SUDBURY PLATINUM CONTINUES TO INTERSECT NI-CU-PGM MINERALIZATION AT AER-KIDD

Sudbury Platinum Corp. and Transition Metals Corp. have released the latest assay results from drilling completed at their Aer-Kidd project, near Sudbury, Ont. In March of 2015, the company disclosed results from the first three holes completed on the property, two of which included encouraging intersections of elevated copper, nickel and platinum group (nickel-copper-platinum group metal) mineralization (refer to news release dated March 2, 2015).

Scott McLean, PGeo, chief executive officer of SPC, stated: "We continue to be encouraged by the precious metal content of the mineralized zones. We have now defined mineralized trends based on geology, geophysics and mineralization that highlights the further potential at depth. Pursuit of similar trends at depth at Totten and Victoria adjacent to the Aer-Kidd property has resulted in two of the most significant discoveries in the Sudbury camp in recent years. Our plan moving forward is to pursue these corridors at depth, where we feel that there is excellent blue-sky exploration potential."

This release discloses assay results from three holes. AK-14-001B and AK-14-001C were follow-up wedge holes further testing the mineralization intersected by AK-14-001A. AK-15-003 is a new hole, which tested a conductive target located under the past-producing Robinson mine. To date, nine holes totalling 6,158 metres have been completed with assay results pending for an additional three holes.

Highlights:

• AK-14-001B intersected 7.40 metres containing 0.33 per cent nickel, 0.45 per cent copper and 2.27 grams per tonne platinum group metals (platinum plus palladium plus gold), including 0.60 metre grading 0.33 per cent Ni, 1.38 per cent Cu and 4.19 g/t PGM, approximately 30 metres updip and east of AK-14-001A.
• AK-14-001C intersected 18.0 metres containing 0.39 per cent Ni, 0.59 per cent Cu and 1.84 g/t PGM, including 4.0 metres grading 0.27 per cent Ni, 1.13 per cent Cu and 4.73 g/t PGM, approximately 50 metres updip and east of AK-14-001B.
• AK-15-003 intersected 9.15 metres containing 0.67 per cent Ni, 0.99 per cent Cu and 1.46 g/t PGM, 200 metres below the past-producing Robinson mine.

Discussion of results

AK-14-001B (1,044 metres: wedge cut at 531 metres): The hole intersected the offset dike approximately 30 metres updip and east of the AK-14-001A intersection (8.10 metres of 1.04 per cent nickel, 0.75 per cent copper and 2.40 grams per tonne PGM -- see March 2, 2015, news release) and intersected the quartz diorite dike over a core length of 81.05 metres from 817.5 to 898.55 metres. Amphibolite-rich quartz diorite was intersected over a core length of 13.05 metres from 882.3-895.35 metres and contained widespread blebby Ni-Cu sulphide mineralization (up to 25 per cent) in between large amphibolite fragments. Assay results returned a 7.40-metre zone of 0.33 per cent Ni, 0.45 per cent Cu and 2.27 g/t PGM from 885.85 to 893.25 metres, including a higher-grade section of 0.33 per cent Ni, 1.38 per cent Cu and 4.18 g/t PGM over 0.60 metre from 892.65 to 893.25 metres.

AK-14-001C (969 m: wedge cut at 479 metres): The hole intersected the offset dike approximately 50 metres updip and east of the AK-14-001B intersection and intersected the QD dike over a core length of 79.65 metres from 786.1 to 865.75 metres. AIQD was intersected over a core length of 22.0 metres from 837.0 to 859.0 metres and contained widespread blebby sulphide mineralization, as well as zones of semi-massive sulphides that wrap around large amphibolite fragments. Assay results returned an 18.0-metre zone of 0.39 per cent Ni, 0.59 per cent Cu and 1.84 g/t PGM from 836.0 to 854.0 metres, including a higher-grade section of 3.39 per cent Ni, 0.36 per cent Cu and 2.20 g/t PGM over 0.60 metre from 843.2 to 843.8 metres.

Follow-up borehole electromagnetic surveys in AK-14-001B and -001C indicate that the high conductivity area associated with the sulphide intersections continues updip and east of the current drilling. The results indicated additional mineralization associated with this zone remains favourable for further definition and expansion both updip and downdip along this trend.

AK-14-003: The hole was designed to test an area of high conductivity and favourable geology approximately 200 metres downdip of the historical Robinson mine. The hole intersected the QD dike over a core length of 115.25 metres from 516.9 to 632.15 metres. AIQD was encountered over a core length of 60.1 metres from 543.0 to 603.1 metres and contained widespread blebby sulphide mineralization (up to 25 per cent) in between large amphibolite fragments. Assay results returned a 9.15-metre zone of 0.67 per cent Ni, 0.99 per cent Cu and 1.46 g/t PGM from 566.45 to 575.60 metres, including a higher-grade section of 1.11 per cent Ni, 2.36 per cent Cu and 2.92 g/t PGM over 1.45 metres from 568.55 to 570.0 metres. A BHEM survey was completed in hole AK-14-003 and defined a strong offhole conductor approximately 50 m downdip of the hole that has an orientation and position consistent with those of the down plunge projection of the Robinson mine. The results confirm that mineralization exists beneath the lowest underground workings of the Robinson mine and highlights the exploration potential of this trend at depth.

About the Aer-Kidd property

The Aer-Kidd property is located about 20 kilometres southwest of Sudbury, Ont., and covers a 1.4-kilometre section of the Worthington offset dike in an area with a rich mining history, dating back to the 1800s. The property is approximately 2.6 kilometres along strike to the northeast of Vale's Totten mine (10.1 million tonnes grading 1.5 per cent Ni, 1.97 per cent Cu and 4.8 g/t PGM) that is currently in production and 4.3 kilometres to the southwest and along trend of KGHM's Victoria project (14.5 million tonnes grading 2.5 per cent Ni, 2.5 per cent Cu and 7.6 g/t PGM) which is currently being developed. The Aer-Kidd property hosts the former producing Howland pit and the Robinson and Rosen mines, which were small deposits mined down to a maximum depth of 300 metres.

Qualified person

The technical elements of this news release have been approved by Grant Mourre, PGeo (APGO), a qualified person under National Instrument 43-101. All samples were analyzed in Vancouver by ALS Chemex. Platinum, palladium and gold values were determined together using standard lead oxide collection fire assay and ICP-AES finish. Base metal values were determined using sodium peroxide fusion and ICP-AES finish. Silver values were determined using an aqua regia digestions and an AAS finish. A certified reference material standard, blank or duplicate is inserted on every 10th sample in the following order: CRM, blank, CRM and duplicate. The cycle repeats every 40 samples, thus ensuring that 10 per cent of samples submitted are control samples. Laboratory checks are also done with one sample in every batch (maximum of 40 samples) being submitted to an external lab for comparison.
