Spectacular Plus 2,000 g/t Au Hit from Dona Maria
Perth, Sep 5, 2016 AEST (ABN Newswire) - Crusader Resources Limited (
ASX:CAS) (CHLXF:OTCMKTS) are pleased to announce visual gold returns spectacular +2,000 g/t Au from Juruena's Dona Maria Prospect.
Highlights
- Spectacular high-grade gold intercept from hole MD-09 at Juruena's Dona Maria prospect:
-- 10m @ 101 g/t Au from 125m in MD-09 including:
- 1m @ 65.36 g/t Au from 126m
- 0.5m @ 10.24 g/t Au from 127m
- 1m @ 24.30 g/t Au from 131m
- 1m @ 104 g/t Au from 132m and
- 0.4m @ 2,009 g/t Au from 133m
- Results provide further evidence of the potential at Dona Maria - central area returning coherent high grades
- Total of 14 holes for 1,787m completed at Dona Maria (results for 5 holes released to date) further results will continue to be announced as they come to hand
This high-grade result is the latest to be received from the Dona Maria prospect and follows on from bonanza grade results announced late last month from hole MD-06 (up dip of MD-09) at Dona Maria including 1.50m @ 141 g/t Au from 45m; 4m @ 8 g/t gold from 96m (including 1m @ 27.99 g/t Au); and 4m @ 3.98 g/t Au from 77m (including 1m @ 11.09 g/t Au) (refer to ASX announcement dated 24 August 2016 see Figures 3 and 4 in the link below).
Commenting on the result, Crusader Resources' Managing Director Rob Smakman said:
"We are obviously really excited to get such an extraordinary hit and even more so that it occurs as part of a broad, highgrade intercept. The central zone at Dona Maria is proving to be the source of some of the best intercepts in the district and indicates a broad, high-grade zone that is continuous and relatively close to surface. I look forward to updating shareholders with the next round of assay results when they come to hand- we are confident the results will help achieve our goals of increasing the confidence level and size of the Dona Maria resource."
Dona Maria Prospect
Dona Maria is located adjacent to the Crentes prospect, approximately 1 kilometre along the Juruena fault zone from Querosene (see Figure 2 in link below). Mineralisation at Dona Maria is perpendicular to the main Crentes trend (WNW) toward the NNW (see Figure 3). There is a broad, relatively shallow garimpo working over the mineralised trend and with the new intercepts along with historical drilling, the central zone appears to show a coherent, high-grade core that is open at depth.
A total of 14 holes for 1,787m were completed at Dona Maria in the 2016 campaign, with results released to date from the first 5 holes.
The central zone of Dona Maria has now returned some of the highest grades of the Juruena district, from both historical drilling as well as results from the current campaign. Twenty-five metres to the north, hole MR-010 (RC hole drilled by Crusader in 2015) returned 8m @ 62.4 g/t Au from 101m downhole and the nearby hole J-07 (historical diamond drilling-Madison) returned 10.5m @ 14.59 g/t Au from 109m and 4.68m @ 64.35 g/t Au from 125m downhole. Geological interpretation of the Dona Maria mineralisation (including the central zone) will advance once assays for all the holes are received and the wireframe updated.
Gold mineralisation at Dona Maria appears to be associated with strongly altered granite and dolerite dykes with the geometry of the alteration zones controlled along a structural corridor. The current interpretation of the structural zone has a north-south orientation dipping steeply to the west. This zone may split and meander, additional results from drilling will be essential for understanding the structural zone geometry. It is important to observe that the structure is not always mineralised with high grades and given the moderate nugget effect of the mineralisation, lower grade zones within the structural zones are expected.
The alteration of the predominantly pink granite is generally observed as pale-green sericite, chlorite with minor quartz and fine grained pyrite. The appearance of the rock when strongly altered is dramatically different to the host rock and as such, the geological modelling of the alteration zone will be relatively well constrained. The mineralised zone is also often accompanied by a dolerite dyke (or dykes), which appear to be using the same structural zone- variable between the footwall and hangingwall contacts. This dolerite is fine grained, non-magnetic, has a dark green appearance and is sometimes mineralised. The core photo in Figure 1 (where the visual gold was observed) has been logged as a strongly altered dolerite dyke, with the gold concentrated along small fractures. There was also minor gold observed at 128.75m, which is logged as moderately altered granite.
Further results from this region are eagerly anticipated and will form a critical part of the planned update to the mineral resource estimate.
About Juruena
The Juruena Project (~400 km2 of contiguous tenements) is located in Central Brazil on the southern fringe of the Amazon Basin. Situated on the western end of the prospective Juruena-Alta Floresta gold belt (estimated to have produced ~7Moz Au), Juruena has been explored extensively by artisanal miners since the 1980's, producing an estimated 500koz of gold.
The current Drilling program at Juruena has now completed a total of 7,722m, with 38 holes at Querosene, 14 holes at Dona Maria, 7 holes at Tomate and 4 holes at Mauro.
