Solstice Gold closes Leckie Gold Zone acquisition, 57 km² in Abitibi

Solstice Gold Corp. (TSXV: SGC) (“

Solstice

” or the “

Company

”) is pleased to announce, further to its August 24, 2026 news release, it has closed the acquisition of two patented claims totaling 24 hectares, which host the Leckie Gold Zone (“

LGZ

”). The LGZ includes a 160 m-deep shaft, underground development on five levels and more than 23,000 m of historical drilling that has confirmed significant historic gold and silver mineralization. The agreement also includes a strategically located group of 43 unpatented mining claims totaling 9.4 km

, adjacent to the Company’s Red Cedar Discovery and approximately 260 m from the LGZ patents. This acquisition consolidates a substantial portion of this largely unexplored part of the Abitibi Subprovince in Ontario, known for its gold potential (

Figure 1

). It also significantly expands Solstice’s core land position, adds the LGZ as a focus for expansion drilling and enhances the Company’s ability to explore the Strathy Gold Project at a larger district scale. Unlike much of the Abitibi, the Temagami Greenstone Belt is under-explored and has not been the subject of modern regional-scale exploration techniques.

Consolidated Strathy Gold Project after addition of the Leckie Gold Zone and Southern Unpatented Claims. Note both claim groups’ proximity to the new greenfields Red Cedar Discovery.

Pablo McDonald, CEO, stated, “

Closing the Leckie Gold Zone acquisition cements the Strathy Gold Project as the newest exciting exploration play in the Abitibi. We now have district-scale control of gold potential in the Temagami Greenstone Belt, including an area of historical drilling that hosts significant historical gold intercepts that are open for follow up. Strathy now combines near-term brownfields exploration upside at the Leckie Gold Zone with significant greenfields discovery potential across a district-scale land package. Our focus now turns to commencing groundwork immediately in preparation for drilling the Leckie Gold Zone and surrounding discoveries to demonstrate a possibly much larger gold system and potential resource. We believe this next phase of exploration has the potential to be an important catalyst for value creation for Solstice Gold shareholders

.”

Key Highlights of the Acquisition and Consolidated Project:

Strong Historical Gold Intercepts

LGZ drilling includes

4.85 g/t Au over 17.10 m, 7.24 g/t Au over 10.45 m, 9.10 g/t Au over 5.24 m and 4.35 g/t Au over 10.30 m

1

. Of 133 historical drillholes with assays, 62% returned intercepts of ≥3.0 g/t Au over at least 1.5 m, demonstrating a strong historical hit rate and significant follow-up potential.

Open for Expansion

Historical drilling was relatively shallow: 90% of qualifying intercepts occur above 250 m vertical depth and 67% above 150 m. The LGZ remains open along strike and at depth, within a broader mineralized system that includes Solstice’s recent discoveries. See

Figure 2

.

District-Scale Abitibi Gold Project

The acquisition consolidates the LGZ within Solstice’s 57 km

Strathy Gold Project, creating a district-scale exploration position centred on an established gold zone targeted for expansion drilling.

Modern Exploration Unlocking New Targets

Solstice IP surveys show a strong association between the LGZ and elevated chargeability and identify untested anomalies along strike and at depth. Oriented-core work has also identified multiple vein sets, providing new structural vectors for future drilling. See

.

Solstice Resampling Confirms Gold and Silver Grades

Due-diligence resampling of historical LGZ core and surface samples returned results consistent with historical assays.

New Claims Add High-Priority Targets

The acquisition adds 43 claims within 100 m of both the LGZ and Red Cedar Discovery, covering undrilled extensions, the intersection of the Leckie Fault and an OGS-interpreted regional fault, and approximately 10 km of the Link Lake Deformation Zone.

Next Steps: Preparation for Phase 1 LGZ Drilling

Surface work on the LGZ including detailed mapping and relogging and sampling of historical core will commence immediately after Solstice gains access to the claims. This surface work will add important data and context to our drill targeting, and will lead to a detailed drill program to be executed starting in Q4, 2026.

Purchase Agreement

Pursuant to a definitive purchase agreement, dated August 22, 2026, among the Company, Koala Canada Exploration Inc., Lithium of Nevada Pty Ltd. and Resilience Minerals Limited, the Company paid $600,000, issued 2,000,000 common shares (the “

Common Shares

”), and transferred 11 unpatented claims of the Company to arm’s length parties as consideration for the patented and unpatented claims as well as supporting technical data (the “

Transaction

”). The Common Shares are subject to a hold period of twelve months from closing pursuant to the terms of the purchase agreement and are also subject to a statutory hold period of four months and one day in accordance with applicable Canadian securities laws. No finder’s fees were paid with respect to the Transaction. The Transaction remains subject to final approval of the TSX Venture Exchange.

Historical Sampling and Drilling Data and Information

The sampling, drilling data and other historical scientific and technical information presented in this news release (the “

Historical Exploration Information

”) is historical in nature. It was prepared and published before Solstice acquired an interest in the property. The reader is cautioned that the Historical Exploration Information is based on prior data and reports previously prepared by third parties without the involvement of Solstice. Solstice has undertaken some limited independent analysis of the Historical Exploration Information in order to attempt to verify the results (see “Solstice Resampling Confirms Gold and Silver Grades” above). The limited analyses to date conducted by Solstice confirmed that a sample of certain check assays of the historical assay results are consistent with the published historic assay results. However, the reader is cautioned not to treat the Historical Exploration Information as current. No qualified person has completed sufficient work to verify the Historical Exploration Information; accordingly, the information may not be reliable. Other than Solstice’s limited testing, no independent quality assurance/quality control protocols are known for the historic samples and drill holes and therefore the Historical Exploration Information may be unreliable. Solstice considers the Historical Exploration Information relevant as the Company will use this information as a guide to help plan future exploration and drilling programs. Solstice considers the Historical Exploration Information to be reliable only for this limited purpose. The Company's future exploration work will include efforts toward further verification of the Historical Exploration Information through drilling and assay results.

About Solstice Gold Corp.

Solstice is an exploration company with quality, district-scale gold projects in established mining regions of Canada. Our 57 km

2

Strathy Gold Project hosts high-grade gold mineralization, including visible gold, over a wide area straddling two NE-SW-trending structures. It is located in the Abitibi Subprovince of Ontario and has never been systematically explored in its history. Alpha IP surveys totaling over 34 line km completed in 2024 and 2025 defined 50 new targets and show that the largest IP anomaly corresponds with the Red Cedar Discovery of 8.5 g/t Au over 3.5 m. Follow-up drilling at Red Cedar intersected multiple high-grade intercepts with visible gold, as well as a “Leckie-type” intercept approximately 600 m from the Leckie Gold Zone, which has been the focus of more than 23,000 m of historical drilling. The acquisition of the Leckie Gold Zone consolidates the Strathy Gold Project and unlocks, for the first time, the potential to expand the historically significant Leckie Gold Zone and unlock the substantial potential for future discoveries and resource expansion at Strathy.

Our Qaiqtuq Gold Project which covers 662 km
