Gruyere project - Brief history
Gold Road discovered the mineralisation at Gruyere in H2 2013 with interface rotary air blast drilling. A total of 87,066m have been drilled from 470 drill holes on the project (357 reverse circulation (RC) holes for 41,264m, 73 holes with RC pre-collars for 14,694m RC and 16,506m diamond core tail, plus 40 full diamond drill holes (DDH) for 14,603m) were drilled as part of the feasibility study.
A further six diamond drill holes were completed in 2017 to test the down-dip extension below the Gruyere Resource pit and potentially convert unclassified material to Inferred inventory.
The Gruyere project is 50% owned by Gold Fields Limited after forming a joint venture (JV) with Gold Road Resources in November 2016. The JV, comprising more than 200ha of miscellaneous, exploration and mining tenements on both the Dorothy Hills Shear Zone (DHSZ) and Yamarna Shear Zone (YSZ), includes in addition to Gruyere, declared Mineral Resources and Mineral Reserves for Attila and Alaric. In addition there are three exploration prospects Montagne and Argos on the YSZ and YAM14 on the DHSZ.
2016/2017 exploration expenditures are presented in the Australia regional section.
