Arctic Star samples up to 0.96% Nb2O5 at Cap

ARCTIC STAR SAMPLES UP TO 0.96% NB2O5 FROM CARBONATITE DISCOVERY AT THE CAP PROPERTY, BC

Arctic Star Exploration Corp. is in receipt of analytical results from its summer 2017 exploration program at its wholly owned Cap property, located approximately 80 kilometres northwest of Prince George, B.C.

The summer exploration program at Cap focused within an area measuring approximately three kilometres by one kilometre and included four drill holes, geologic mapping and sampling, and prospecting. The program was highly successful, resulting in the discovery of an exposure of carbonatite and related rocks with greater than 90 metres of strike length and an estimated thickness exceeding 50 metres. To date, the discovery has been tested by only a single drill hole (see news release dated Aug. 8, 2017).

Prospecting highlights are summarized as follows:

  • The strike length of carbonatite and related rock types encountered in outcrop and drilling totals approximately three kilometres.
  • Five samples contained 0.20 per cent Nb2O5 (niobium pentoxide) with a peak value of 0.96 per cent Nb2O5.
  • Three samples contained over 0.2 per cent TREOs (total rare earth element oxides) with a peak value of 0.39 per cent TREOs.
  • Three samples contained over 5 per cent P2O5 (phosphorus pentoxide) with a peak value of 12.62 per cent P2O5.

The samples referred to above are all selected grab samples, and they are not necessarily representative of the mineralization hosted on the property.

Highlights from drill hole CAP17-004 are summarized as follows:

  • 85.24 metres to 95.66 metres -- 0.35 per cent Nb2O5 across 10.42 metres, including 2.26 metres of 0.63 per cent Nb2O5;
  • 98.87 metres to 118.50 metres -- 19.63 metres of 9.94 per cent P2O5, including 2.55 metres of 20.97 per cent P2O5;
  • 136.1 metres to 138.5 metres -- 2.4 metres of 0.81 per cent TREOs.

The Cap carbonatite complex remains an early-stage discovery with potential for a wide variety of commodities. Initial surface and drill hole samples demonstrate a strong potential for niobium, rare earth element and phosphate. Moreover, as this new carbonatite has only been tested by a single drill hole, there exists a significant potential for further discovery.

Of additional interest are some anomalous concentrations of gold encountered within carbonatite and alkaline rocks during the 2017 exploration. A peak value of 69 parts per billion gold was noted from a pyrrhotite-bearing, calcio-carbonatite sample at a depth of 136.1 metres; this interval also contained in excess of 1 per cent TREOs.

According to Jody Dahrouge, PGeo, president of Dahrouge Geological Consulting Ltd. (consultant to Arctic Star): "The discovery of highly anomalous concentrations of niobium, phosphate and REOs at such an early stage in the exploration of the Cap project should be considered highly encouraging. Future exploration at Cap will follow up on surface samples that contained highly anomalous concentrations of niobium and which may be related to drill hole CAP17-004."

Mineralized carbonatite systems have been mined for and/or are potential sources for commodities such as rare earth elements (REEs), niobium, tantalum, copper, nickel, iron, titanium, zirconium, platinum group elements (PGEs), gold, fluorspar, lime, sodalite and vermiculite. Strong demand growth, stemming in part from a number of green energy solutions, has placed upward price pressure on a number of those commodities associated with carbonatites.

Some of the more notable active and past-producing carbonatite deposits known around the world include Palabora (copper, nickel, gold, PGEs and other), South Africa; Bayon Obo (REEs, iron, niobium and fluorspar), China; Araxa (niobium), Brazil; Cargill (phosphate), Canada; Niobec (niobium), Canada; Mountain Pass (REEs), United States; and Mount Weld (REEs), Australia.

Further details will be released as they come available.

Quality assurance/quality control

Drill holes reported in this press release were drilled using NQ-sized core. Samples were then cut into equal halves using a diamond core saw. One-half is being stored near the project and the other half is sent for analysis at Actlabs of Kamloops, B.C. A systematic quality control procedure was implemented for the drill core, where quarter core duplicates and blanks were inserted at a rate of one every 20 samples. Laboratory standards and standard laboratory quality control procedures were relied upon for the drill core and prospecting rock samples. Samples received at Actlabs are first crushed up to 90 per cent passing two millimetres. Further, samples were analyzed with analytical codes 8-REE, 8-XRF (tantalum and niobium) and FA-AA. The 8-REE method requires the sample to be ground to 95 per cent passing minus 200 mesh and then treated with lithium metaborate/tetraborate fusion with subsequent analysis by ICP and ICP/MS. The 8-XRF method fuses the pulverized split sample with a lithium metaborate/tetraborate flux in platinum crucibles with the molten glass cast into a glass disc in platinum crucibles. These glass discs are analyzed by XRF. A 30-gram subsample of the pulverized sample was subjected to Actlabs' 1A2 analysis (fire assay with AA finish).
