Aben Resources holds a 100% interest in the 7,400-hectare Justin Gold Project. The property is located in the southeast Yukon on the Tintina Gold Belt to the immediate southeast of Golden Predator's 3 Aces project. The Justin Project is approximately 35 kilometres southeast of the Cantung Mine and has an all season road running through the claims.
2017 - 2019 Exploration at Lost Ace Zone
Work completed on the Justin Gold Project in 2018 included the collection of 19 channel and 28 chip samples from 5 trenches, 16 rock samples, 7 till samples and 240 soil samples with coverage totaling 6.0 line-km. The 2018 field program focused primarily on the Lost Ace Zone, an orogenic-style quartz-gold bearing zone previously discovered in 2017.

Channel sampling in 2017 at Lost Ace returned 1.44 g/t Au over 5 metres including 4.77 g/t Au over 1 metre in addition to a bulk soil sample that contained 1135 visible gold grains, the majority of which were termed ‘pristine’ indicating a proximal bedrock source for the gold. Lost Ace is an exciting new prospect on the Justin Property as it is located within 2 km of Aben's mineralized POW Zone and bears striking similarities to Golden Predators adjacent 3 Aces project.

Justin Project, Yukon Lost Ace Zone Presentation
2019 exploration at the Justin Gold Project will include drilling, prospecting, geologic mapping and surface sampling across the highly prospective property. The first phase is anticipated to begin in early June with mobilization of a track mounted Rotary Air Blast (RAB) drill to the recently discovered Lost Ace Zone, where 2018 trenching returned values ranging from trace to 20.8 g/t gold over 4.4 meters including 88.2 g/t gold (Au) over 1.0 m. The Lost Ace Zone is located 2 kilometers west of the POW Zone, which was discovered in 2010. The RAB drill is a cost-effective tool to quickly evaluate the high-grade near surface gold-bearing mineralization present at Lost Ace, interpreted to be orogenic-style quartz-gold veins that bear a strong resemblance to and share a similar geologic setting with Golden Predator’s adjacent 3 Aces Property. Geologic evidence and observations at Lost Ace point toward the existence of a multi-phase hydrothermal system with the potential for overprinting mineralizing systems with the POW Zone.
Concurrent with the RAB drilling at Lost Ace, Aben will conduct diamond drilling at the POW Zone where drilling in 2011 and 2012 successfully discovered intrusion-related gold mineralization with intercepts reported ranging from trace values to highs of 1.19 g/t Au over 60.0 m (including 2.47 g/t Au over 21.0 m) and 1.49 g/t Au over 46.4 m. The POW Zone will be further evaluated as a potential host for bulk-tonnage gold mineralization and to test for the continuity of higher-grade skarn mineralization along strike. In addition to drill testing both of these exciting targets, several other high-priority exploration targets that have seen limited work but have yielded encouraging results will receive field evaluation and surface sampling.
Past Exploration at Justin Gold Project
In 2011, a Phase I 2,020 metre diamond drill program consisting of ten drill holes was completed on the Justin Property. The drill program was designed to assess the potential mineralization at the POW, Confluence, Kangas and Main zones. The drilling was the first ever completed on the POW, Confluence and Kangas zones. The 2011 activities represent the first systematic drilling campaign on the project since a small four hole program was completed on the Main zone in the mid-1980's.
During the 2011 field program, mapping of the geology in the general area of the POW Zone was carried out to follow up on anomalies from the 2010 geophysical survey. This geophysical survey highlighted a pronounced magnetic high-EM conductor zone 400 metres west of the newly discovered gold mineralization from the 2010 field work and surface sampling. A number of soil and rock samples were also collected to complement the geological mapping. This follow-up work on the POW Zone led crew members to investigate the source of the strong EM geophysical conductor outlined by the airborne survey conducted in 2010. Along the strike of a strong EM lineament, a 10m-wide zone of mineralized quartz breccia was discovered which is considered to be a favourable target for gold and silver mineralization. This resulted in the expansion of the 2011 drill program to include two additional holes designed to test the newly discovered POW Zone.
In November 2011, Aben released the first drill hole results received from the 2011 drill program in which a significant new greenfield gold discovery had been made. The Company intercepted 60.00 metres of 1.19 g/t gold including 21.0 metres of 2.47 g/t gold in hole JN11009 in the never before drilled POW Zone.
Justin Project Plan View of Pow Zone Drilling
The intercept observed in JN11009 starts at a vertical depth of 113 metres and is dominated by massive skarn-style replacement mineralization, which has been overprinted by quartz-calcite stock work veining. Both the skarn-style and vein-style mineralization carried gold values. The geochemical signature of the mineralized zone is characterized by elevated Au, Bi, Cu, Mo and W supporting an Intrusion Related Gold System (IRGS). The 2010 geophysics outline an inferred buried intrusive stock, represented by a pronounced magnetic low, which lies between the POW Zone and the Main Zone located 2.4 kilometres to the south.
A second hole, JN11010, was drilled into the POW Zone which intercepted 11.3 metres of 2.70 g/t gold and 29.00 g/t silver starting at a vertical depth of 125 metres. The mineralized intercept in drill hole JN11010 correlates with the upper zone intercepted in Hole JN11009 of 60 metres of 1.19 g/t Au. Both exploratory holes drilled into the POW Zone in 2011 intercepted significant gold mineralization and this mineralization is open in all directions.
Additional ground work at the POW Zone in 2011 returned surface samples up to 8.97 g/t Au and 84.10 g/t Ag. Positive surface sampling results from 2010 and 2011 are located 400 metres to the east of the new gold discovery in holes JN11009 and JN11010.
Aben also drill tested the Kangas Zone in 2011, located 1.4 kilometres south of the POW Zone. Three holes totaling 494.20 metres were drilled from two pads on the Kangas Zone (holes JN11001, JN11002 and JN11003). Difficult ground conditions hampered drilling efforts, and target depths were reached on only one of the three holes. A new high grade silver-copper zone was intercepted in Hole JN11003 which was the only hole to intersect significant mineralization despite being abandoned within the contact of a fault zone. A 1.07 metre interval within the contact zone of the fault returned values of 7320 g/t Ag (234 oz/ton Ag) and 3.52% Cu at a down-hole depth of 42.23 metres. Sample recovery over the interval was only 15%, and therefore results may not reflect the true thickness or tenor of the mineralization. The hole was terminated within the mineralized interval due to poor ground conditions. This newly discovered silver-copper zone is open along strike and follow-up drilling will be conducted next season to further delineate this high grade zone.
As a result of the new greenfield gold, silver and copper discoveries on the Justin Project, Aben acquired more claims around the property and in particular around the POW Zone on the northern part of the project. The Company acquired 14,274 additional acres of mineral tenure in the immediate vicinity of the project to facilitate an even more aggressive work program in the 2012 field season.
A seasonal, 20-man exploration camp was constructed adjacent to the Nahanni Range Road on the Justin property, and serviced all exploration activities in 2012. The exploration in 2012 included an aggressive diamond drill program focused on follow-up and expansion work around the newly discovered POW Zone. The field work also included additional infill geophysical and geochemical surveys as well as detailed geological mapping.
A total of 1,994 metres was drilled in nine holes during the 2012 field season with all seven drill holes that were completed to their target depths successfully intersecting gold mineralization while two holes were abandoned due to difficult ground conditions. Significant drill results from the program included 46.4 metres of 1.49 g/t gold in hole JN12011 and 88.5 metres of 0.73 g/t gold in hole JN12018. The POW Zone continues to exhibit strong continuity of mineralization and remains open in all directions. Mineralization at the zone has been traced along surface for approximately 450 metres west-east by 200 metres north-south and to 205 metres depth.
Drilling to date also confirmed the presence of a shallowly buried granitoid intrusion immediately underlying the POW Zone. Detailed mapping to the south of the POW Zone has since confirmed the presence of the intrusive body at surface. The contact zone of the intrusion with the surrounding carbonate country rocks is a primary drill target as it is an important control on the skarn-replacement mineralization observed in the first few holes at the POW Zone. The vast majority of the intrusive stock and its surrounding contact aureole at the Justin Project have yet to be tested and both remain very high priority targets for future exploration and drilling. There are also large untested geophysical anomalies proximal to the POW discovery zone, which are considered high-priority targets.
Besides skarn-hosted gold mineralization, other characteristics of IRGS deposits such as sheeted veining have been observed at the Justin Project in drilling and on surface, both within the intrusion and the surrounding country rock. Multi-phased precious metal mineralization is present at the property and displays a geochemical affinity to an Intrusion Related Gold System and indicates that the mineralizing system was long-lived.
Producing IRGS deposits within the Tintina Gold Belt include Kinross' Fort Knox operation in Alaska, with reported proven and probable reserves of 314 million tonnes grading 0.43 g/t gold, representing 4.3 million ounces of contained gold (Kinross Mineral Reserve and Resource Statement, December, 2011). Advanced IRGS projects in the Yukon include Victoria Gold's Eagle Gold Deposit which is expected to be the Yukon's next operating gold mine and includes Probable Reserves of 2.3 million ounces of gold from 92 million tonnes of ore with a grade of 0.78 g/t gold (outlined in a NI 43-101 definitive feasibility study). The NI 43-101 Compliant Mineral Resource has been estimated to host 222 million tonnes averaging 0.68 g/t gold, containing 4.9 million ounces of gold in the Indicated category, inclusive of Probable Reserves, and a further 78 million tonnes averaging 0.60 g/t gold, containing 1.5 million ounces of gold in the Inferred category (Victoria Gold website, November, 2012). Readers are cautioned that past results or discoveries on proximate land are not necessarily indicative of the results that may be achieved on the Justin property.
The property is host to numerous styles of intrusive and sediment hosted gold mineralization located within several main bulk-tonnage target areas. There are three different styles of mineralization including epithermal, skarn and sediment-hosted gold mineralization. The variety of mineralization styles makes the property an excellent candidate for combined bulk-tonnage and high-grade gold mineralization.
The Main Gold Zone hosts gold-bearing pyritic mineralization which occurs within a quartz monzonite dyke and adjacent calcareous siltstone. Historic chip sampling across this zone returned an average grade of 2.38 g/t Au over 22.5 metres. The Main Zone remains open to the east and along strike to the north into overburden-covered areas. The Confluence Gold Zone consists of a 600 metre by 250 metre area of coarse clastics hosting considerable fracture controlled chalcedonic veining. Historic grab samples from the zone returned gold values as high as 59.25 g/t Au in addition to historic chip sampling averaging 4.24 g/t Au over 4.5 metres.
The Kangas Gold Zone consists of a 75 metre by 400 metre zone of skarn and replacement style mineralization within calcareous siltstone, which has returned widespread anomalous values of up to 3.46 g/t gold. The POW Zone, discovered by Eagle Plains during an exploration program in 2010, consists of a calc-silicate skarn system as well as chalcedonic and quartz veining with arsenopyrite and pyrhhotite in coarse clastic sediments.
The Justin property has the potential to host both high-grade and bulk-tonnage gold mineralization and many targets on the property remain to be tested.
The regional geology of the southeast Yukon is represented by the basement rocks of the Selwyn Basin, Late Precambrian to Early Cambrian Hyland Group sediments. Regional mineralization is generally controlled by Mid-Cretaceous Tombstone Suite quartz monzonite intrusive stocks. The Justin Property is underlain by sedimentary rocks assigned to the Yusezyu Formation. The three distinct styles of mineralization on the property are thought to be a direct reflection of a long lived, widespread mineralizing event occurring in reactive calcareous sediments.
The POW Zone geology is characterized by interbedded sequences of west-southwest striking, moderately north-northwest dipping fine to coarse grained siliciastics and calc-silicate altered limestones of the Hyland Group. The northern margin of the POW Zone is bound by the March Creek Fault, a regional structure interpreted as a deep seated strike-slip thrust fault. The fault is observed on the property and separates the Proterozoic-Cambrian Hyland Group from the Cambrian-Ordivican Rabbitkettle Formation. The southern extent of the POW Zone is underlain by a granodiorite stock and quartz monzonite dikes, interpreted to be part of the Cretaceous Tombstone-Tungsten Suite. The newly discovered POW Zone lies within the contact aureole of the granodiorite stock and is cross cut by at least three northerly trending quartz-monzonite dikes measuring 10.0 - 25.0 metres in thickness. Mineralization within the zone is observed as massive skarn-style replacement of limestone beds and quartz-calcite stock work veining. The mineralization style and spatial association to intrusive rocks is similar to that observed at the Main Zone.
