The 100%-owned Memot project contains indicated and inferred resources of 45.0 million tonnes grading 1.2 grams per tonne gold for 1.7 million ounces. The infill drilling used a tight grid of 12.5 by 25.0 metres, suitable for resource delineation and reserve development as the project approaches a development decision.

Significant intercepts from Memot included 2 metres at 32.11 grams per tonne gold from 38 metres depth, 4 metres at 13.83 grams per tonne from 14 metres, and 13 metres at 3.93 grams per tonne from 4 metres, indicating shallow mineralisation. Additional results comprised 3 metres at 14.90 grams per tonne from 7 metres and 9 metres at 3.02 grams per tonne from 33 metres. Completing this infill program marks a critical milestone toward advancing Memot’s development readiness, providing technical data to support economic and operational planning.

Anchor Prospect Exploration Targets Potential Satellite Deposit to Memot Project

During the quarter, Emerald rationalized tenure in Cambodia, reducing the Snuol Exploration Licence from 198 square kilometres to 13.44 square kilometres. This adjustment prepares for an Industrial Mining Licence application over the Anchor Prospect, which is being evaluated as a potential satellite resource to supply ore to the 1.7-million-ounce Memot Gold Project. Developing satellite deposits to supplement a central processing facility is a value-enhancing strategy, improving capital infrastructure utilization and operational capacity.

The Anchor Prospect is defined by a 1.5-kilometre by 1.5-kilometre gold-in-soil anomaly linked to gradient array induced polarization chargeability responses. Historical and company drilling totals 5,344 metres from 47 historical holes and 8,121 metres from 81 company drill holes. Results show structurally controlled precious and base metal mineralisation along a roughly 500-metre corridor. Notable intercepts include 6 metres at 8.28 grams per tonne gold from 12 metres, 5 metres at 6.23 grams per tonne from 14 metres, and 4.3 metres at 4.76 grams per tonne from 147.2 metres. Polymetallic intercepts include 4 metres at 7.72 grams per tonne gold, 180 grams per tonne silver, 0.50% copper, 0.24% lead, and 2.29% zinc from 72 metres. Further drilling is planned to test extensions of the mineralised corridor and other untested anomalies.
