NxGold Ltd. (“NxGold” or the “Company”), (TSXV:NXN) is pleased to announce the results of the Q1/Q2 2019 field program at the Mt Roe Gold Project located south of Karratha in Western Australia. The program focussed on further defining a number of target areas and continued evaluation of coarse gold on surface near the inferred conglomerate gold geological time horizon. The Mt. Roe Gold Project is comprised of two groupings of tenements being the Prinsep and Sholl tenements. The results are presented below on a target area by target area basis.

Christopher McFadden, Chief Executive Officer, commented, “Through a process of patient and systematic exploration steps our team has advanced a number of target areas at the Pilbara project. In addition, although lower priority at this time we continue to uncover sufficient conglomerate gold style nuggets to keep that exploration model available as a viable option as our neighbours continue to evaluate the economic viability of that deposit type.”
The Prinsep South target area identified in 2018 by grab samples of outcrops in areas identified by a limited soil sampling program was subject to a more comprehensive gridded soil survey collecting 179 soil samples (including QA/QC samples). This work defined a core anomaly 200 metres (‘m’) by 75 m defined by the >98th percentile gold values (67parts per billion (‘ppb’) to 248ppb) within a broader anomalous halo (>80th percentile; >16ppb gold) with dimension of 600 m by 100 m. The anomaly is open to the South and West. Rock samples from exposed outcrops in the area within the anomaly returned a range of gold values (detection limit to 9.7 g/t gold). Two other minor anomalies are apparent as well; one (20m x 315m) that appears to be associated with a late NW structure cutting across stratigraphy and the other (30m x 115m) associated with hematite altered cherts and iron formation. Mapping indicates this area is a strongly deformed sedimentary rock sequence structurally juxtaposed against a talc schist (ultramafic rock unit) adjacent to the regional Sholl Shear Zone structural corridor (Figure 1).
No work was completed on the historical Lulu target area. The Lulu target was historically defined by limited soil sampling. Percussion drilling from the 1970’s did not analyse for gold however the chip logs indicate a wide structurally controlled section of sericite schist hosting numerous quartz veins that returned low level anomalies of lead, zinc and silver.
Regional evaluation silt samples were collected (19 samples) across the recently granted tenements with only one result of interest, 167 ppb gold, from a drainage west-northwest of the Hawk/80oz target area (Figure 2).
The 2018 80m x 40m soil grid at the Eagle target area was expanded to the northeast and southwest to include the Kangaroo and Bulldog target areas respectively comprising of 72 samples. A limited, two-point gold in soil anomaly located on an inferred ENE trending structure and at the edge of a magnetic anomaly (see News Release 26 November 2018) occurs in the Kangaroo area but does not appear to be continuous to the Eagle area. The Bulldog area hosts a 300m x 100m gold in soil anomaly (>90th percentile gold values; >11ppb) that appears to be defined by a structure hosting a ‘breccia dike’ where it crosses inferred moderately magnetic mafic schist (undifferentiated basalts). This unit is also associated with a roughly ovoid shaped 300m x 175m, >90th percentile gold in soil anomaly that is coincident with a moderate to strong magnetic inversion anomaly estimated to occur approximately 150m below surface in the southern Eagle area. No additional soil sampling was undertaken in the main Eagle target area (see News Release 18 December 2018); chip samples (18 samples) from trenching returned values from detection limit to 86ppb gold. This main Eagle anomaly is hosted in calcrete with visible gold observed in narrow structures (see News Release 10 September 2018) and is underlain by a moderate to strong magnetic feature as referred to above. These areas are considered ready for drill evaluation.
Gridded soil sampling (80 samples) expanded the Hawk target area the northeast, northwest and southwest with results ranging from detection limit to 355ppb gold. The >90th percentile gold value (>25ppb Au) anomalous zone is still broadly open to the northeast with two roughly 100m wide anomalous zones converging back towards the centre of the grid; no coherent >98th percentile of gold values zone defines a clear target zone. To the northwest corner of the grid an open 150m x 60m, >98th percentile of gold values (75ppb to 355 ppb gold) appears to isolate the potential source area for coarse hackly (inferred to be proximal to source) gold collected while trenching in the 80oz patch (Figure 3a); another 150m x 80m open >80th percentile (7ppb to 75 ppb) occurs in the northern part of the grid. Given the restricted area of the potential source structure the considered next step would be drill fences across the prospective corridor. The gold nuggets are considered selective samples identified by the use of a metal detector during trenching activities.
An initial pass of wide spaced soil samples was collected at the MAG target area recognising that the area was covered with colluvium and alluvium with limited outcrop exposures. The limited sampling (12 samples) did not allow for a statistical review of the soil results however a qualitative examination appears to indicate a lack of metals response over the surface projection of the previously identified magnetic anomaly (see News Release 24 April 2019) with weak response on the edge of the projected anomaly. Additionally, on the margins of the projection, veining in weakly sheared chlorite altered gabbroic units returned silver values of interest, 194g/t and 458g/t; these samples also contained elevated copper, zinc values (0.47%, 0.17% Cu and 0.77%, 0.75% Zn respectively) and antimony (0.05% to 0.16%). A total of 11 rock samples were collected with silver values ranging from detection limit to 458 g/t. A review of historic electromagnetic surveys in the area (airborne) indicate a weak to moderate anomaly exists in the area of the magnetic feature. A proposed next step would include a ground based electromagnetic survey to determine if there are associated conductors which could indicate disseminated to semi massive sulphide bodies.
The Crow target area was initially defined in 2018 and was followed up in this program with an 80m x 40m spaced soil sample grid (61 samples). The main anomaly area was not highlighted however immediately to the east a 220m x 115manomalous copper zone (>90th percentile of copper values; >106ppm Cu) is coincident with a more restricted 100m x 50m gold anomaly (13 ppb to 73 ppb). This area will require a field check prior to undertaking any additional activity.
Limited work was completed in the Hamburger target area in order to define a structural control that could be the host for previously collected gold nuggets attached to quartz vein fragments. This work was not successful and only produced a collection of detrital gold nuggets (Figure 3b) many of which have the same shape and texture to nuggets said to be associated with conglomerate gold targets in the broader Pilbara region. Our work to date has concluded that there is limited potential for conglomerate gold, at least for a significant enough volume of material to be of interest, however the presence of these nugget types remains to be fully explained. The gold nuggets are considered selective samples identified by the use of a metal detector during trenching activities.
The Bulldog target area was covered as part of the Eagle soil grid expansion. A 400m x 70m gold in soil anomaly (6ppb to 30ppb) was defined coincident to a northerly trending structure part of which hosts the 2.6Ga ‘Breccia Dike’ where it cuts across an inferred fold closure in a variable magnetic mafic volcanic unit. This has also been an area well known of the collection of detrital gold nuggets by metal detecting. This area requires field review to determine next steps.
The Kangaroo target area was covered as part of the Eagle soil grid expansion. While 2018 silts indicate a weak to moderate anomaly (0.67ppb to 39.42ppb gold) the soil sampling only returned a single point anomaly (77ppb to >4000ppb) which was determined to be caused by a coarse piece of gold based on the high variability of the multiple analyses undertaken on this sample. While this sample is coincident with an inferred ENE tending structure no further work is contemplated at this time.
The Swan target area did not receive any additional work this program as it is considered a drill ready target.
