Cardinal Resources: New Drill Season Hits High-Grade Shallow Gold at Ndongo East
(firmenpresse) - Cardinal Resources: New Drill Season Hits High-Grade Shallow Gold at Ndongo East
Highlights
- Significant new high-grade gold intersections from Ndongo East include:
- 3m (at) 29.3 g/t Au from 45m in NDDD036
- 3m (at) 4.1 g/t Au from 122m in NDDD037
- Previous high-grade gold intersections from Ndongo East included:
- 9m (at) 23.3 g/t Au from 60m in NDRC248*
- 7m (at) 4.4 g/t Au from 14m in NDRC216*
- 6m (at) 12.6 g/t Au from 2m in NDRC275*
- Gold mineralisation demonstrated over a strike length of approximately 1.2km at Ndongo East;
- RC drilling has encountered multiple intercepts of near-surface mineralisation;
- Further assay results expected from four diamond holes completed along the NE-SW structure that hosts high-grade gold discovered to date;
- Diamond drilling is ongoing and will continue to evaluate the strike and depth extension of the Ndongo East mineralised system;
- Multiple additional parallel mineralised structures striking NE-SW remain to be evaluated by drilling and provide high priority drill targets;
- Prospectivity of the area is greatly enhanced due to its proximity to the prolific Nangodi Shear Zone which is known to host major economic gold mineralisation - including the historic Nangodi Gold Mine.

28 November 2018 - Advanced West African gold developer, Cardinal Resources Limited (ASX/TSX: CDV) (Cardinal or the Company - http://www.commodity-tv.net/c/search_adv/?v=298369) is pleased to announce that first drilling results following the recent wet season have commenced strongly, hitting further high-grade and shallow gold mineralisation at the new Ndongo East discovery reported in mid-2018. Importantly, the Ndongo Prospecting License is located only ~24 km north of the Companys Namdini Gold Project for which Cardinal declared a Maiden Probable Ore Reserve of 4.76Moz on the 18th of September 2018 (Figure 1).
On 16 July and 29 August 2018, Cardinal reported several intersections of high-grade gold at its new Ndongo East discovery within the Ndongo Prospecting License and has now intersected further high-grade gold in recently completed diamond drilling of this exciting high-grade gold target. Drilling has recently re-commenced following the wet season and is planned to steadily ramp up as ground conditions improve and current drilling results are interpreted. Currently, Cardinal has one diamond rig continuing to evaluate Ndongo East. Best intercepts in the two new holes reported today include:
- 3m (at) 29.3 g/t Au from 45m in NDDD036
- 3m (at) 4.1 g/t Au from 122m in NDDD037
Cardinals Chief Executive Officer / Managing Director, Archie Koimtsidis commented:
The Ndongo East discovery is particularly encouraging with the initial 450m strike length of strong, shallow gold mineralisation still open along strike and at depth (Figure 3).
Beyond this initial mineralised zone, a further 750m of gold mineralisation has been intersected along strike, which currently extends overall gold mineralisation of the Ndongo East discovery to approximately 1.2km (Figure 2).
We are increasingly encouraged at how Ndongo East is evolving, with the potential to add further high-grade gold ounces to our Maiden Probable Ore Reserve of 4.76Moz within the Namdini Gold Project located 24km to the south.
The Ndongo East prospect lies within a larger target area of approximately 7km in length that has yet to be drill tested. We have now recommenced drilling after the 2018 wet season with further results pending.

Figure 3: Ndongo East Prospect Section B-B¹
Ndongo Prospecting License
The Ndongo Prospecting License covers an area of 295 km2 and is considered highly prospective for the discovery of economic gold mineralisation associated with the prolific Nangodi Shear Zone, a splay fault off the main regional-scale Bole-Bolgatanga Shear. Elsewhere, the Nangodi Shear Zone is spatially related to no fewer than four gold discoveries, including the Companys Namdini Gold Project with a 4.76Moz Probable Reserve, the Shaanxi Gold Mine, the historic Nangodi Gold Mine and the 2.1 Moz Youga Gold Mine in Burkina Faso, adjacent to the Ghanaian border. In addition, there are numerous historic shallow artisanal workings along many parts of this shear zone ~15 to 20 km north of the Namdini Gold Project (Figure 1).
Ndongo East Prospect
The Ndongo East Prospect is located within NE-SW trending Birimian metavolcanics and metasediments. Gold mineralisation is developed mostly along diorite-granodiorite contact zones where competency contrasts create brittle fracturing allowing the ingress and precipitation of gold mineralising fluids (Figures 2 and 3). The mineralised horizons contain variable chlorite-silica-carbonate-sericite alteration with sulphides (mainly pyrite with very minor arsenopyrite).
Previously announced drilling intersected higher-grade mineralised structures concentrated in the northern portion of the shear zone, over a 450m strike length with coincident gold-in-soil and geophysical targets. Subsequent RC drilling along fence lines further to the southwest along strike and at depth to test for mineralisation has proven encouraging with further high-grade intercepts within the mineralised structures. This indicates that the mineralised system is open along a NE-SW strike and at depth with multiple mineralised intersections. The furthest drill fence to the southwest intersected 2m at 27.0 g/t Au from 10m downhole in NDRC247 which suggests a strike potential up to 1.2km of mineralised structures. (refer to Cardinals ASX/TSX Press Release 29 August 2018 Cardinal Extends Ndongo East Discovery Strike Length).
Additional diamond drilling is continuing at Ndongo East to test the strike and depth extents of the mineralised system and to evaluate the structural components of the various lithological units.
Drill holes for this release are detailed in Schedule 1, Tables 1 and 2 below.
