Highlights


Overview

The Mel Project consists of approximately 56,000 hectares of mineral claims on the Melville Peninsula, approximately 140 km south of the community of Hall Beach and 210 km northeast of the community of Naujaat which is also the location of North Arrow's Naujaat Diamond Project. The property is located within 20 km of tidewater and hosts two areas with kimberlite indicator mineral "KIM" trains (North Mel and South Mel) originally defined from over 500 till samples recorded in public assessment files. The mineral trains are composed of pyrope and eclogitic garnets, as well as ilmenite.

Infill and up-ice till sampling was conducted in short summer programs from 2013 to 2016 to define the Mel North KIM train and establish cut-offs for what appears to be at least three distinct indicator trains.  Prospecting at North Mel in late August 2017 resulted in the discovery of a sub-cropping kimberlite body coincident with a magnetic anomaly (ML8).  A 62 kg sample was subsequently processed for micro-diamonds using caustic fusion and yielded 23 diamonds larger than the 0.106 mm sieve size, including a single, colourless diamond larger than the 0.85 mm sieve size (see press release dated Oct. 16, 2017).  In October 2017, North Arrow initiated staking of the area between North Mel and South Mel following the discovery of the ML8 kimberlite expanding the Mel Project landholdings from 7,500 ha to 56,000.

The 2018 exploration program consisted of a total of 787.5 metres of drilling completed in six holes (see map of drill locations).  The program led to the extension of the ML8 kimberlite dike to over 170m in strike length as well as the discovery of the ML345 kimberlite, another dike located approximately 1.5 km south of ML8.  A 224 kg sample of the ML8 kimberlite was extracted from the prospecting discovery location to gain more information on the nature of the diamond population.  The first 129 kg were processed for microdiamonds with the results announced on November 13, 2018.  Core from the 18-ML-03 drill location (testing ML8) displayed multiple cracked country rock and kimberlite intercepts below what is interpreted to be ML-8.  The intersections, like ML8, demonstrate a good mantle sample but different from ML8, they were non-magnetic.  Future geophysics will have to consist of other types of geophysics to give a view into where else we may find this type of kimberlite. Microdiamond and KIM sampling results are pending for these interesections. 

Prior to the 2018 exploration program, Palmer Environmental were contracted to identify evidence of more localized glacial & glacio-fluvial movements. Results of the study guided the selection of the locations of the 442 till samples taken in 2018. The Mel South indicator train in particular should benefit from the study's findings because of its atypical distribution pattern due to fairly static ice movement locally, resembling more of a shotgun blast rather than a typical, uni-directional indicator train.  Lab results from the till samples are due in Q1 of 2019.

Plans for the 2019 follow-up exploration program are currently underway.  North Arrow’s interest in the property is subject to a 1% gross overriding royalty, one half of which (0.5%) can be purchase at any time for $1 million.
