HIGHLIGHTS HILL EAST PROSPECT- Widespread economic grade gold mineralisation further confirmed over at least 1km including 7m at 2.66 g/t from 32m.
- Historic and current drilling is less than 70m deep.
- Significant gold mineralisation occurs in a granite porphyry unit supporting large size potential based on geological analogues. GOLDEN ORB PROSPECT
- Further significant gold intersected at Golden Orb including 5m @ 2.86 g/t Au from 30m with associated silver grades of up to 22.60 g/t Ag. ALAWA PROSPECT
- High grade narrow vein style gold intersected including 1m @ 57.8 g/t confirms potential for a Second Fortune style deposit.
-
Intercept is along strike from previous work and remains open along strike and at depth.
Exterra Resources Limited (ASX:EXC) ("Exterra") is pleased to advise that assay results from the second batch of samples from portions of the first 57 holes from the 76 hole drilling programme at Linden have been received and confirm the presence of multiple mineralised zones at the Hill East, Golden Orb and Alawa prospects.
Assays reported are from selectively sampled portions of the drillholes only, with full assays still pending. Importantly a number of the mineralized intercepts received to date represent incomplete intervals with significant grade at the end of the sampled intervals in several cases.
So far drilling at Hill East has identified multiple zones of ore grade gold intercepts over at least 1km of strike, with significant widths in the oxidized zone, and with primary mineralisation associated with quartz stringers in a sequence of mafic volcanics, sediments and porphyry.
Significantly results at Hill East and Golden Orb confirm gold mineralization hosted within mafic and porphyry lithologies with highly anomalous silver to
22.60 g/t at Golden Orb and arsenic to 1.35% at Hill East.
*Note: All intercepts are downhole widths.
The results confirm the need for further follow-up drilling at Hill East, Golden Orb and Alawa.
Further assay results from drilling completed at Cuckoo Hawk, Pipeline, Second Fortune Extended, Marloo and Mt Linden are expected shortly.
Better results from the latest batch of assays reported include:
- EXAC100 - Hill East: 7 m at 2.66 g/t Au from 32 m, including; 5 m at 3.37 g/t Au from 33 m
- EXRC006 - Golden Orb: 5 m at 2.86 g/t Au from 30 m, including; 3 m at 3.96 g/t Au from 32 m
- EXRC012 - Golden Orb: 2 metres at 3.68 g/t Au from 33 metres
- EXRC030 - Golden Orb: 2 m at 5.22 g/t Au from 11 m, including; 1 m @ 9.31 g/t Au from 11 m
- EXRC049 - Alawa: 2 m at 29.47 g/t Au from 66 m, including; 1 m @ 57.80 g/t Au from 66 m
- EXRC051 - Alawa: 1 m at 8.19 g/t Au from 58 m
These results at Hill East further confirm significant gold mineralisation with associated highly anomalous arsenic over at least 1 km of strike and near surface.
The fact that the mineralisation is associated with porphyry intrusives and with significant quantities of gold being intersected in the oxide and transitional zones highlights the potential for open pittable gold deposits at the Linden Project, in addition to the already identified high grade narrow vein style previously discovered at the Second Fortune Gold Mine and as reported in the current drilling at Alawa.
The Hill East area is covered by lake sediments, soil and calcrete. Mineralisation appears to be related to NE trending quartz veins cross-cutting layering in a sequence of mafic volcanics, sediments and porphyry within a broader north west striking corridor. A major quartz blow to the west and extensive felsic porphyry intrusives indicate a major NW-SE trending fault zone.
The strong gold/arsenic and association and with a porphyry intrusive event is supports the potential for a large scale system with a number of geological analogues in the Laverton Tectonic Zone. Further field work is underway to determine the significance of the gold/arsenic/porphyry association and follow up drilling currently being planned.
