- Twenty-four reconnaissance stream sediment samples contain gold grains.
- Additional sediment exposures in 508 m of follow up trenching/stripping.
- Specimen Area target structure traced approximately 50 m .
VANCOUVER , Aug. 8, 2018 /CNW/ – NxGold Ltd. (“NxGold” or the “Company“), (TSXV: NXN) is pleased to provide an update on its 2018 exploration program at the Mt. Roe Project located in the Pilbara region of Western Australia . The Company has recently completed a reconnaissance stream sediment sampling program to identify (i) auriferous sections of the inferred paleo-placer target horizon; and (ii) areas that have the potential to host lode gold style mineralisation. A preliminary follow-up trenching/stripping program was also completed expanding the exposure of sediments at the target horizon and continuing to evaluate the target horizon to the southwest.
Christopher McFadden , Chief Executive Officer, commented: “Our systematic approach to evaluating the Mt. Roe properties continues to support gold being shed from the Mt. Sholl ridge. The stream silt samples define key portions of the ridge with the potential to host gold mineralisation. The identification of vein structures in the ‘Specimen Area’, among others, supports the potential existence of primary gold mineralisation on the property. Both of these targets are being evaluated and we look forward to continuing to unlock the potential of this prospective project.”
Stream sediment samples
A total of 45 stream sediment samples were collected which included 5 control samples (field duplicates or quartz sand blanks). At each sample site, approximately 10 kilograms (‘kg’) of – 80 mesh (-1.77 millimetre (‘mm’)) material was sieved on site (fine fraction); a 1.5-2.0 kg subsample of this fine fraction was collected in a separate sample bag for gold and multi-element analyses. The remaining fine fraction material was processed through a sluice box with the resulting fines panned for the qualitative detection of heavy minerals. Hackly textured or pristine gold grains are interpreted to be indicative for the potential for lode style mineralisation weathering into the drainage basin hosting the sample site. Rounded or modified grains are interpreted to be either (i) derived from the inferred paleo-placer horizon; or (ii) grains more distal from a lode style mineralisation source. Assay results of the subsamples are pending.
Figure 1 shows the distribution of those samples which returned visible gold grains with an inset showing an example of gold grains recovered from a sluiced then panned stream sediment sample (grid scale dark lines 1.0 cm, light lines 2 mm).
Sixteen trenches and trench extensions totalling 508 m in length were used to further expose the conglomerate/pebbly sandstone/sandstone target horizon, to step along strike and expose the target horizon, and to further expose potential high-grade structures. The target horizon is shown in Figure 1. The trenching/stripping evaluates a strike length of approximately 2.0 km of the targeted contact of interest. Of these, seven trenches ( 150 m ) were focused on exposing and tracing the known sedimentary exposures in the Conglomerate Area, five trenches ( 206 m ) were used to trace the target horizon to the southeast and four trenches ( 152 m ) were used to further evaluate potential gold bearing structures in the “Specimen” Area.
Conglomerate Area: Conglomerate/pebbly sandstone/sandstone rocks inferred to be the source of ‘melon seed’ nuggets have been exposed by a series of trenches and stripping covering a total area of 420 m squared in two locations approximately 150 m apart. These exposures are currently being considered for larger scale sampling that would be required to better determine gold grade in a prospect that contains coarse or nugget gold.
Specimen target area: Three trenches were cut to perpendicularly cross the mineralised structure identified in the previous trenching program (see News Release dated: June 28, 2018 ); additional structures were exposed in these short trenches ( 35 m ). A long trench was excavated to cross numerous zones of float quartz in the immediate vicinity of the Specimen area. Vertical and horizontal one metre chip samples were collected from these trenches in addition to selective samples collected from the veins. A total of 29 samples were collected including four control samples (certified reference material or duplicate). These samples were sent for gold and multi-element analysis. Results are pending.
