Unlocking Gold Assets in the Pilbara

About Us

Hardey Resources (ASX:HDY) is a publicly listed, junior mineral resources company focused on the exploration and development of key demand-driven commodities.

The Company’s current focus is in discovering Paleo-placer Witwatersrand style mineralisation in the Pilbara region of Western Australia.

ShowcaseOur Latest Projects

The Grace Project tenements cover 56 square kilometres located immediately south of the Telfer copper gold mine.

The tenements are considered highly prospective due to both the area having a disrupted exploration history and the similarities to other projects surrendered by Newcrest in the Telfer region, which are achieving outstanding results for ASX listed companies, namely Antipa Minerals and Encounter Resources. Hardey has obtained a digital exploration database for the tenements and is currently undertaking a desktop review. The database includes details of previous surface and drill hole geochemical information. Newcrest have drilled the tenement to an average depth of <100m, with key strucutral trends controlling mineralisation evident. Previous drilling was not orientated to intersect the mineralised trends with significant targets not yet tested. The size and structural trends of known gold mineralisation are considered to not have been fully evaluated and demostrate the potential to represent significant gold mineralisation.

The mineralisation intersected from historic drilling occurs in hydrothermal breccias over a 1km strike along the regional Bemm Shear and dolomite/dolerite contact. The previous shallow drilling completed combined with the suboptimum drill hole orientation is considered to not have fully tested the prospect. Hardey anticipates that its exploration program will focus on the higher-grade gold veins and shallow dipping stacked vein sets at Grace and comprise of further mapping, IP surveys followed by RC and Diamond drilling in 2018.

Hardey is intending to focus the exploration expenditure on targeted drilling and geophysical surveys to further build confidence in the areas of known mineralisation and test extensions of mineralisation based on further synthesis of exploration data and reassessment of results as exploration progresses.

…the contrasting rock competencies between the dolerites and dolomites act as sites where deformation and subsequently metasomatism was greatest. These sites focused the mineralising fluids. This theory was proved by drillhole GPC9206 and hence, the linear ‘intrusive trend’ needs to be followed up. The mineralised fluid first penetrated the igneous country rock contact, were then diverted out along cross cutting structures into the hangingwall dolomites. The mineralisation was then trapped in favourable structural sites such as overturned anticline hinges or shears (Newcrest, a37495).

…Additional drilling is required within the current mineralised area to validate orientation of interpretated horizons and along strike, following the Grace Intrusive Trend. The dolerites were intruded prior to deformation, hydrothermal alteration and mineralisation. The competency difference between the country rock and the dolerites aided in the focusing of the metasomatic fluids, hydro-brecciation and mineralisation. Sites where cross-cutting, westerly dipping structures also occur may correspond to ‘blowouts’. Hence, exploration diamond drillholes are required to target the prospective intrusive contacts. The strike extent to the mineralisation probably incorporates the contact area as well. The mineralisation at Grace is just beginning to be understood. The size of the lag anomaly and the mimicking Intrusive Trend indicate that the potential of the area is enormous. It has been established that the mineralisation occurs in pods and it’s just a matter of drilling before additional pods are found (Newcrest, a37495).
