Cardinal Resources Ltd. 133m Gold Intersection within Diamond Drill Hole

03.12.2015  |  ABN Newswire
Perth, Dec 3, 2015 - Cardinal Resources Limited (ASX:CDV) ("Cardinal" or "the Company") is pleased to announce excellent results of the first two deep diamond drill holes completed on the Namdini Project ("Namdini").


HIGHLIGHTS

- Two diamond drill holes completed at Namdini Project

- 215m wide gold mineralised zone

- Significant intersections include:

- 133.75m @ 1.61 g/t from 3m vertical depth

- 87m @ 1.08 g/t from 28m vertical depth

Commenting on today's results, Managing Director Archie Koimtsidis said: "These two deeper gold mineralised intersections confirm and extend the wide and shallow mineralised intersections previously encountered from RC drilling within the Namdini Project.

"The diamond drill holes also confirm that the gold mineralisation occurs within the hydrothermally altered volcaniclastics and monzonite granitoids, which were previously identified in the RC drilling (Figures 4 to 6 in link below).

"These new results clearly demonstrate the significant depth potential of the wide gold mineralisation previously encountered at the Namdini Project".


Mineralised Zone

The wide mineralised zone at the Namdini Project occurs within hydrothermally altered volcaniclastics and monzonite granitoids. The mineralised widths range between 215m to 128m (Figures 4 to 6 in link below).

The RC drill holes drilled either side of each diamond drill hole show consistent lithologies and compare favourably with the two diamond drill holes (Figure 3 in link below). The volcaniclastics and granitoids intersected in the four RC and two diamond drill holes all contained gold mineralisation.


Diamond Drill Holes NMDD462-754 and NMRD460-774

Drill hole NMDD462-754 was cored from surface. The soft near surface material was drilled with a Triple Tube core barrel to reduce core losses. Once harder rock was encountered, then HW steel casing was inserted for stability of the hole and HQ size core was drilled to 362.5m.

Drill hole NMRD460-774 was RC drilled to 84m where water was encountered. The drill hole was cased then HQ core was drilled to 262.68m.

The drill rigs were aligned at -65deg dip drilling east which allows for the shallowing of the drill holes with depth. The azimuth was set at 095deg instead of 100deg (normal to the strike of the formations) as the borehole trace usually deflects to the right with depth due to the clockwise rotation of the drill rods.

Drill hole NMDD462-754 was surveyed near the top of the drill hole, then every 30m down the hole to determine the dip and azimuth of the drill hole with depth. Drill hole NMRD460-774 was surveyed at the end of the RC drilling to determine the dip of the drill hole.

The core from both drill holes was orientated in each drill run using a digital instrument. The core was marked showing the base of the drill hole, then the core from each drill run was laid in a length of angle iron to fit the core together so that the orientation line could be drawn along the length of the core. Geotechnical parameters were measured using this orientation line as the datum line.

The core was photographed then cut in half; one half was consistently sampled, with the remaining half stored in metal core trays and placed on metal racks under cover in the core shed at Bolgatanga. The half core samples were sent to SGS Laboratories in Burkina Faso for fire assay.


Namdini Geology

The Namdini Project is located within a Paleo-Proterozoic Greenstone Belt comprising Birimian metavolcanics, volcaniclastics and metasediments located in close proximity to a major 30 km ~N-S regional shear zone with splays (Figure 1). These rock units are intruded by felsic monzonite granitoids and quartz diorites.

The gold mineralisation is developed within foliated, sheared and highly altered rocks containing sulphides (pyrite and arsenopyrite). The host rocks dip approximately 60deg W and strike 010deg. Hydrothermal alteration is comprised of silica, iron carbonate (ankerite), sericite, epidote and chlorite. The highly altered rocks contain disseminated gold-bearing sulphides and are distinguished from the grey, unaltered, unmineralised host rocks by characteristic pale to medium green colours.

The monzonite granitoid intrusive is considered to have been the "heat engine" which remobilised gold bearing sulphide rich fluids which altered the host rocks and precipitated the gold mineralisation within them.

The NNE-SSW trending corridor containing the gold mineralisation is bounded on both east and west sides by foliated metasediments of varying compositions, also dipping 60degW and striking 010deg.

The unaltered quartz diorites contain primary pyrite sulphides and are mostly unmineralised.


Monitoring Of Drilling Programs

Cardinal's technical and management team evaluates all of the available data on a daily basis with the main focus being the expansion of the gold potential for the expanded licence areas.

Cardinal is the owner and operator of its own drill rig and has established an express assaying service with its drilling results, enabling the Company to continuously improve its drill plan strategy as new information becomes available.

The Company will continue drilling selective holes, submitting the samples and be on standby as results are received. Once the results have been assessed, Cardinal can plan further drill holes to maximise expansion of the gold inventory within the Namdini Project.
