Mountain Province finds new kimberlite in Kennady North exploration programme

Published by
Global Mining Review,

Mountain Province Diamonds Inc. has announced positive exploration results for its 100%-held Kennady North project. The Kennady North Project includes over 113 000 ha. of claims and leases that completely surround the Gahcho Kué Diamond Mine. The 2022 exploration program focused on new discoveries through a detailed analysis of both new and historic geophysical, geological, and kimberlite indicator mineral (KIM) data. Interim results for the winter program that focused on geophysical surveys and drilling of lake-based anomalies were reported previously. The summer programme focused on drilling land-accessible geophysical targets and on follow-up till sampling over KIM anomalies generated from the 2021 till sampling program.
The new KE kimberlite area discovered
  • New and distinct occurrence that is located roughly 450 m east of the Kelvin kimberlite.
  • Defined by three drillholes that have confirmed a series of hypabyssal kimberlite sheets (HK) with a maximum HK intersect of 2.13 m, that appear to be new and distinct from the nearby Kelvin deposit.
  • Further drilling of the KE kimberlite is currently planned for the 2023 exploration program.
Over 5000 m of exploration drilling
  • 25 of 35 exploration drillholes intersected kimberlite.
  • Eight volcaniclastic kimberlite intersections on the North Anomaly.
Geophysical surveys
  • 1291 line-km of airborne magnetics and electromagnetics.
  • 189 line-km of high-resolution resistivity (ARRT) data.
  • 30 line-km of ground magnetics.
  • 3139 ground gravity and 161 bathymetry measurements.
  • Historic HLEM and magnetics identified the KE kimberlite.
Kimberlite indicator minerals
  • Over 600 strategic till samples processed and assessed from 2021.
  • Over 300 follow-up till samples in 2022 confirming the 2021 sampling strategies.
  • Positive KIM dispersals identified new areas for geophysics and drilling.
Metals exploration
  • Intersection of a hydrothermal breccia with quartz veining and sulfides, which remains under review.
  • Glacial sediment geochemistry identified areas of interest.
  • A new claim block was added after a detailed review of historical drill logs was conducted and determined that a drill hole was logged in the early 1990's as an intersection from 108 to 176 m of granite/quartz syenite with magnetite.
