Stornoway Diamond announced the discovery of kimberlite at its 100% owned Adamantin Project located approximately 100km south of the Renard Diamond Project and 25km west of the Route 167 Extension in north central Québec. To date 11 distinct kimberlite bodies have been identified, with intersections of up to 13.7 meters of undiluted kimberlite, and are interpreted to represent a new center of kimberlite emplacement located proximal to, but distinct from, the Renard kimberlite cluster.
Till sampling at Adamantin during 2015 confirmed the presence of indicator mineral anomalies interpreted to be sourced from undiscovered kimberlites with diamond potential, with one till sample containing a diamond from the +0.25mm-0.50mm size fraction. Drilling commenced on March 20, 2016, with a light weight, helicopter portable, reverse circulation drill rig designed to test multiple geophysical targets within a broad indicator mineral anomaly.
The Adamantin Project now comprises 15,139 hectares of claims following recent additional acquisitions. In total, 72 targets identified from airborne geophysical data were tested with two RC rigs drilling shallow holes. RC drilling produces small chips of rock that are brought to surface by air pressure, and is well suited for the rapid and economical testing of multiple targets involving frequent re-positioning.
Of note, drilling at adjacent geophysical anomalies AD-50, 51 and 52 suggests the presence of a single, shallowly dipping (5-10 degrees), tabular body with an apparent true thickness of approximately 10 meters. This body lays 6-12m below surface, extends over a minimum NW-SE strike extent of 260 meters and is open in all directions. Approximately 870kg of kimberlite chips were recovered from the AD-50/51/52 body, with samples varying from 20kg to 300kg in size collected from the other 10 discoveries. These will now be sent for diamond recovery to give a preliminary indication of the diamond content of each body.
