Ora Gold Limited (ASX: OAU) has hit high-grade gold mineralisation at the eastern end of the ore body in RC drilling at the Crown Prince Prospect part of Ora’s Garden Gully Gold Project in WA.
The advanced Crown Prince Prospect continues to be a focus area for the company to prove up development ready ounces. Crown Prince comprises the Southeastern and Main Zones as mineralised zones which are in close proximity to each other and commence at shallow depths.
High-grade gold assay results include results from hole OGGRC710. Importantly this hole successfully targeted depth extensions of the eastern area of Southeastern Zone mineralisation below OGGRC662. The intersection sits just within the boundary of the current resource block model (northeastern end of the deposit) and is likely to result in a grade uplift and strike and dip extensions when incorporated into future models.
“Drilling from the Southeastern Zone (SEZ) continues to show the potential for new high-grade zones to be discovered,” CEO Alex Passmore said.
“This area of the resource has previously been modelled as modest grade and width. We look forward to incorporating these results which show high grades down the profile with good continuity to depth into an updated Crown Prince MRE, which is expected to be finalised in a few months from now.”
The best new intersection returned in OGGRC710 is 6.0m at 28.8g/t Au from 163m including 2.0m at 76.62g/t Au from 164m and the mineralization is open at depth. The hole will be extended in future programs as it ended in mineralisation.
The intersection is at the eastern end of the existing resource model and is expected to increase the grade profile in this area.
This is down-dip of the previously intersected high grade within OGGRC662 (15m at 9.91g/t Au from 88m) and adds confidence to the SEZ mineralisation in this area.
At the eastern end of the Southeastern Zone, the footwall to the mineralised structure is strongly deformed and displays a wide alteration zone which contains multiple high-grade veins.
Hole OGGRC710 will be extended as it ended in mineralisation due to drilling difficulties. Diamond drilling is planned (parallel to OGGRC682) to take structural data in this area.
Resource development work continues at Crown Prince with new mineralised zones being drilled out in sufficient detail to be included in an updated resource estimate due for completion in the middle of the September quarter.
Preliminary project development work has commenced with key consultants appointed for the preparation of a mining proposal for Crown Prince. Preliminary work on metallurgy, hydrogeology and geotechnical that the company has already completed is being used to expedite the proposal preparation timeline.
