Adina Lithium Project

Adina Lithium, a flagship Project

The Adina Lithium Project, Winsome team’s flagship project, was discovered in 2014 by the MRNF (government) geologist Adina Bogatu during regional mapping work. In 2018, a 1,726-metre drilling campaign was carried out on the main showing confirming the presence of a small-scale mineralized system.

In fall 2022, an exploration team working on behalf of Winsome made the discovery of the JAMAR showing, located 1.2 km directly east of the original showing. The showing was named to honor the team composed of Jason, Anaïs, Monserrat and Arnaud. They were looking for a place to land the helicopter, and the only accessible area covered the discovery outcrop. Initial drilling confirmed the significance of the discovery, with a 107.6 metre section grading 1.34% Li2O, drilled along the main trend of the zone (press release).

The 150 or so diamond drill holes completed since then have highlighted a vast zone extending over just over 3 km and hosting high-potential lithiniferous grades. In addition, this mineralized zone has been intersected by peripheral drilling to both the east and west, suggesting that the mineralized system extends beyond the current core.

In spring 2024, other promising discoveries were made, including the discovery of a new area 200 metre southwest of Adina. The results then confirm the presence of high-grade mineralization with a section of 61.5 metre at 1.62% Li2O, including 24.0 metre at 2.82% Li2O (press release).

 

On September 17th, 2024, Winsome Resources announced positive NI 43-101 compliant Preliminary Economic Assessment (“PEA”) results including a Mineral Resource Estimate (“MRE”) for Adina (press release). The PEA is based on the Adina Lithium Project and on the proposed acquisition of the Renard diamond mine (“Renard”) (together, “the Project”). On October 1st, 2024, Winsome Resources has filed the technical preliminary economic assessment (“PEA”) study report on its Adina Lithium Project. This study is available on SEDAR+.

The Project considers the development of Adina through repurposing the processing facility at Renard. The average processing throughput would be of 4,650 tonnes per day for a dense media separation only operation at an average lithium recovery of 67.2% at an average process plant feed grade of 1.24% Li2O through the life of mine. The Project would produce more than 5,000 kt of lithium concentrate at 5.5% Li2O.

After-Tax IRR and NPV8 has been evaluated at 42.9% and C$1.0 Billion, respectively. The Project is expected to generate over C$10.0 Billion of gross revenue and C$1.6 Billion in carbon, provincial and federal taxes and Québec mining duties as well as creating over 500 and 600 direct jobs during construction and operations, respectively.

Cautionary Statement – The reader is advised that the PEA summarized in this news release is intended to provide only an initial, high-level review of the Project potential and design options. The PEA mine plan and economic model include numerous assumptions and the use of inferred mineral resources. Inferred mineral resources are considered to be too speculative to be used in an economic analysis except as allowed for by NI 43-101 in PEA studies. There is no guarantee that inferred mineral resources can be converted to indicated or measured mineral resources, and as such, there is no guarantee the Project economics described herein will be achieved. Winsome has an exclusive option to purchase the Renard Operation as detailed in the Press Release of August 1st, 2024. The PEA contemplates usage of the infrastructure at Renard which will only be possible once the option is exercised, and all payments are made as contemplated in the terms of the Option Agreement. Winsome may be eligible for Clean Technology Manufacturing Investment Tax Credit. This legislation has been enacted on June 20, 2024. There is no guarantee the Company will be able to access the CTM-ITC. Investors outside Canada are cautioned that information contained in this announcement may not be comparable to information published by companies subject to the reporting and disclosure requirements of Australian securities laws. In particular, the MRE for Adina used in the PEA was prepared in accordance with the requirements of 43-101 – Standards of Disclosure for Mineral Projects (NI 43-101) and the Canadian Institute of Mining, Metallurgy and Petroleum (CIM) – CIM Definition Standards on Mineral Resources and Mineral Reserves adopted by the CIM Council, as amended (CIM Definition Standards) which differ from the JORC Code on the basis of assumptions.

CAUTION REGARDING FORWARD-LOOKING INFORMATION

This document contains forward-looking statements concerning Winsome. Forward-looking statements are not statements of historical fact and actual events and results may differ materially from those described in the forward-looking statements as a result of a variety of risks, uncertainties and other factors.

NON-IFRS AND OTHER FINANCIAL MEASURES

This document refers to C1 Operating Costs and All-In Sustaining Costs (AISC) per tonne. These are non-IFRS financial measures and non-IFRS financial ratios. The Company believes that these measures provide additional insight, but these measures are not standardized financial measures prescribed under International Financial Reporting Standards (“IFRS”) and therefore should not be confused with, or used as an alternative for, performance measures calculated according to IFRS. Furthermore, these measures should not be compared with similarly titled measures provided or used by other issuers. The non-IFRS financial measures and non-IFRS financial ratios used in this document are relatively common to the mining industry.

Quality control and data verification protocols

Pegmatite zones were sampled at approximately 1m intervals with sample lengths adjusted to honour geological contacts to aid representativeness. Quality Assurance and Quality Control procedures utilised standard industry practice, using certified reference materials (CRMs) for lithium, field blanks, duplicates sampled in the field and pulp duplicates at the laboratory. CRMs were submitted at a rate of approximately 20%, whereas blanks, duplicates and repeat assay determinations were submitted at a rate of approximately 5%. Samples were bagged and sealed with numbered tags, in order to maintain a chain of custody. The sample bags were transported from the site to either SGS or MSA Labs preparation facilities in Val-d’Or, Québec. Sample preparation at the laboratory (SGS & MSA) entailed crushing, milling and splitting to achieve a 250g sub-sample for assay. Laboratory QC procedures for sample preparation include quality control on checks crushing and milling to ensure representativeness. Analysis was done using Sodium Peroxide fusion followed by combined ICP-AES and ICP-MS analyses (56 elements). Li is reported by the lab and converted to Li2O for reporting using a factor of 2.153. All results included in the MRE passed the QA/QC screening at the lab. Following reporting of results by the laboratory Winsome’s geologists verified that all inserted CRMs and blanks returned results that were within acceptable limits. Data verification is carried out by the Project Geologist on site, and a final verification was performed by the VP Exploration and the geologist responsible for database management. An independent verification was carried out by the QP prior to commencing the MRE.

Open House on the Proposed Adina Lithium Project

On November 12th, we had the pleasure of meeting with the Mistissini community at an open house for the proposed Adina Lithium Project where we had the opportunity to engage with around 100 community members throughout the day. It was a valuable opportunity for meaningful discussions and to gather insights that will inform our future Environmental and Social Impact Assessment.

The Steps of an Environmental and Social Impact Assessment

An Environmental and Social Impact Assessment (ESIA) is a rigorous process designed to evaluate and identify the potential effects of a project, and to minimize or eliminate them before implementation. Its purpose is to protect the natural and social environment, reduce negative impacts, and maximize positive outcomes for both communities and ecosystems. The ESIA is prepared by the project proponent, in collaboration with the project’s stakeholders. The main steps are as follows:

Step 1 – Baseline Studies and Project Description
The process begins with a comprehensive description of existing environmental and social conditions at the project site (natural, social, and economic environments). At the same time, the valued components are defined—these are elements of the environment identified as having particular importance, such as water, air, species at risk, and aspects that are significant to community members and/or land users.
In parallel, the details of the project are defined. This stage helps identify potential interactions between the baseline environment and the proposed project. When interactions between valued components and the project are identified, they are subjected to a more detailed assessment.

Find out what we have done as of November 2025 right here.

Step 2 – Impact Assessment
Potential effects—both positive and negative—are analyzed based on their intensity, duration, and timing. This stage also includes the assessment of cumulative effects, meaning impacts that may result from the interaction between the proposed project and other existing or planned activities in the region, on the valued components.

Step 3 – Mitigation Measures
Concrete measures are proposed to avoid, eliminate, reduce, or compensate for the identified effects. These measures are developed in collaboration with stakeholders and may include modifications to project design, adapted management practices, or environmental restoration initiatives.

Step 4 – Presentation of the Final Project
In light of the analyses and adjustments, an improved version of the project is presented. It incorporates stakeholder concerns and aims to minimize environmental and social effects while promoting responsible and sustainable development.
