Avalon Advanced intersects 1.54% Li2O over 136.95m at Big Whopper Deposit
Avalon Advanced Materials Inc. in conjunction with its Joint-Venture partner SCR-Sibelco NV, is pleased to report the second and final batch of drill results for the 2024 winter drill campaign from the Separation Rapids Project in Kenora. The 2024 winter drill campaign was conducted by the Joint Venture Company Separation Rapids Ltd., which is 60% owned by Sibelco and 40% owned by Avalon.
The results represent 199 assay results from 5 diamond drill holes completed as part of the 2024 expansion and infill drill campaign at the current 750m strike length Big Whopper Deposit (See Figure 2). The drill program was intended to upgrade the 2023 Mineral Resource Estimation classification as well as to expand the mineral resources.
Drill Highlights includes from Big Whopper Deposit:
- SR24-121 intersected 1.54% Li2O over 136.95 meters from 321.00m
- including 2.28% Li2O over 4.00 meters from 421.00m
- SR24-119 intersected 1.87% Li2O over 17.15 meters from 284.40m
- SR24-120 intersected 1.60% Li2O over 12.80 meters from 66.15m
All quoted intersections comprise a cutoff grade of 0.5% Li2O. All significant assay intervals with true widths are reported in Table 1.
Scott Monteith, CEO and Director, commented, "These exceptional results taken over very long intervals are a clear indication of the highly efficient drilling program by our JV Partner Sibelco. Another long, massive intercept on Hole SR24-121 will be key to growing the mineral resource base. What is exceptionally exciting is the depth potential, with hole SR24-121 effectively intersecting 136.95m mineralization from 321m downhole.
This hole supports our belief that we have barely begun to uncover the potential of lithium resources at the Separation Rapids deposit. With our objectives for the 2024 winter drilling campaign accomplished, we look forward to the upcoming Mineral Resource Estimate."
The results from the second batch of the 2024 drill campaign continues to identify mineralization below the current resource pit shell with drill hole SR24-121 intersecting values ≥0.5% Li2O over a 136-meter interval, opening the main zone at depth. See Figure 3. Eastern drilling shows promise of possible extension to the current resource boundaries. See Figure 4.
An updated Mineral Resource Estimate (MRE) is planned for Q3 of 2024 which will include results of the 2024 winter drill campaign. Total drill meterage will increase from 18,500 meters of drilling to 26,241 meters.
A property wide mapping and sampling program was completed in late July 2024 with a focus on satellite targets and areas of limited geological data for further evaluation of the promising potential on the property. This mapping program covered approximately 5 kilometers along strike and is currently being modelled and interpreted for further evaluation.

Four drill holes returned significant drill intercepts greater >/=0.5% Li2O.
