Kingwest Resources Ltd (ASX:KWR) has hit high-grade gold in recent drilling at Lady Shenton prospect within the Menzies Gold Project (MGP) in Western Australia, further indicating the potential to delineate additional panels of high-grade ore.
The deepest drill hole at the high-grade Lady Shenton historic mine returned high-grade gold about 100 metres down-plunge from the nearest drill hole.
Lady Shenton had underground production of 191,000 ounces of gold at 32 g/t.
The drilling program was designed to understand the geological setting, develop a structural model for the control of gold mineralisation, confirm and extend high-grade gold intersections, and validate exploration potential to increase near-surface, historical JORC resources.
Access permits to Lady Shenton and First Hit prospects were obtained recently during the drilling program, which has allowed drilling to confirm extensions of high-grade gold at Lady Shenton and to shortly test for extensions of historical intercepts including at First Hit.
These include 7 metres at 42.8 g/t from 100 metres and 6 metres at 16.3 g/t from 74 metres.
Five deposits targeted
The program, which focused on five deposits - Selkirk, Pericles, Lady Shenton, Yunndaga and First Hit - has been completed with 23 holes for 6,440 metres.
Highlights of the tranche-2 drilling results include:
- 1.5 metres at 14.33 g/t gold from 291.5 metres, including 0.3 metres at 71.3 g/t from 292.1 metres in KWD027, an extension of the historically mined lode 100 metres below Lady Shenton;
- 2.9 metres at 5.84 from 52.1 metres, including 0.3 metres at 45.8 g/t from 52.1 metres in KWD027, the discovery of a new lode west of Lady Shenton; and
- 2.4 metres at 14.75 g/t from 562 metres in hole DDH1 confirmed from previously unreported historical drilling at Yunndaga (deepest drilling in project) and KWR drilling of 2.0 metres at 6.44 g/t from 165.0 metres, including 0.64 metres at 15.40 g/t from 165.70 metres in KWD012 (Yunndaga).
Further results are expected before the end of the year and the drilling program is anticipated to be completed within the next two weeks.
Review of data
A comprehensive review of all open file data is ongoing and includes exploration and mining data as well as reports available at the Department of Mines, Industry Regulation and Safety (DMIRS).
This has revealed that more than 5,000 historical workings exist within the MGP.
Although many of these are shallow prospector workings, many deeper shafts and workings identify mineralised trends outside the largest historical producing mines and these trends need to be followed up.
Updated 3D geological models are being developed with surface geological mapping and logged diamond core data being integrated into the models.
Detailed aeromagnetic data will also be compared to the locations of the workings in order to better determine the structural controls of the mineralised lodes and trends.
A detailed aeromagnetic survey over the MGP has been completed with 5,718-line kilometres flown at 25-metre line spacing.
The survey was flown by MAGPSEC Airborne Surveys Pty Ltd.
Data will be interpreted in December and integrated with updated 3D geological models that are being compiled which, in turn, will include detailed geological information being collected in the current diamond drilling program.
The objective of the survey was to delineate geological units and significant structures within and between know mineralised deposits in order to define the main structural controls and to help predict the most likely locations of undiscovered mineralised lodes.
The 25-metre line spacing gives considerably improved magnetic and radiometric images compared to the previous 100-metre line spaced government data.
