The Zackly area was originally explored from 1981 to 1994 by several companies. Programs included surface sampling, trenching, geophysics and both core and reverse circulation drilling totalling approximately 12,000m in approximately 85 holes. Three historical estimates (1982, 1987 and 1993) have been completed for the Zackly ‘Main Skarn’ zone, one of the three known mineralised skarn zones located along the Zackly skarn trend.
Historical conventional soil sampling over the Zackly prospect area defined multiple, large, highly anomalous Cu-Au zones currently untested by drilling. Aeromagnetic anomalies encompassing Zackly extend both northwest and southeast of the project, potentially reflecting extension of surface mineralisation.
More Recent Exploration
Since 2010, Millrock Resources Inc collected approximately 950 soil and 760 rock samples for assay and/or spectral analysis, as well as 99 stream sediment samples throughout the project area. A new EM/magnetic/radiometric survey was also conducted over the property in 2013. The work resulted in the definition of at least seven additional copper and/or gold prospects and anomalies and for the first time revealed entire region’s the large scale of mineralisation.
PolarX’s Exploration Program – Zackly Prospect
A major exploration program commenced in 2017, where PolarX re-drilled the Zackly high-grade copper-gold skarn to:
- test and upgrade the historic resource to JORC (2012) standard, and
- test for along-strike extensions of the known mineralisation.
Induced polarisation (IP) surveys were also completed at Zackly and this data is currently being used to assist in planning additional drill holes to test the eastern and western extensions of the Main Skarn. The IP images are broadly consistent with the soil anomalism, mapped geology and drilling to date and assist in planning these further resource extensions.
PolarX’s Resource delineation drilling at Zackly began at the end of August 2017. Diamond drilling evaluated potential eastern and western extensions of known mineralisation, as indicated by IP surveys.
PolarX drilled core holes to twin/infill 12 of the historical holes drilled into the deposit in 1981/82 and 1993/94. These core holes verified previous drilling results and allowed PolarX to calculate a modern more accurate revised resource estimate to JORC 2012 standard as follows:
Zackly is mineralised from surface and the mineralisation remains open along strike in both directions and at depth. Only 1,050m of its approximate 5km known trend has been drilled to date and it has only been modelled to shallow depth to date.
The Company is currently drilling 23 planned holes in 2018 to test strike and depth extensions at Zackly with a view to substantially increasing the initial resource base.
PolarX drill-core recoveries have been excellent and have provided significantly more geological data than the historic work. Importantly, it provided evidence of a significantly larger Porphyry copper/gold source below or near Zackly.

The new Zackly drill core will also provide material to use in preliminary metallurgical test work to provide commercial processing options for copper and gold.

The Mars Prospect
Is located 6.4km west of Zackly. The prospect consists of altered gabbro/dolerite intruding volcanics with lesser sedimentary rocks, locally containing gossan exposures. The altered zones commonly contain variable copper mineralisation.
Soil sampling across the prospect defined a +420 ppm copper anomalous zone measuring approximately 950m x 1.7 km. Rock samples of altered volcanic rock returned assays as high as 7.4% Cu. Anomalous gold-in-soil values are common within the area of the +420 ppm Cu anomaly, including multiple samples assaying +0.100 ppm Au. Assays as high as 1.78 ppm Au have been returned from rock samples here.
The Jupiter Prospect
Is hosted in altered volcanic rocks near a contact with dioritic intrusive rocks. The prospect, which is located approximately 1.8km north of the main Zackly skarn, is characterized by east and northerly-trending, altered, Cu/Au-bearing fracture/vein zones. Soil sampling has defined a +420 ppm copper anomaly measuring approximately 800m x 1.9km. Anomalous gold-in-soil values are commonly associated with elevated copper values with assays up to 0.330 ppm Au.
The Gemini Prospect
Located approximately 5.2km north of Zackly, appears to be hosted primarily within volcanic rocks. This newly discovered prospect was defined in August of 2013, the result of a wide-spaced, property-wide soil sampling program. The Gemini +420 ppm copper-in-soil anomaly, while variable in outline, averages approximately 1.0 km x 1.6 km. Anomalous old-in-soil results tend to occur coincident with elevated copper values with gold assays typically ranging from 0.150 – 0.250 ppm Au.
The Moonwalk Prospect
Work is also planned at PolarX’s 100%-owned Moonwalk prospect, which occurs in the well-endowed Tintina Gold Belt. This gold-rich belt also hosts the Pogo mine (12.3Mt @ 12.5g/t gold), Donlin (1.2 Bt @ 2.2g/t gold) and the Fort Knox mine (283Mt @ 0.44g/t gold).
Located approximately 11.5km north of Zackly, Moonwalk is a gold prospect consisting of altered granodiorite intruding mainly black shale. The intrusive rock and surrounding sediments are commonly altered with local zones of stockwork quartz-sulphide veining. Nineteen soil samples collected from the main altered zone average 1.15 g/t Au over a 400 m by 700 m area.
Chip samples of vein material returned assays up to 30 g/t Au. In addition, a stream sediment samples approximately 2 km downstream from this area assayed 0.24 g/t Au and was accompanied by an outcrop sample of what appears to be altered and veined sandstone that assayed 23.0 g/t Au.
Massive Regional Upside
The entire Alaska Range Project straddles the boundary between the world-class Cretaceous porphyry copper belt and the Tintina Gold Belt. Both host some of the world’s richest and largest copper and gold deposits. PolarX’s 100%-owned Mars, Gemini, Jupiter and Zackly prospects share similar geology to the super-giant Pebble deposit (108M oz gold and 37Mt copper).
The mineralisation encountered in PolarX’s core drilling at Zackly to date, plus the district-scale aeromagnetic data, provides further evidence that the Alaska Range Project may host multiple economic discoveries.
PolarX intends to further define the copper/gold porphyry intrusive targets at Mars, Gemini and Zackly SE with a view to drill testing these as soon as possible.
