Highlights
- Platina Resources has completed 10,809m of aircore drilling across 220 holes at the Mt McKenna Gold Project.
- Drilling identified a new mineralised corridor extending more than 1km at the Granite Well East Prospect, supported by multiple gold intercepts.
- Results at the Black Rock Prospect defined a coherent mineralised structure exceeding 800m, with elevated arsenic values and several anomalous gold intersections.
- The company secured AUD 109,200 in co-funding from the Western Australian Government to support a 13-hole RC drilling program targeting deeper mineralisation.
- Follow-up RC drilling later this year aims to test high-priority targets and advance exploration across the project.
Platina Resources Limited (ASX:PGM) has reported the discovery of new gold zones at the Granite Well East Prospect within its Mt McKenna Gold Project in Western Australia's Laverton Gold District . The findings follow the completion of 10,809m of aircore drilling across 220 holes over two exploration phases, with results highlighting a new mineralised corridor and multiple gold intercepts across key target areas.
Granite Well East Delivers Multiple Gold Intercepts
Drilling at Targets 4 and 5 returned several notable gold intersections, including-
- 1m @ 7.10g/t Au from 40m (MMKAC0239), ending 1m above the bottom of hole (BOH);
- 4m @ 1.11g/t Au from 12m (MMKAC0240), associated with a strong arsenic anomaly;
- 7m @ 0.61g/t Au from 36m, including 2m @ 1.41g/t Au from 40m (MMKAC0240), with mineralisation continuing to the bottom of hole; and
- 4m @ 0.93g/t Au from 52m, including 3m @ 1.13g/t Au from 52m (MMKAC0194), ending at the bottom of hole.
The drilling campaign has identified a new mineralised corridor extending over more than 1km strike at the Granite Well East Prospect , covering Targets 4 and 5 .
Mineralised Structure Defined at Black Rock Prospect
At Target 2 , drilling returned-
- 4m @ 4.69g/t Au from 16m (MMKAC0162) along the eastern mafic-granite contact;
- 4m @ 0.33g/t Au from 28m (MMKAC0129) within saprock adjacent to a strong arsenic anomaly, further supporting planned RC drill testing;
- 1m @ 0.27g/t Au from 39m (MMKAC0305), ending at the bottom of hole;
- 4m @ 0.34g/t Au from 48m (MMKAC0339); and
Results from the drilling campaign outlined a north-northeast trending mineralised structure spanning over 800m at the Black Rock Prospect , characterised by elevated arsenic values and several anomalous gold intersections .
Government Grant to Support Next Drilling Phase
The company has been awarded AUD 109,200 under the Western Australian Government's Co-funded Exploration Drilling Program . The funding will support a 13-hole RC drilling program at Target 2 , where the company plans to test the deeper extensions of mineralised structures identified through the recent aircore drilling campaign and gravity surveys. The RC drilling program will form part of the follow-up exploration campaign scheduled for later this year .
