1911 Gold Delivers Positive PEA for True North Highlighting Robust

Economics with Low Capital Intensity and High Returns

Vancouver, February 10, 2026 – 1911 Gold Corporation ("1911 Gold" or the "Company") (TSXV: AUMB;

OTCQX: AUMBF; FRA: 2KY) is pleased to announce significant positive results from the independent

Preliminary Economic Assessment (“ PEA”) for the True North Gold Project (“ True North ”), located in

southeastern Manitoba, Canada. The PEA was prepared by AMC Mining Consultants (Canada) Ltd.

(“AMC”), in accordance with National Instrument 43 -101 Standards of Disclosure for Mineral Project (“NI

43-101”), with all financial figures expressed in Canadian Dollars unless otherwise stated.

The PEA outlines a robust gold mining operation utilizing the fully built and permitted infrastructure ,

including shafts, underground workings, and the processing and tailings management facility . 1911 Gold

has estimated the infrastructure replacement value as being in excess of $400 million. The plan targets

steady-state production of 58,114 ounces per annum with a mine life of 11 years. Management will host a

webinar on Tuesday, February 10, 2026 at 10am PT (1pm ET), to discuss the PEA results and to answer

any questions with respect to the PEA and the planned production restart strategy. Please refer to the

details at the end of this release.

PEA Highlights:

• Robust Economics (After-tax): Net present value (5%) (“NPV”) of $391 million, internal rate of

return (“IRR”) of 105%, and a payback period of 2.2 years at a long-term gold price of US$ 3,000

per ounce (“oz”); at a constant gold price of US$4,800/oz, the NPV is $998 million, no calculated

IRR due to no years with a negative cash flow , and an almost immediate payback period of 1.0

year.

• Production Profile: Steady-state production profile of 1,215 tonnes per day (“ tpd”) for a verage

payable gold production of 58,100 oz per annum (“oz/year”) (Years 3-8) with an 11-year life of mine

(“LOM”).

• LOM Cash Flow: Total payable gold production of 527,100 oz LOM with the current mineral

resources, generating $545 million undiscounted after-tax free cash flow1 and generating 326 full-

time jobs.

• Fully Permitted, Low Capital Project: Initial capital expenditures (“Capex”) of $ 59.2 million,

utilizing the currently built and permitted payable infrastructure. Additional Capex of $46.7 million

during the first 2 years of ramp -up, and $367.2 million of sustaining capital over LOM with a high

profitability index of 6.6 and low peak investment of $59.2 million in Year 1.

• Processing: Average diluted mill head grade of 4. 32 grams per tonne gold (“g/t”, “Au”) with gold

recoveries of 93.5% over the LOM.

• Cash Costs and AISC 1: Producing gold at a cash cost of US$1,390/oz and all in sustaining cost

(“AISC”) of US$1,897/oz.

• Near-Term Production: Production due to start in the first half of 2027 (“H1 2027”) with test mining

planned for the second half of 2026 (“H2 2026”).

• Production Growth: 1911 Gold has identified exc ellent potential to increase production by

developing recently discovered zones such as San Antonio Southeast (“SAM SE”), San Antonio

West (“SAM W”), and Shore which are adjacent to existing infrastructure and not included in the

study, in addition to regional targets.

1. AISC and Free Cash Flow are non -IFRS financial measures and have no standardized meaning under IFRS Accounting

Standards (“IFRS”), and may not be comparable to similar measures used by other issuers.

"The delivery of this PEA marks another defining moment for 1911 Gold, outlining a highly efficient, low -

capital path to the first phase of production with robust economics and exceptional returns,” stated Shaun

Heinrichs, President and Chief Executive Officer of 1911 Gold. “This plan leverages existing

infrastructure and a mining strategy suited to the ore body, significantly reducing the project’s capital

intensity and technical hurdles that challenged previous operators. Our staged development approach

provides a disciplined roadmap to ramp up operations toward an initial steady-state production. This PEA

proves that True North is not just a restart story, but is the cornerstone of a district-scale gold project in one

of Canada’s premier mining jurisdictions.”

Eric Vinet, Chief Operating Officer of 1911 Gold, stated “This PEA outlines a foundational plan to restart

operations at True North by optimizing existing infrastructure and confirms the economic viability of a safe

and efficient multi-mine operation. Beyond the scope of this study, we see significant potential to further

optimize these economics by establishing a centralized 'super -level' on Level 16. By connecting the

adjacent zones at Hinge, 007, and, potentially, Cohiba directly to the True North Main S haft, we can

transition to a gravity-fed, horizontal haulage model. The proximity of these zones - notably Hinge, located

within 100 m of existing infrastructure - supports the technical rationale for centralized hoisting, which has

the potential to materially reduce operating costs.”

The PEA is preliminary in nature, includes inferred Mineral Resources that are considered too speculative

geologically to have economic considerations applied to them that would enable them to be categorized as

Mineral Reserves, and there is no certainty that the PEA will be realized. Mineral Resources that are not

Mineral Reserves do not have demonstrated economic viability.

Sensitivities

1911 Gold has conducted a sensitivity analysis using the PEA financial model on the base case pre -tax

and after-tax NPV and IRR of the Project, using the following variables: metal price, initial capex, total

operating costs, and foreign exchange. Table 2 shows the a fter-tax sensitivity analysis results at various

long term gold price assumptions.

As shown in Table 3 and Table 4, the sensitivity analysis revealed that the project is most sensitive to

changes in gold prices, and foreign exchange and less sensitive to capital and operating costs.

Mining

The True North Gold Project will consist of underground mining extraction via four access points: the Main

“A” Shaft, the Hinge decline, the Cohiba decline and later the SG-1 decline. Initial mining and development

will be through the Main “A” shaft, providing access to Level 16 (-695 metres) and Level 26 (-1,145 metres),

and the Hinge decline , maximizing current underground development to accelerate development and

minimize initial capital costs . The initial plan for the development is to ramp up to a steady-state daily

production rate of 1,215 tpd (from years 3-8).

The mineral deposits and zones used in the mine plan are contained in a number of deposit areas over a

lateral distance of over 4,500 metres (‘m”) and down to depths of over 1,450 m below surface through a

series o f winzes and internal declines . The deposits are all amenable to underground mining using

longitudinal long-hole open stope mining methods, with minimum dimensions of 25 m long by 1.5 m wide

by 18 m high between sublevels, assuming 15% dilution with no gold grade and 97% mining recovery. The

mining cycle will incorporate a strategic backfill plan, utilizing development waste rock to fill depleted stopes.

This will enhance ground stability and significantly reduce operating costs by minimizing the volume of

waste material required to be hoisted to surface, thereby optimizing available shaft capacity for high-grade

ore.

A total of 4,066,000 tonnes at an average diluted g rade of 4.32 g/t Au will be extracted under the current

proposed plan for a total of 527,100 oz of payable gold produced.

Notes

*Tonnage and grade estimates derived from the Mineral Resource estimate prepared by Lions Gate Geological Consulting (Q.P

Susan Lomas, P.Geo), effective date 29 August 2024 (see below). AMC applied a cut-off grade of 2.7 g/t Au to the resource model

and then allowed for dilution and mining losses. Gold price used in the cut-off calculation was US$2,500 per ounce, exchange rate

of 0.72 CA dollars to one US dollar.

Within the “A” shaft, mineralized material will be loaded on the Level 26 loading pocket and skipped to the

mill at surface and, for the decline, accessed deposits will be hauled via trucks to the True North processing

facility. Processed tailings will be pumped to the central operating and permitted tailings management

facility. Development waste is currently planned to be stored on surface and used for ongoing infrastructure

projects, including possible tailings dam wall lifts in the future.

Processing

The fully permitted processing facility operated for a number of years and is reported to have produced

1.93 million oz of gold historically from 9.60 million tonnes at a grade of 6.65 g/t Au . The process plant

consists of a crushing and grinding circuit, with a portion of the circulating load passed through gravity

concentrators. The concentrate from th e gravity concentration i s upgraded on a shaking table and the

resulting concentrate direct smelted. The tails from the concentrat ion are returned to the head of the

grinding mill and the fines from the grinding circuit are fed into a flotation circuit to produce a flotation

concentrate which is reground and leached with the remaining process feed using a six -stage carbon-in-

pulp (“CIP”) circuit. Dissolved gold is then eluted and gold doré is smelted and poured at site with an electric

induction furnace.

An upgrade of the crushing circuit is required to restart commercial production, otherwise the remainder of

the processing plant is intact and recently operated. Historically, the process plant has recorded average

recoveries of 94.0% of contained gold and has operated up to 2,250 tpd.

Tailings Management

The Tailings Management Facility (“ TMF”) is located 1.6 km north of the process ing facility in an area

naturally defined by bedrock ridges around the perimeter of a flat area. Tailings have been pumped from

the processing facility to the TMF via pipeline. During mine operations the tailings are transported as slurry,

with 34% solids by weight. An expansion of the facility was completed in 2015 with the construction of the

East Tailings Management area, located immediately east of the TMF, including the polishing pond, where

water is pumped in and discharged as required. Enough storage exists within the TMF for approximately

775,000 tonnes or over 2 years production under the PEA mine plan and permits are in place to expand

the capacity of the TMF as needed.

Initial and Sustaining Capital Costs

The total initial (pre-production) capital cost is estimated to be $59.2 million with an additional $46.7 million

of capital during the first 2 years ramp -up period, prior to commercial production . Sustaining capital costs

are estimated to be $367.2 million over the LOM (excluding $5.0 million of closure costs and salvage value).

The initial and sustaining capital costs were compiled using the following sources:

• Mining capital costs were developed by AMC, based on the mine plan

• Processing, infrastructure, project development and project in-directs were developed by AMC, and

are inclusive of the underground development required to restart production, upgrade of the

crushing circuit for the processing plant, camp expansion and other required infrastructure

• Sustaining capital costs consist of mining costs including underground resource infill and

delineation costs, development costs, tailings storage facility expansions, and water management

structures

LOM Cash Flow

The project is expected to generate $545 million undiscounted after -tax free cash flow (Base Case), and

$1,314 million undiscounted after-tax free cash flow (at a gold price of US$4,800). Once operational, the

mine is expected to support approximately 3 26 full-time positions, contributing to local employment and

regional economic development.

1911 Gold Opportunities

The PEA results offer consideration of several initiatives that may enhance the Project, including:

Processing Capacity & Efficiencies:

• Existing Processing Capacity - Additional capacity currently exists within the processing

plant to increase throughput to the mill with additional mine production.

• Expand Current Processing Facility - Ability to expand the capacity beyond the current

processing capabilities of the plant, by upgrading the secondary crushing circuit and increasing

CIP retention time with additional tank capacity

Additional Resource Opportunities:

• Immediate Resource Expansion – Significant potential exists as extensions of the mineral

resources used for the PEA mine plan due to the lack of sufficient drilling density.

• Additional Resource Potential (Mine Footprint) – Recent exploration discoveries within the

True North mine footprint occur adjacent to mine infrastructure, with high potential to add

resources, including SAM W, SAM SE, and Shore.

• Potential Addition of New Resources from Regional Targets – Additional resources and

resource potential exists within the Rice Lake Greenstone Belt, over a 9 0-km strike length

within 1911 Gold’s 100% owned ~62,000 hectares of ground. The Rice Lake Properties include

the Ogama-Rockland gold deposit, all of which have road access, are within trucking distance

to the mill, and are proximal to hydro-electric power.

Waste Reduction and Operational Efficiencies:

• Integrated Underground Waste Management – Potential to utilize development waste for

rock filling depleted stopes, significantly reducing the volume of waste hoisted to the surface.

This strategy is expected to lower operating costs and maximize available shaft capacity for

high-grade mill feed.
