2022-23: VR Resources flew a high resolution drone magnetic survey and drilled 3 DDH totalling 1266 m.
Aug 10, 2023 (Therese Pettigrew) - The kimberlite breccia pipe complex at Northway was emplaced into the English River sub-province of the Archean Superior craton. It is covered by Devonian-aged sandstone, with crater facies at the top of the breccia pipe preserved.

Aug 10, 2023 (Therese Pettigrew) - The magnetic anomaly associated with the kimberlite diatreme breccia intersected at Northway is from 900 - 1,200 metres across. A caldera facies at the top of the breccia pipe is preserved in hole 001. Hypabyssal, coherent kimberlite phases (CK) are evident within xenolith-rich pyroclastic kimberlite (XPK) breccia phases in all three holes. The first two drill holes at Northway intersected various kimberlite breccia phases below a cover of Paleozoic limestone and sandstone. In drillhole NW23-003, 350 m of kimberlite breccia was intersected below a sandstone cover starting at approximately 240 m depth. The hole ended in xenolith-rich kimberlite breccia which is open to depth (VR Resources news release July 6, 2023). Lower crust and mantle-derived eclogite and websterite xenoliths are observed in KPK rock in all three drill holes, together with phlogopite and olivine megacrysts and spherulitic magmaclasts commonly cored by olivine which increase in abundance downwards in both holes 002 and 003. Kelyphite rimmed garnet-bearing eclogite xenoliths occur at 330.8 m near the bottom of hole 002, and in websterite xenoliths with accretionary rims in the lower part of hole 003. Fine grained ilmenite is observed in KPK in hole 001 (VR Resources website, accessed August 10, 2023).

Oct 11, 2023 (Sheree Hinz) - VR Resources Ltd. sent samples from three drill holes for caustic fusion and mineralogy. Microdiamonds were recovered in two intervals within drill hole NW23-003.
Press Release - VR discovers diamonds in 2 separate intervals in Hole 003 at Northway, 600 metres from the discovery in Hole 001
