North Arrow, a Canadian-based exploration company focused on diamond opportunities in Canada, has completed an exploration drilling and till sampling program at its 100% owned Mel Diamond Project, confirming it as a new diamondiferous kimberlite field in Canada. The program represents the first ever exploration drilling of this new kimberlite field and also included work focused on generation of new targets through till sampling and geophysical surveys, the company said.
President and CEO, Ken Armstrong commented “The drilling of kimberlites ML8 and ML345 has confirmed that the Mel Project represents a new diamondiferous kimberlite field in Canada. Over 200 kg of kimberlite is presently undergoing microdiamond analyses and further samples of drill core will soon be submitted for additional microdiamond, mineral chemistry and petrographic analyses. Importantly, the 2018 exploration program also included collection of 447 till samples, doubling the number of samples collected from the Project. Results from these samples will help to define existing and new kimberlite indicator mineral (KIM) anomalies ahead of the 2019 exploration season. The Mel exploration camp remains in place and will support renewed exploration drilling of new and established targets in 2019.”
Six holes (787.5m) were drilled during the 2018 program with kimberlite intersected in five holes testing the ML8 and ML345 targets. Kimberlite ML8, discovered by prospecting in September 2017, was tested by three holes over a 170m strike length. The drill program also resulted in the discovery of kimberlite ML345, approximately 1.5 km south of ML8. The ML345 target is a >400m long. Difficulties with drill serviceability impacted North Arrow’s ability to re-drill ML6, follow up the ML8 and ML345 kimberlite drill intercepts and test additional new targets. Planning has commenced to complete this work in 2019.
