Lithium exploration and development company Winsome Resources (ASX:WR1; “Winsome” or “the Company”) is pleased to provide an update on exploration across at its extensive 100% owned project portfolio in the James Bay region of Quebec, Canada. A number of key activities have been completed in advance of the end of the summer field season, in parallel with the recommencement of drilling at Adina, which will enable targets to be refined and ranked for drilling during the winter season. These include mapping and sampling programmes at Adina, Tilly and Cancet and the airborne survey over Adina (including Jackpot).

HIGHLIGHTS

• Exploration continues across Winsome’s highly prospective exploration portfolio, in parallel with ongoing drilling operations at Adina.
• Mineralised pegmatite outcrop discovered at Tilly Project with sampling returning results up to 4.68% Li2O associated with a spodumene-rich zone.
• Airborne survey over Adina completed with detailed interpretation and target generation underway.
• Results of significant exploration field mapping and sampling programmes completed at Adina and Cancet to be integrated with geophysical data to fast track target identification and drill testing to build Winsome’s project pipeline.

“While we are focussed on our intensive drilling campaign at Adina with four rigs in operation and a fifth on the way, it is important that we build up the project portfolio to create a strong foundation for Winsome’s path to development. Our field teams have taken advantage of the last portion of the summer field season to cover a large amount of the project and have identified several new targets worthy of drill testing. Especially pleasing is the identification of a mineralised pegmatite at Tilly, an important piece of our portfolio.”

Tilly Project – Mapping and Sampling

Exploration at Tilly comprised a series of helicopter traverses across the project area and prospecting outcrops identified during flight or from interpretation of high resolution aerial imagery.

In the east of the project a sizeable (400m x 200m) pegmatite outcrop was discovered. Closer inspection and removal of moss identified a spodumene-rich zone. Channel samples were taken along this zone with assays returning a result of 7m at 1.43% Li2O within a total sampled length of 10m. . Further channel sampling was undertaken across this zone and results from these samples are awaited.

Given these encouraging results follow up sampling is planned for this outcrop to try and ascertain the true width and orientation of this zone as well as any extensions and repetitions in the surrounding area ahead of a potential maiden drilling programme at Tilly.

Assay results are also pending from the other samples collected across the Tilly Project.

The Tilly Project was acquired in April for an initial payment of C$70,000 with further share-based payments due upon the project achieving certain milestones (refer ASX Announcement 19 April 2023). Exploration of the Tilly Project has been undertaken as part of exploration at Adina, in parallel with drilling activities. The successful discovery of this pegmatite at Tilly reflects the Company’s systematic exploration approach which has been refined during exploration of the Cancet and Adina properties and led to the discovery of the Adina Main Zone (formerly Jamar).

Adina Project - Airborne Survey

As detailed in the ASX announcement of 29 August 2023 a detailed airborne geophysical survey has been carried out over the Adina Project (including the recently acquired Jackpot Property to the north). The survey was successfully completed with processed datasets now received from the contractor Prospectair Geophysics.

The survey has resolved the magnetic and radiometric responses for Adina in greater detail which will enable an improved geological and structural interpretation to be completed for the project. Interpretation work is currently underway, following which the data will be incorporated in the forthcoming resource modelling exercise as well as to generate targets for follow up and field investigation.
