wait for how many years

Only my opinion.
Its a long long wait for the Bio Heap
I was a shareholder since early days and stayed with them for 3yrs with the so called tests, and they are still doing tests.
Only my opinion but I have no faith in the Sherlock bay bioheap processing. Compare them to Caldag project and they advanced far further into production in a tougher terrain, used more acid leaching. Could never get a straight answer from management where I could view these tests in Perth.
Strongly Believe in BioHeap processing especially using the native bacteria as part of processing, however not with ARH.
