Exceptional Drill Results at Great Western Gold Project
Terrain Minerals Limited (ASX: TMX) is very pleased to announce these exceptional drilling results from the December 2016 Great Western - Stage 1 drilling campaign comprising of 18 RC holes for 1,308 metres. Refer to Diagram 1 and Table 1. This program has achieved both desired outcomes and returned wider intersections and higher grade than expected in many holes. Firstly; Infill drilling at the eastern end aimed at lifting the majority of the 42% of the JORC 2012 resource in this location (see ASX release dated 24/08/2015) from Inferred to Indicated status. All holes intersected mineralisation. Some of the better intersections include:GWRC0120 - 6m @ 1.56g/t Au from 37m down hole
GWRC0121 - 5m @ 6.98g/t Au from 88m down hole
GWRC0123 - 2m @ 12.1g/t Au from 82m down hole
& 2m @ 24.4g/t Au from 99m down hole
GWRC0124 - 2m @ 3.12g/t Au from 26m down hole
Secondly; The remaining holes targeted the previously poorly tested shallow mineralised zones in and around historical workings. Some of the better intersections include:GWRC0126 - 7m @ 4.43g/t Au from 18m down hole
GWRC0129 - 3m @ 3.92g/t Au from 27m down hole
GWRC0130 - 8m @ 3.20g/t Au from 25m down hole
GWRC0131 - 3m @ 26.6g/t Au from 8m down hole
GWRC0132 - 3m @ 3.76g/t Au from 14m down hole
GWRC0135 - 5m @ 1.97g/t Au from 13m down hole
The above shallower intersections have the potential to improve the grade response in the mineral resource model (when updated) in this location and have a major effect to Great Western's required start-up capital, with the possibility of bringing forward positive cash flow in the current mining studies.
These successful results will now be incorporated into an updated JORC resource model. The updated model will then be incorporated into current ongoing scoping studies. The market will be updated accordingly.
A total of 18 RC holes for 1,308m were drilled in December 2016 (for drill hole details see Table 1 and Diagram 1). The aim of the programme was twofold;
7 holes for 654m targeted mineralisation on the eastern portion of the currently defined resource to increase confidence in continuity of the lodes and lift 42% of the resources from inferred to indicated status so they can be incorporated into the current scoping studies.
11 holes for 354m were completed to test previously inadequately defined shallow oxide zones in and around the historical workings.
All drilling intersected the targeted zones in the expected positions. Significant mineralised intersections (see Table 1) were associated with quartz veining and sulphides (or their weathered equivalents). Host lithologies comprised granite or dolerite as expected.
The above results were all generated from standard 1m intervals. A series of composite samples that returned low grade mineralisation will be resampled for a total of 142 (1m samples) and, if significant results emerge, these will be released in due course.
The high grade intersections within the oxide zone are considered very encouraging. It is anticipated that results from the shallow oxide drilling has the potential to enhance the modelled grade in the mineral resource when updated in this location and potentially have a significant effect to Great Western's required start-up capital due to a possible increase in grade within these upper zones. These results have the potential to challenge all past assumptions.
These successful results will now be incorporated into an updated JORC resource model. The updated model will then be incorporated into current ongoing scoping studies. The market will be updated as this work progresses accordingly.
Other:
In addition, several grab samples were also taken over the two historic heap leach pads containing historic battery sands. Results indicate additional follow up work is warranted. A more detailed sample program is being designed and will be executed in due course.
The drilling has also captured sufficient sample material across all ore types to be used for metallurgical analysis and ensuring robust QA/QC protocols and analysis occur. These samples are being stored at a secure location. All efforts are now focussed around advancing the Great Western Gold project towards production.
