NOTE: all ASX penny stocks in the Sandstone region have been actively exploring their respective projects despite of lower grade. AME is the most hopeful given WGX offered 7c a share in 2020, and is still a large shareholder. MDI would have asked AME first before it sold its tenements, resources and infrastructure to AUN. ZER holds HRN perhaps at an average cost below 30c, it would have to merge with GML for any chance of development.
