New Targets At Adina From Gravity Survey With Airborne Survey Commenced

Lithium exploration and development company Winsome Resources (ASX:WR1; “Winsome” or “the Company”) is pleased to announce new gravity data as well as the commencement of an airborne geophysical survey at its 100% owned Adina Project in the James Bay region of Quebec, Canada. This is in conjunction with resource definition drilling at Adina which recommenced approximately ten days ago.

HIGHLIGHTS

• A high resolution airborne magnetic and radiometric survey at 50m line spacing has commenced over the Adina project area (including Jackpot)
  
• High resolution magnetic data aims to better detail sub-surface geology and structural controls, which will assist in linking Adina Main to other mineralised occurrences on the project
• Radiometric data will also be collected given the survey spacing will be detailed enough to detect a response from large, exposed pegmatite outcrops
• New data from gravity stations collected thus far in 2023 continues to define anomalies and targets for follow up drilling later in 2023
• Encouraging target along trend from Main Zone, parallel to the Ridge Zone where 2018 drilling intersected lithium mineralisation
• Drilling underway again at Adina with further drill rigs being mobilised

Radiometric data will also be collected in the survey. Pegmatite dykes around Adina are expected to give an elevated response in radiometric surveys due to increased contents of Potassium (K) compared to the greenstones. However, since outcrops in the area are frequently covered by overgrowth, a close spaced survey such as the one being carried out is required to detect exposures of 100 – 200m in size.

It is anticipated more pegmatite targets across Adina will be identified from the radiometric data for field checking through the 2023 field season, especially in areas not yet traversed by the field mapping team. This will be especially useful for the recently acquired Jackpot property³, where initial field work will commence shortly.

The survey will be carried out by Prospectair Geosurveys using a Eurocopter EC120 helicopter. Data will be collected on 50 metres line spacing with tie lines flown at 500m intervals as shown in Figure 1.

As detailed previously⁴ close spaced ground gravity is especially effective at Adina due to the density contrast between pegmatites and the amphibolites which have been intruded by the pegmatite swarms. Figure 1 shows an image of ground gravity data updated with new data available from the portion of the 2023 survey completed to date which highlights several encouraging targets for evaluation by field mapping and drilling. Targets have been defined to the south of the Ridge Zone, which appear to run parallel to the trend of mineralisation and broadly on trend with the Main Zone where recent drilling has been focussed.

Interpretation of gravity data and target generation, as well as input into the airborne survey, was undertaken by Perth-based consultancy NewGenGeo Pty Ltd, which specialises in the application of geophysics to pegmatite exploration. Gravity data collection has been halted due to the recent fire emergency in the area surrounding Adina.

WINSOME’S MANAGING DIRECTOR CHRIS EVANS SAID:

“The gravity data continues to provide us with compelling targets for drilling outside the areas of known mineralisation at Adina. We look forward to the results of the airborne survey and the potential to identify even more targets within the project area. The discovery of the Footwall Zone in recent months has been a step change for Adina and the opportunity to discover further pegmatite swarms is an exciting proposition for the development of the project.”
