FOR IMMEDIATE RELEASE
Aton reports the final Rodruin P hase 1 RC drilling results,
including 70m @ 1.16 g/t Au from 11m depth, and 11m @
5.01 g/t Au and 2.27% Zn in primary sulphide mineralisation
Vancouver, January 29, 2019: Aton Resources Inc. (AAN: TSX -V) (“Aton” or the “Company") is pleased to
update investors on the assay results from the final 14 holes of the Phase 1 reverse circulation percussion
(“RC”) drilling programme at its advanced Rodruin prospect, within the Company’s 100% owned Abu Marawat
Concession (“Abu Marawat” or the “Concession”), located in the Eastern Desert of Egypt.
Highlights:
• Assay results have now been received from the final 14 drill holes of the Rodruin Phase 1 RC drilling
programme, ROP-037 to ROP-050 (see Figure 1), with all holes again intersecting gold mineralisation,
other than 2 shallow holes which were terminated prior to reaching the targeted mineralised zones.
Holes ROP-037 to ROP-043 all tested the GF Zone (“GFZ”); holes ROP-044 and ROP-048 to ROP-
050 were drilled to the northeast of Aladdin’s Hill ; and holes ROP-045 to ROP-047 were drilled from
the Central Buttress Zone (“CBZ”) of the South Ridge;
• The final hole in the programme, ROP-050 at Aladdin’s Hill NE hit a zone of deeper sulphide-hosted,
gold-polymetallic mineralisation from 111m depth, returning a wide mineralised intersection of 61m @
1.55 g/t Au, 8.9 g/t Ag and 0.86% Zn, which included a high grade interval that assayed 11m @ 5.01
g/t Au, 25.8 g/t Ag, 0.20% Cu and 2.27% Zn from 158m depth;
• Hole ROP -048 at Aladdin’s Hill NE intersected the surface zone of Au and high grade Zn oxide
mineralisation, previously intersected in hole ROP -017 and in surface channel sample profile ROC-
009 (see news release dated November 12, 2018), returning a mineralised interval of 30m @ 1.33 g/t
Au, 6.5 g/t Ag, 0.28% Cu and 4.58% Zn from surface;
• Hole ROP-047 at the CBZ returned a wide near-surface mineralised intersection of 70m @ 1.16 g/t
Au and 8.3 g/t Ag from 11m depth, but had to be terminated in continuing mineralisation, due to the
unstable hole collapsing at 81m;
• All drillholes at the GFZ intersected mineralisation immediately from surface, confirming the presence
of a block of surface gold mi neralisation at the GFZ, hosted in the mapped outcropping gossan, and
which appears to extend northwards into the Central Valley. Intersections included 29m @ 1.59 g/t
Au (hole ROP-037) and 40m @ 0.74 g/t Au (hole ROP-039), both from surface;
• The Phase 1 RC programme at Rodruin has successfully identified widespread gold ( ±silver-zinc)
mineralisation over the extent of the South Ridge, including significant thicknesses of easily mineable
oxides outcropping from surface, as well as a wide zone of deeper sulphide mineralisation, believed
to be the primary equivalent of the near -surface oxide mineralisation, which is completely open in all
directions. Drilling has confirmed that high grade zones are locally present within both the near-surface
oxide and the primary sulphide mineralisation.
“We continue to be very pleased with t hese excellent results , which are consistent with what we have been
seeing, which is the potential for a large bulk mine able deposit that has a large area of m ineralisation, with
good grades and high grade shoots interspersed within it” said Mark Campbell, President and CEO. “We are
planning an aggressive exploration programme for 2019, and given the recently confirmed extension to our
exploration licenc e at Abu Marawat we pl an to undertake a substantial amount of work this year . We will
continue to drill at Rodruin throughout 2019, as well as at some of our other primary exploration targets we
have worked up within the last couple of years, to further develop the potential of our licence area and to build
shareholder value into our exploration portfolio.”

RC drilling at Rodruin
Assay results from the final 14 drill holes, ROP -037 to ROP -050, of the Phase 1 RC drilling programme at
Rodruin are now available, see Table 1 for hole collar details. Full details of the mineralised intervals from
these holes are provided in Appendix A. Holes ROP -037 to ROP-042 were all drilled to test the GFZ, some
500m southeast of the high grade mineralisation at Aladdin’s Hill (36m @ 12.47 g/t Au, see news release dated
October 1, 2018); hole ROP-043 was drilled to the northeast from the Central Valley (“CVZ”); holes ROP -044
and ROP-048 to ROP-050 were drilled to the northeast of Aladdin’s Hill to test for both near surface and deeper
sulphide mineralisation; and holes ROP-045 to ROP-047 were drilled on the CBZ (see Figure 1).
Aladdin’s Hill NE
4 holes were completed northeast of the main ancient underground workings at Aladdin’s Hill (see Figures 1
and 2). 2 shallow vertical holes, ROP-044 and ROP-048 were completed primarily to test the surface zone of
Au and high grade Zn oxide mineralisation identified in hole ROP-017 (34m @ 1.39 g/t Au and 8.86% Zn from
surface, see news release dated November 12, 2018) and in surface channel sample profile ROC-009 (65.3m
@ 2.84 g/t Au and 5.26% Zn, see new release dated September 24, 2018). Holes ROP-049 and ROP -050
were drilled on a southerly azimuth to test for both near-surface and deeper sulphide mineralisation.
Figure 2: Schematic geological plan of the Aladdin’s Hill area, showing the location of drill access
roads and pads, and drill holes ROP-044 and ROP-048 to ROP-050
Hole ROP-048 intersected the surface Au- Zn oxide zone returning intercepts of 30m @ 1.33 g/t Au, 6.5 g/t
Ag, 0.28% Cu and 4.58% Zn (at a 1% Zn cutoff grade), and 17m @ 2.21 g/t Au, 6.8 g/t Ag, 0.43% Cu and
5.98% Zn (at a 0.3 g/t Au cutoff grade) from surface. This polymetallic mineralisation occurs in strongly oxidised
and gossanous carbonate rocks, and extends the surface zone intersected in hole ROP-017 (34m @ 1.39 g/t
Au, 8.6 g/t Ag, 0.59% Cu and 8.86% Zn, see new release dated November 12, 2018). Hole ROP-044 passed
directly into unmineralised metasediments from surface, failing to intersect any mineralisation, and was
terminated at 35m. The absence of near-surface mineralisation in ROP -044 was due to structural offsets in
the immediate vicinity of the drill collar location. Hole ROP-048 also intersected lower grade Au mineralisation
hosted in carbonates below the near -surface Au- Zn zone (see Appendix A), and was terminated in
unmineralised metasediments at 65m depth.
Hole ROP-049 intersected lower grade mineralisation in weathered carbonates from surface (25m @ 0.47 g/t
and 0.66% Zn), as well as a narrow zone of contact-hosted mineralisation (3m @ 5.71 g/t Au, from 37m).
Hole ROP-050 also intersected this zone of low grade near-surface mineralisation in weathered carbonates
(16m @ 0.48 g/t and 0.98% Zn, from 9m). It also and most significantly intersected a wide zone of sulphide
mineralisation at depth ( 61m @ 1.55 g/t Au, 8.9 g/t Ag and 0.86% Zn, from 11m ), including a high grade
interval of 11m @ 5.01 g/t Au, 25.8 g/t Ag, 0.20% Cu and 2.27% Zn , from 158m . This interval of sulphide
mineralisation is very significant in that it extends the sulphide mineralisation intersected in hole ROP -017
(55m @ 1.23 g/t Au, 10.4 g/t Ag, and 1.40% Zn, see new release dated November 12, 2018).
Central Buttress Zone

location of drill access roads and pads, and drill holes ROP-043 and ROP-045 to ROP-047
A further 3 holes ROP-045 to ROP-047 were collared on a second drill pad on the CBZ, on the northern flank
of the South Ridge (see Figures 1 and 3). 2 angled holes were drilled towards the east and south, as well as
a single vertical hole. Drilling of the CBZ from above this pad previously returned good intersections including
40m @ 1.30 g/t Au and 13.5 g/t Ag from surface, and 11m @ 5.20 g/t Au and 23.0 g/t Ag from 59m (ROP -
032), 31m @ 2.45 g/t Au and 12.5 g/t Ag from 2m depth (hole ROP-034) and 34m @ 2.00 g/t Au from 10m
(hole ROP-033, see news release dated January 3, 2019).
All 3 holes hit gold mineralisation with hole ROP -047, drilled towards the east, returning a wide mineralised
intersection of 70m @ 1.16 g/t Au and 8.3 g/t Ag from 11m depth, in weathered and sometimes gossanous
carbonates. This hole unfortunately had to be prematurely terminated in mineralisation due to the hole
collapsing in unstable ground from about 50m downhole depth onwards.
Hole ROP-045, drilled towards the south, intersected 18m @ 1.74 g/t Au, 9.2 g/t Ag and 1.08% Zn from 17m
depth as well as a lower interval of 11m @ 0.96 g/t Au and 9.1 g/t Ag from 52m, also in weathered and
sometimes gossanous carbonates. Ancient underground workings were intersected i n this hole between 25-
28m, with no sample recovery . Zero grade was assigned to the mined interval, thus clearly underestimating
the pre-mining grade of the overall mineralised intersection.
Vertical hole ROP -046 intersected 33m @ 0.92g/t Au and 7.1 g/t Ag from 32m depth, after passing from
unmineralised metasediments into weathered and gossanous carbonates.

GF Zone
The GFZ is located approximately 500m east-southeast of the main workings at Aladdin’s Hill, and is expressed
at surface as a series of dark chocolate brown gossanous carbonates, again with abundant ancient workings.
6 holes ROP-037 to ROP-042 were completed from 2 drill pads at the GFZ (see Figures 1 and 4), with one
additional hole, ROP-043, drilled under the North Ridge from the Central Valley (see Figures 1 and 3), testing
a possible strike continuation of the GFZ.
3 holes were completed from the upper, southernmost pad at the GFZ, holes ROP -037 to ROP-039, of which
ROP-037 was a re- drill of hole ROP -036 (see news release dated January 3, 2019). All 3 holes intersected
good thicknesses of gossanous carbonate hosted mineralisation from surface, returning mineralised intervals
of 29m @ 1.59 g/t Au (composite intersection from holes ROP -036 and ROP-037, see Appendix A), 35m @
0.64 g/t Au (hole ROP-038) and 40m @ 0.74 g/t Au (hole ROP-039).
A further 3 holes were drilled from a lower pad. Hole ROP -041 was abandoned after intersecting ancient
workings very near to surface and was not sampled. All 3 holes again intersected gossan-hosted mineralisation
from surface, returning mineralised intervals of 29m @ 0.74 g/t Au (hole ROP -040), and 35m @ 0.83 g/t Au
(hole ROP-042).
Hole ROP-043 was drilled from the Central Valley about 150m to the north and returned a mineralised interval
of 25m @ 0.73 g/t Au from 3m depth, in weathered carbonates, beneath ancient workings. It appears likely
that the mineralisation intersected in this hole represents a northerly extension of the GFZ.
Discussion
The final batch drilling of results from the Phase 1 RC programme at Rodruin has again continued to confirm
the presence of outcropping gold mineralisation in weathered and gossanous carbonates at surface or very
near to surface over a wide area of the South Ridge at Rodruin, as well as indicating the presence of primary
sulphide mineralisation at depth. Once again gold mineralisation was returned from all holes that reached their
planned targets.
Aton is particularly encouraged by the deeper gold- polymetallic mineralisation hosted within altered dolomitic
carbonate rocks intersected in hole ROP -050. This intersection expands the zone of sulphide mineralisati on
previously identified in hole ROP-017. This mineralisation strongly appears to be the primary equivalent of the
gossan-hosted mineralisation seen over large extents of the South Ridge. The identification of a deep primary
equivalent of the widespread surface mineralisation provides strong support to the Company’s interpretation
that Rodruin has the potential to host a large gold deposit.
It is also noted that the deep sulphide mineralisation in hole ROP -050 is effectively blind, occurring beneath
completely unmineralised metasediments (greywackes, slates), and is open in all directions. Th is sulphide
gold-polymetallic mineralisation is located vertically beneath holes ROP -044 and ROP -048 which were
terminated in the barren metasediments and not drilled deep enough to intersect t he sulphide mineralisation.
Hole ROP -049 was also terminated prematurely in barren metasediments, and re- interpretation of this
structurally complex zone, which is affected by faulting, low angle thrusting, and folding is being undertaken.
It will probably be necessary to deepen some of these holes during the upcoming Phase 2 drilling programme,
and expanding the sulphide mineralisation zone will be a major focus in Phase 2.
Hole ROP-048 also expanded the surface zone of gold and high grade zinc oxide mineralisation previously
identified in hole ROP-017 and in surface channel sample profile ROC-009 (see news release dated November
12, 2018), and further delineation of this zone will also be a focus of the Phase 2 RC programme, notably to
the southeast of hole ROP-048 where outcrop is totally obscured by cover (see Figure 2). It is also noted that
this zone bears similarities to a zone of similar gold and high grade zinc oxide surface mineralisation at
Hamama East (see news release dated May 3, 2018).
Holes ROP-045 to ROP-047 confirmed the presence of significant further widths of near surface mineralisation
at the CBZ, previously drill ed in holes ROP-031 to ROP-034 (see news release dated January 3, 2019) . The
intersection of 70m @ 1.16 g/t Au from only 11m depth in hole ROP -047 is particularly encouraging in that it
confirms a broad zone of continuous mineralisation effectively outcropping from surface at the CBZ , and is
additive to similar broad zones of mineralisation identified from surface in holes ROP-031 to ROP-034.
Drilling at the GFZ was also most encouraging with consistent gold mineralisation being identified from surface,
albeit it a lower grade than from other zones . This surface mineralisation identified at the CBZ and the GFZ,
as well as that previously identified in the Aladdin’s Hill and Spiral Pit (“SPZ”) areas would be readily amenable
to open pit mining and extraction at potentially very low stripping ratios.
Aton is very pleased with the results from the Phase 1 RC drilling programme at Rodruin in that the drilling has
achieved its primary objective of confirming the presence of gold mineralised zones outcropping at surface
over a significant extent of the South Ridge, and their primary equivalent at depth. The drilling has continued
to confirm the structural complexity of the area; that the gold mineralisation is largely, but not exclusively,
hosted within altered, dolomitic and apparently sedimentary carbonates, occurring within a metasedimentary
package; and that the mineralisation is typically strongly oxidised to gossans in the near-surface environment,
and has a polymetallic assemblage with subsidiary Ag, Zn, and sometimes Cu and Pb. The bulk of the gold
mineralisation at Rodruin bears very broad similarities to that at the Company’s Hamama project, but has a
notably higher overall Au tenor, and a structurally controlled component to the mineralisation that is not typically
seen at Hamama.
Aton is also pleased that the drilling continues to confirm the Company’s early interpretation that the
mineralisation at Rodruin also includes higher grade free gold- bearing zones (see new s release dated
December 14, 2017). The high grade mineralisation at Aladdin’s Hill is associated with east -west trending
structural controls, and is hosted within a series of strongly phyllic altered rocks inter preted to be altered and
oxidised metasediments. Similar structural analogues have been interpreted at the SPZ, and possibly also on
the CBZ. While the initial results from hole ROP-003 at Aladdin’s Hill (36m @ 12.47 g/t Au from 5m, see news
release dated October 1, 2018) were exceptional, the subsequent drilling has continued to identify high grade
near-surface zones, grading in excess of 5 g/t Au at both the CBZ and the SPZ, and hole ROP -050 has now
also confirmed the presence of high grade zones in the primary sulphide mineralisation.
Aton is now making preparations for the commencement of the Phase 2 drilling programme at Rodruin. Phase
2 will continue to follow up on Phase 1, and will additionally focus on previously untested areas of the South
Ridge, such as those areas under superficial cover, as well as attempting to delineate and expand the zone of
primary mineralisation identified in holes ROP-017 and ROP-050. It is also planned that a drill access road will
be constructed around to the northern si de of the hitherto untested North Ridge , with the aim of drill testing a
zone of high grade ancient workings on quartz-sulphide veins that yielded samples assaying up to 321 g/t Au
(see news release dated February 6, 2018) , as well as zones of argillic hydrothermal alteration, associated
with Cu, Pb and Te-bearing veins.
Rodruin
The Rodruin prospect was discovered in December 2017 by Aton geologists (see news release dated
December 14, 2017), and is located approximately 18km east of the Company’s Hamama W est mineral
deposit. Field mapping and sampling has indicated the presence of ancient mine workings and extensive gold
mineralisation over an area of at least 700m x 400m at surface. Mineralisation is associated with a sequence
of carbonate and metasedimentary slate and greywacke rock types. Abundant visible gold has been identified
in hand specimens from surface outcrops, and ancient dumps and underground workings, with individual
selective grab samples assaying up to 321 g/t Au (see news releases dated February 6, 2018, March 5, 2018
and April 16, 2018). Drilling has now confirmed the presence of high grade gold mineralisation at Aladdin’s Hill
with individual samples returning assays of up to 221 g/t Au over metre intervals (see news release dated
October 1, 2018). Drilling results released to date from Rodruin include intersections of 36m @ 12.47 g/t Au
from 5m (hole ROP-003 at Aladdin’s Hill, see news release dated October 1, 2018), 163m @ 0.90 g/t Au from
surface (hole ROP-017 northeast of Aladdin’s Hill, see news release dated November 12, 2018), 20m @ 5.36
g/t Au (hole ROP-029 at the Spiral Pit, see news release dated December 10, 2018), and 40m @ 1.30 g/t Au
and 13.5 g/t Ag from surface, and 11m @ 5.20 g/t Au and 23.0 g/t Ag from 59m (hole ROP-32 at the CBZ, see
news release dated January 3, 2019).
Sampling and analytical procedures
Drill holes were drilled at 140mm diameter, and the bulk percussion chip samples were collected directly into
large plastic bags from the cyclone every metre, numbered with the hole number and hole depths by the drill
crew, and laid out sequentially at the drill site. RC chips were logged onsite by a senior Aton geologist. The
bulk 1m samples were weighed, and subsequently riffle split through a 3- tier splitter onsite by Aton field staff
to produce an approximately 1/8 split, which was collected in cloth bags, numbered and tagged with the hole
number and depth. The reject material from this initial bulk split was re- bagged, labelled and tagged, and the
bulk reject samples will be stored and retained on site at Rodruin. A representative sample of each metre was
washed, stored in marked plastic chip trays, each containing 20m of samples, photographed, and retained
onsite as a permanent record of the drill hole.
All the 1m split samples were weighed again, and the samples selected for assay were riffle split onsite,
typically a further 3- 4 times using a smaller lab splitter, to produce a nominal c. 250-500g sample split for
dispatch to the assay laboratory. The laboratory splits were allocated new sample numbers. QAQC samples
were inserted into the sample runs dispatched to the assay laboratory at a nominal rate of 1 duplicate sample
for every 10 drill samples, 1 blank sample every 10 samples, and 1 standard sample of a certified reference
material every 40 samples. Reject material from the 1m samples , after the laboratory split had been taken,
and any unused 1m splits will be retained at the Company’s Hamama facility for future reference purposes, as
and when required.
The selected c. 250-500g drill and channel samples were shipped to ALS Minerals at Rosia Montana, Romania
for analysis. Samples were analysed for gold by fire assay with an atomic absorption spectroscopy (“AAS”)
finish (analytical code Au- AA23); and silver, copper and zinc with an aqua regia digest followed by an AAS
finish (analytical code AA45). High grade gold samples (>10 g/t Au) were re- analysed using analytical code
Au-AA25 (also fire assay with an AAS finish). High grade Ag and base met al samples (Ag >100 g/t, and Cu
and Zn >10,000ppm or >1%) were re-analysed using the ore grade technique AA46 (also an aqua regia digest
followed by an AAS finish).
