ECR Minerals PLC - Australia-focused mineral exploration and development company - Discovers gold bearing quartz veins at the Lolworth project in Queensland, Australia. The project consists of three exploration tenements (EPM27901, EPM27902 and EPM27903) which are operated by LUX Exploration Pty Ltd, a wholly owned subsidiary of ECR. Says "numerous" gold, biobium and REE anomalies have been identified. Adds that a sampling project has just been completed over the ridgelines in Flaggy Creek ridge in Victoria.

Technical Director Adam Jones comments: "The veinlet gold system we have now identified at Flaggy Creek has come about through our systematic approach to the groundwork... We are confident that we have potentially identified a style of gold bearing vein system that we can expect to find throughout the region, and furthermore, we have identified other gold bearing creeks from our stream sampling programme that are in close proximity to and show very similar geological features to the Flaggy Creek area. Coupled with the major soil sampling work completed along strike at the Flaggy Creek outcrop, we are hoping the results from this work may show a much larger system than currently mapped."
