TORONTO (miningweekly.com) – Project generator Transition Metals' latest programme of diamond drilling at Sunday Lake, 25 km north of Thunder Bay, Ontario, has confirmed continuity of platinum group metal (PGM) mineralisation over an area about 700 m long and 300 m wide, at depths tested between 370 m to 800 m below surface.

The programme – a joint venture owned 75% by Impala Platinum (Implats) and 25% by Transition, and funded by Implats – was started in the fall of 2014 and consisted of three holes totalling 2 074 m to further evaluate the extent and quality of the Discovery zone, first announced in January last year.

Transition explained on Monday that the mineralisation remained open for further expansion in all directions with some of the best grade thickness intercepts remaining open at relatively shallow depths to the east and to the west.

Hole SL-14-006 intersected 421.9 m of the Sunday Lake Intrusion (SLI) from 414 m. From 806.4 m to 835.9 m pyrrhotite and chalcopyrite mineralised ultramafic and gabbroic rock along and above the basal contact were encountered, returning 10.9 m of 2.3 g/t PGMs between 825 m and 835.9 m. Within this unit a higher-grade zone returned values of 3.29 g/t PGMs over 4.9 m from 831 m to 835.9 m.

While hole SL-14-007 did not intersect significant mineralisation, SL-14-008 intersected 284.9 m of the SLI from a depth of 393.9 m to 678.8 m. Geologists encountered pyrrhotite and chalcopyrite mineralised ultramafic and gabbroic rocks along the basal contact from 655.6 m to 678.8 m, returning 17.8 m of 1.95 g/t PGMs.

Within this unit a higher-grade zone returned values of 3.3 g/t PGMs over 7 m from 656.6 m to 663.6 m and 6.6 g/t PGMs over 1 m from 661.6 m.

To date, less than 10% of the prospective SLI had been tested with diamond drilling. Drilling had, however, highlighted the excellent potential of the intrusion to host a significant PGM resource. Transition noted that further drilling was required to expand the known mineralised zone and realise the intrusion's economic potential.

The SLI was a large intrusion similar to other intrusions in the area that were known to be mineralised. Those intrusions included Panoramic Resources’ nearby Thunder Bay North PGM project, Rio Tinto’s Tamarack, in Minnesota, and Lundin Mining’s Eagle mine, in Michigan, to which the Sunday Lake project had shown similarities.
