North Arrow Reports Microdiamond Results From Kimberlite ML8 Mel Diamond Project, Nunavut


VANCOUVER, British Columbia, Nov. 13, 2018 (GLOBE NEWSWIRE) -- North Arrow Minerals Inc. (TSXV-NAR) is pleased to provide an update on the Company’s 100% owned Mel Diamond Project, Nunavut, including initial microdiamond recoveries from surface sampling of kimberlite ML8. The Mel Project is well located, approximately 20 km from tidewater with exploration work conducted from a camp established approximately 140 km south and 210 km northeast of the Hamlets of Hall Beach and Naujaat, respectively. Highlights of this update include:

  • Caustic fusion processing of 129 kg from ML8 has returned 33 diamonds greater than the 0.106 mm sieve size including one diamond greater than the 0.85 mm sieve size;
  • An additional 78 kg of ML8 has been processed with final diamond recoveries underway;
  • Drill core from kimberlites ML8 and ML345 is now in Vancouver and undergoing detailed petrographic logging as well as kimberlite indicator mineral (KIM) and microdiamond sampling;
  • Processing has started on 447 till samples collected during the summer field program. KIM recoveries will be used to better define existing and new targets within the 56,075 ha project area.

President and CEO, Ken Armstrong commented “Microdiamond recoveries from kimberlite ML8 continue to be encouraging, with diamonds recovered across a range of sizes. We look forward to receipt of further sample results from ML8 and ML345, as well as 447 till samples collected as part of an extensive sampling program completed during the 2018 summer program. KIM results from the till and kimberlite samples will be very important for defining priority target areas within the project. The Mel exploration camp remains in place to support renewed exploration drilling of new and established targets in 2019.”

Caustic fusion results for a 129 kg composite sample of kimberlite ML8 are summarized in the following table along with earlier reported microdiamond results from 2017:

The majority of recovered diamonds, including the three largest stones, are white to off-white in colour. Most are fragments or broken with very few intact crystals. The 129 kg sample is part of approximately 220 kg of subcrop and float collected from kimberlite ML8 during the summer 2018 exploration program (please see North Arrow news release dated September 24th, 2018 for details on the program). An additional 78 kg of kimberlite have been processed and final microdiamond sorting is underway. The remaining 13 kg have been submitted for an evaluation of KIM abundance and compositions.

Drill core recovered from kimberlites ML8 and ML345 as part of the 2018 exploration program is now in Vancouver. Detailed petrographic logging is near completion and KIM and microdiamond sampling of the core is underway.

Till samples collected during the field program have arrived at the processing laboratory in Thunder Bay, ON and processing is underway. The 447 till samples provide complete coverage of the entire Mel Project area and results will help better define existing KIM trains and identify new target areas within the property. Results are expected during the first quarter of 2019.

Scientific and Technical Data

Diamond results reported above are based on work completed by Microlithics Laboratories, Thunder Bay, Ontario, and I&M Morrison Geological, Delta, British Columbia. Both are independent mineral process and sorting laboratories. Quality assurance protocols, security and actual operating procedures for the processing, transport and recovery of diamonds conform to industry standard Chain of Custody provisions. As part of North Arrow's ongoing QA/QC programs, concentrate residues and other materials are subject to audit.  Any significant changes to recovered diamond contents will be reported when available. 

The Mel Diamond Project field program was managed by Michael MacMorran, P.Geo. (NU/NWT), Project Geologist for North Arrow. The Company’s diamond exploration programs are conducted under the direction of Kenneth Armstrong, P.Geo. (ON), President and CEO of North Arrow and a Qualified Person under NI 43-101.  Mr. MacMorran and Mr. Armstrong have reviewed the contents of this press release.
