- Final results from assays are presented for the first 10 diamond drill holes (2,483 metres) from the phase four drilling programme at Ndablama. Drilling was undertaken on the down dip extensions to the current Inferred Mineral Resource of 451,000 ounces at 2.1 g/t Au (using a 0.5 g/t cut-off). Intercepts include:
3.0 g/t over 33 metres from 109 metres
3.5 g/t over 18 metres from 96 metres
1.2 g/t over 33 metres from 99 metres
1.3 g/t over 24 metres from 107 metres
- The latest results confirm continuity of the mineralised system down dip for a further 130 metres with intercepts commencing at 90 metres below surface. The mineralised body is open in all directions.
- Geological mapping, soil geochemistry, trenching, geophysics and previous reconnaissance drilling have outlined a five kilometre mineralised structural zone which dips shallowly to the west and locates at the sheared and altered contact between granite and metavolcanics. This zone is referred to as the Pressure Shadow Corridor. It is associated with extensive bedrock and alluvial artisanal gold mining.
- The phase four drilling programme is designed to expand the current Inferred Resource both down dip and along strike. A total of 50 diamond drill holes for approximately 10,000 metres are planned over a target area that strikes north for one kilometre, extends down dip for vertical depths of 250 metres below surface and encompasses targets referred to as Ndablama Central and Ndablama North. The Company’s exploration team continues to actively explore the Pressure Shadow Corridor. Drilling re-commenced in mid-January following the festive break.
- Trenching and detailed sampling is in progress in the Ndablama Far North and Ndablama South areas prior to the commencement of reconnaissance drilling.
Commenting on the latest Ndablama drilling results, David Reading, President and Chief Executive Officer of Aureus Mining, said:
“The recent Ndablama drilling results highlights the excellent continuity of this deposit and we are on track to deliver an expanded resource during the current field season. Our work along the five kilometre corridor is demonstrating that we are dealing with an extensive mineralised system and we are very excited about the opportunity that this new goldfield presents for our shareholders”.
Details relating to the latest drilling results and the pressure shadow corridor are illustrated in the following diagrams:
The Ndablama gold target is located within the Northern Block of the Company’s 457 km2, 100% owned, Bea Mountain Mining licence in Liberia, and is situated approximately 40 kilometres north-east of Aureus’ flagship New Liberty Gold project. To date a total of 64 diamond drill holes covering 10,797 metres and 63 trenches for 3,967 metres have been completed at the Ndablama gold target with the majority of this drilling focused on the Ndablama Central area.
The mineralisation is located within a sheared package of ultramafic and mafic rocks intercalated within a gneiss sequence overlying a granite batholith. The mineralisation has a shallow westerly dip reaching on average 30° and striking to the north. It has been drill investigated to a maximal vertical depth of 130 metres below surface. It remains open along strike and down dip.
The latest phase four drilling results are presented in Table 1 below:
|Borehole ID||From (m)||To (m)||Hole Length (m)||Au (g/t)|
|Assay grade data is un-cut|
Drilling to date has shown that mineralisation is hosted in sheared and altered metavolcanics which dips shallowly to the west at approximately 30o. Mineralisation is associated with phlogopite, chlorite alteration and disseminated pyrrhotite.
The phase four drill results reported in this release have extended the known mineralisation down dip by an extra 150 metres, with mineralisation continuing down to a vertical depth of 130 metres. The drilling has highlighted the continuity of the mineralisation 100 metres further to the north of the maiden resource of 451,000 at 2.1g/t, as reported during the Company’s Press Release of 11 November 2013. The mineralisation remains open at depth and along strike.
The phase four drill programme is ongoing within the Ndablama North and Central zones; with the aim of expanding the current NI 43-101 Inferred Resource of 451,000 oz grading 2.1 g/t Au (using a 0.5 g/t cut-off). Drilling recommenced in mid-January and will continue throughout the remainder of the current field season. To date only ten holes from a planned fifty hole programme have been completed. The drill programme will total 50 diamond drill holes for approximately 10,000 metres, planned over a target area that strikes north for one kilometre, extends down dip for vertical depths of 250 metres below surface and encompasses the targets referred to as Ndablama Central and Ndablama North.
At Ndablama North Zone, gold mineralisation has been traced by trenching over a further one kilometre in a northerly direction and includes additional diamond drilling over the first 300 metres. Results for this zone were presented in the Company’s press release of 10 September 2012. Highlights of this exploration work include:
- 19 metres at 1.1 g/t from a depth of 16 metres in borehole NDD026
- 8 metres at 1.1 g/t from a depth of 4 metres in borehole NDD014
- 82 metres at 2.1 g/t from trench NT17
- 9 metres at 2.1 g/t from trench NT62
Ndablama is situated within a five kilometre pressure shadow zone and is an area of extensive artisanal gold activity
The Ndablama gold project locates within a five kilometre mineralised, structural zone which dips shallowly to the west and occurs at the altered and sheared geological contact between metavolcanic rocks (ultramafic and mafic units) and granite. This zone is referred to as the Pressure Shadow Corridor, and extends from Ndablama Far North to Leopard Rock South. It is associated with extensive bedrock and alluvial artisanal gold mining. To date less than 20% of the pressure shadow corridor has been drill tested.
Resource expansion work is currently being undertaken at Ndablama Central and at a portion of Ndablama North. To the north and south of the resource expansion area the Company is focussed on undertaking trenching, rock sampling and additional reconnaissance drilling in order to better understand the mineralised system in these areas and to define additional targets for follow up drilling programmes.
Eight hundred metres south east of Ndablama, the Leopard Rock target has been drilled at a reconnaissance level and demonstrated shallow westerly dipping gold mineralisation which is very similar to Ndablama. This drilling has extended the mineralisation system a further one kilometre to the south east. Soil anomalies and artisanal activity indicate that it can be extended for another kilometre south east beyond the known drilling.
Sampling and QA / QC
Drill core is split on site and samples are despatched under custody to the SGS Laboratory in in Monrovia.
All samples collected by Aureus are analysed using aqua regia digestion and fire assay analysis with an atomic absorption finish. Assay quality control protocols include the submission of commercial certified reference standards, blanks, field duplicates, pulp duplicates and umpire control samples. Standards are inserted into the sample stream at a frequency of 1 in 10. All other quality control samples are submitted at a frequency of 1 in 20. Assay quality control samples are reviewed on a monthly basis. Aureus also submits samples for screened fire assay analysis.
