Blue Mountain Project

Standing out from all of our other successes in the past two years is Blue Mountain, located 95km south-west of the port of Gladstone in Central Queensland. Acquired in 2023, ECR began drilling operations in 2025.

The project is within a region where gold and copper mineralisation are present. The project currently includes an alluvial gold deposit within Denny Gully, which is reported to contain up to and potentially over 100,000 ozs. The upper source regions of this alluvial deposit are of particular interest.

Previous testing of the alluvial ground on South Kariboe Creek and Denny’s Gully is evidenced by the remains of old pits within the creek. A historic (non-JORC) report within this region for the South Kariboe Creek and Denny’s Gully prepared by Normin Consultants Pty Ltd estimates a potential 1,426,800 bank cubic metre (b.c.m) at 0.60 grammes per b.c.m. implying 27,526 oz Au.

In July 2024 we completed eight test trenches on the upper reaches of South Kariboe Creek.  A total of 15.4 cubic metres of alluvial gravel was processed through a pilot trommel wash plant, yielding 9.95 grammes of visible gold, an overall average of 1.55 grammes per b.c.m. which was significantly higher than previous estimates. 

In addition, six bulk samples of concentrates were submitted for laboratory analysis and the best results included 192.15 g/t, 97.40 g/t and 33.19 g/t Au within these concentrates.

With the success of these results, we commissioned Gekko Systems to carry out a GRG test and sighter leach test on samples of the ore collected at Blue Mountain.  The GRG test work demonstrated a recovery rate of 91.7% gold into 0.40% of the mass.  These findings suggest that the ore located at Blue Mountain is suitable for gravity concentration using a batch centrifugal concentrator (“BCC”).  

Gekko Systems is a global leader in mineral processing solutions with a particular focus in gravity separation, intensive leaching and pre-concentration.

During July and August 2025, ECR drilled almost 400 holes across the Lower Patterson, Windmill and Upper Kariboe Creek areas at Blue Mountain using a reverse circulation drilling rig. Visible gold has been confirmed in multiple zones and preliminary results were announced on 15 September 2025 confirming extensive gold mineralisation in the Lower Patterson area.

Unlike ECR’s historical focus, the Blue Mountain Project is based on an alluvial gold system.  Gold is therefore found at or near the surface, meaning that the mining techniques used to extract any minerals are not associated with high capital expenditure that other projects may have, for example, where higher gold grades are located at great depth.

Future production at Blue Mountain would be undertaken through gravity concentration of near-surface ore.
