Aside from its significant investment in drilling the OYG JV has also been conducting a range of activities to evaluate early stage mining opportunities at the near surface, high-grade Grace deposit. This will feed into the broader Youanmi Feasibility Study that has been initiated following the significant resource upgrade for the
Rox Managing Director
"We are very pleased to provide this update on some of the many ancillary exploration and development activities that are happening at Youanmi and to report that the organisation is building out a highly capable team to deliver Feasibility studies on the restart of mining at Youanmi, and ultimately transitioning into development. The Grace orebody has been confirmed as shallow and free-digging in nature. These results support the concept that Grace will be an early contributor to production and cash flow upon the development of the Youanmi project."
Understanding the Grace Deposit
The Grace Deposit is one of several north-south trending lines of mineralisation that occur within accommodation structures within the Youanmi Granite that are related to geological displacement and emplacement of gold mineralisation at the Youanmi gold project.
Gold mineralisation at Grace is hosted in quartz-sericite altered shear zones within granite. It is characterised by high grade, semi-continuous to discontinuous ore shoots.
To better understand the controls on mineralisation and the style and continuity of structure the Company resolved to cut a "window" into the top of the mineralisation by removing the cap rock in the south end of Grace (with an approved POW for that purpose).
Ditchwitch trenches have been cut to: (1) gain further knowledge from long face exposures and (2) yield samples for gravity test work and other grade estimation analysis. Free gold is readily panned from trenches where mineralised zones occur.
Rox's strategy of continuing development of Grace is based on first understanding in detail the more densely drilled and now cut southern area near the
Ripping Trial
A Ripping Trial was conducted on Grace mineralisation and surrounding material to ascertain whether the material will be free dig or require blasting in an early mining scenario.
The trial was conducted in the existing
Figure 5* shows the area where the ripping trial was conducted which was very successful in that the Cat D10 machine was easily able to rip the in-situ material in the old ramp full depth in a single pass.
This information will be applied to any study work on open pit mining in this specific area and geology (i.e Grace oxidised granite to 60 metres depth).

Ongoing Resource and Exploration Drilling
Aside from the above activities at Grace, drilling programs to drive resource growth are progressing very well with 4 drilling rigs on site at present (three diamond and one RC). An aircore rig is due to commence drilling regional targets shortly with further details on the regional exploration program to be released in due course.
A highly experienced Principal Resource Geologist has recently been appointed to oversee the resource development programs.
