Figure 1) and plunge approximately 50 degrees to the NE or NW respectively. The mineralized gold trends tend to occur within shear zones and are hosted within favourable competent host rocks (gabbro, basalts and fragmental volcaniclastics). Three-dimension modelling of the vein solids was generated in “Leapfrog Geo”, a modelling software.

The underground MRE was completed on November 13, 2024, and is reported within mineral resource constraining envelopes using a 2.25 g/t Au threshold. All blocks within the envelopes are included in the MRE results presented in Table 1.

Notes:

1. The effective date of the MRE is August 29, 2024, which is the date when all scientific and technical data was submitted to Lions Gate Geological Consulting (“LGGC”).
2. The MRE follows the November 29, 2019, CIM Estimation of Mineral Resources and Mineral Reserves Best Practice Guidelines.
3. Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability. There is no certainty that all or any part of the Mineral Resources estimated will be converted into Mineral Reserves. The estimate of Mineral Resources may be materially affected by environmental, permitting, legal, title, taxation, socio-political, marketing, or other relevant issues.
4. The CIM definitions were followed for the classification of Indicated and Inferred Mineral Resources. Indicated Mineral Resources were assigned for blocks with three drill holes within 30 m (100 feet “ft”) and inferred blocks were assigned for blocks with one drill hole within 46 m (150 ft).
5. Ounces and tonnes have been rounded to the nearest 1,000 therefore sums in the table may not add-up due to rounding.
6. Resource constraining envelopes were built around contiguous clusters of blocks at a nominal cut-off grade of 2.25 g/t Au. The mineral resources are reported at a 0.00 g/t Au cut-off within the envelopes. The gold grade threshold for the resource envelopes of 2.25 g/t Au is based on assumptions of a gold price of US$2,000/oz, an exchange rate of US$/C$ 0.75, mining operating costs of C$132/t, processing costs of C$34/t, G&A of C$12/t and average gold recoverability of 94%. The vein solids were built with a minimum width of 1.2 m. This same width was used for the mineral resource envelopes. 
7. A bulk density of 2.76 t/m³ (0.086 short tons/ft³) was used to convert volumes to tonnes for all blocks in the mineral resource estimation.
8. The assay gold values were capped to 342.5 g/t Au (10 oz/short ton) and a restricted outlier strategy was applied to each vein to restrict local extreme grades to 15 m (50 ft) from the composite.
9. Gold grades were estimated into a 4.6 m (15 ft) block model using inverse distance squared (ID²) method and 0.46 m (1.5 ft) composited data restricted within the vein solids.

The MRE was completed using HxGN MinePlan^TM 3D software and includes the estimation of gold grades into a 4.6 m block model (15x15x15 ft) using Inverse Distance Squared (ID²) method. Composites from a minimum of two drill holes was required for a block to be interpolated with a gold grade.

Prior to estimating block grades, potentially anomalous outlier grades were identified and their influences on the grade model was controlled during interpolation through the use of traditional top‐cutting and outlier restrictions. The assay gold values were capped to 342.5 g/t Au (10 oz/short ton). The composites for each of the estimated veins were reviewed by histogram/probability plot and a restricted outlier strategy was employed to limit the influence of extreme gold grades to 15 m (50 ft) from a composite location.

The resource constraining envelopes were built around contiguous clusters of blocks at a nominal cut-off grade of 2.25 g/t Au. The mineral resources reported in Table 1 are reported at a 0.00 g/t Au cut-off within the resource constraining envelopes as required by CIM guidelines for declaring an underground mineral resource estimate. The sensitivity of the block values within the 2.25 g/t Au resource constraining envelopes to gold grade is included Table 2. The block tabulations included in Table 2 do not constitute mineral resource estimates and are included to illustrate block grade sensitivity only within the 2.25 g/t Au envelopes.

Indicated Mineral Resources were assigned if a block was within 30 m (100 ft) of three drill holes and Inferred Mineral resources if a block was within 46 m (150 ft) of one drill hole.

Mineral Resource Potential Discussion

The MRE has identified areas in the deposit where increased drill hole spacing could result in more blocks being interpolated with gold grades and increased levels of classification for some blocks. These areas lie close to the historic stopes in the mined areas of the project where blocks were not estimated due to uncertainty of the locations of the stope solids. 1911 Gold will undertake a thorough review and validation of the mined shapes in order to better define the potential for resources proximal to historic stopes.

The potential for adding mineral resources proximal to areas of known mineralization and at new emerging targets will be reviewed through updated vein and structural interpretations and refinement of the geological understanding of the True North Gold Project.

The Company is planning a review of the underground facilities at True North Project to define the most suitable areas for underground drilling to support a drilling campaign to potentially upgrade and expand the current resources inventory down plunge and along strike of the resource.

Future Plans

1911 Gold is currently completing first phase surface drilling within areas outside of the resource in near surface and near infrastructure areas where historical drill intercepts have already intersected significant mineralized veins, and the new geological model has identified significant new resource potential. Initially three prioritized target areas have been identified and are the target of the current drill program (see Company’s press release: “1911 Gold Initiates Surface Drill Program on New Exploration Targets at the True North Gold Mine”, dated October 3, 2024).

With the completion of the MRE the 1911 Gold geology team will define and prioritize resource expansion areas for further drilling to include in future resource updates. The prioritization of deep new targets is also underway and the drill targeting of these will also be prioritized. The Company has commenced work on a preliminary development and mine plan, working closely with Éric Vinet, recently engaged as a key technical advisor, focusing on identifying suitable mining methods, expected costs, and overall economics supporting the restart strategy.

Quality Assurance/Quality Controls (QA/QC) Procedures

All drill data that supports the mineral resource estimation were completed by previous operators and were drilled between 1994 and 2017. The majority of the drill holes were BQ sized core (1,895 DDHs) with a lesser number being AQ sized core (1,112 DDHs), NQ sized core (137 DDHs) and HQ sized core (11).

Both 1911 Gold and LGGC have reviewed the historical QAQC data that supports drilling and assay data and finds them acceptable to support the MRE.
