VANCOUVER, July 17, 2019 /CNW/ - 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."
Prinsep Targets
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.
Sholl Targets
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 115m
anomalous 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.

verified by the QP.
Sampling from 2019 mentioned in this news release has the
following parameters: silt samples are selective sample sites
within drainages where material was collected and sieved to -2mm at
the sample site until a 2kg-3kg sample was collected which was
placed in a labelled sample bag and then sealed; soil samples were
collected at predetermined coordinates found by handheld gps units
(80m x 40m or 40m x
20m spacing) where surficial material
was moved aside, a hole was dug to the B or B/C horizon, material
was sieved to -2mm until a sample of 2kg was collected and placed
in a labelled sample bag, the hole was backfilled and then
re-covered with the surficial material; rock samples are selective
grab samples from outcropping material placed in labelled sample
bags; chip samples are 0.5m to
1m long samples collected on the
walls or floors of a trench by way of chipping along the sample
line with a hammer capturing the sample material on a plastic sheet
and transferring to a sample bag or captured directly in a sample
bag. Analysis of the samples was undertaken at Intertek Genalysis
of Perth Australia using the
following methods: silts CN500/MS, soils AR10/OE32, rocks and chips
AR10/OE32 with AR10/eMS for gold. Overlimits analysis methods for
base metals was 4AH/OE and for gold was FA25/OE.
