ECR Minerals (LSE:ECR) has identified a previously unreported gold-bearing quartz reef within the ventilation development at the Maddens Mine, part of its Maddens Gold Project in North Queensland.
The company has named the structure Jack’s Reef and described it as a consistent, foliation-parallel quartz reef approximately 50 centimetres wide containing visible gold.
According to ECR, the location of the reef indicates a potential structural connection between the historic Maddens Mine workings and the Maddens Northern Lode.
ECR Evaluates Ramp-and-Flat Vein Model
ECR believes Jack’s Reef may form part of a wider ramp-and-flat vein system. The company said this type of structure can create dilatant zones that may host higher-grade gold mineralisation.
The interpretation has led ECR to revise its structural model for the area. The company believes the model may indicate continuity of gold-bearing structures beyond the previously assumed limits of historic mine development.
Further exploration will be required to determine the extent, continuity and grades associated with the newly identified structure.
Existing underground infrastructure at Maddens Mine provides access for follow-up work without requiring substantial initial development, according to the company.
Jack’s Reef Material Stockpiled for Processing
Material extracted from Jack’s Reef has already been stockpiled at surface, with processing expected to begin later this month.
ECR said the discovery has also identified additional targets for underground and surface drilling around Maddens Mine and the Maddens Northern Lode.
The company plans to use the revised geological and structural interpretation to investigate potential connections between mineralised zones across the wider project tenement.
More about ECR Minerals PLC
ECR Minerals PLC is a London-listed exploration and development company focused on gold projects in Australia.
The company holds a 50% interest in the Maddens Gold Project in North Queensland, where existing underground infrastructure provides access for exploration and production-related activities.
The wider project contains several historic mines and workings that have received limited modern systematic exploration. ECR is using structural modelling, geological work and underground access to evaluate the extent and continuity of gold mineralisation across the property.
