Looking back at public records in slightly more detail and once again referencing a previous post (-37101533) :
The 2017 GCY Annual Report notes competent persons who assessed GCY resources st Dalgaranga are :
-RungePincockMinarco - a highly regarded global consultancy.
If you search the report you will see RPM references the 07/08/17 “DALGARANGA GOLD PROJECT – SLY FOX RESOURCE AND EXPLORATION UPDATE”
(Sly Fox is/was a deposit (now mined out) which seems to have proved as was estimated by the RPM analyst who personally supervised all data collection at that deposit.)
As I read it ( on searching for the report’s competentpersonsstatement), all drilling and exploration data on Dalgaranga was compiled by Gascoyne’s Chief Geologist, Julian Goldsworthy.
-The 2017 annual report also states the Dalgaranga ore reserve was estimated by the principal of Mining Focus who in turn references the 21/06/17 announcement; “Dalgaranga Gold Project Development Update” (here).
(FWIW the competent persons listed in this update are RPM - now directly referencing the work of Elemental Geology along with old Equigold data for Glenburgh as per the 24/07/14 “HIGH GRADE DOMAINS WITHIN UPDATED GLENBURGH MINERAL RESOURCE”
Please do your own research as this is just my personal idea of things through tracking back through a series of references .
I have provided links to all the information I looked at .
