Transition Metals initiates drilling at Aylmer Cu-Au Project, Sudbury

Aug 18, 2022

Transition Chief Operating Officer Greg Collins, P.Geo. stated "We believe that the Aylmer breccia system may be the high-level expression of a much larger, vertical intrusion driven, mineralized system at depth. The brecciation and alteration we are seeing is similar to breccia zones being explored nearby by companies including Inventus Mining and MacDonald Mines which are reported to host broad intervals of elevated copper, cobalt, gold and silver values. We are pleased that funding for this drilling will be supplemented by grants provided by the Ontario Junior Exploration Program (OJEP) designed to encourage exploration for new strategic metal deposits in Ontario.

Transition Metals Corp (TSXV: XTM) ("Transition", "XTM") is pleased to announce that drilling has commenced at its Aylmer project consisting of 119 mining claims covering 3,312 hectares north of Lake Wanapitei approximately 50 kilometers northeast of Sudbury, Ontario. 

Work by the Company has outlined a large, highly altered and mineralized breccia system that covers an area of approximately 1000 m by 400 m target system that extends to a vertical depth of at least 400 metres (Figure 1). Based on deep penetrating audio frequency magnetotelluric data (AMT), this intrusive breccia appears to punch up through Huronian stratigraphy from more than 1 kilometer of depth below surface (Figure 2). The breccia system occurs within a north-trending, regional structural zone interpreted to be 14 to 15 kilometre wide. This structure has associated widespread regional sodic-altered rocks and occurrences of gold-copper-bearing quartz veins grading up 5.93% Cu (See Company news releases of November 2, 2020 and July 19, 2020). 

Three initial targets as shown in Figures 1 and 2 have been delineated for a 1,250 metre diamond drill program at Aylmer:

1)  Hilltop Breccia Exposure

This is an impressive breccia exposed on the hilltop that is characterized by subangular to subrounded metasedimentary fragments hosted within a fine-grained matrix of iron-carbonate and quartz. The breccia target will be tested by a fan of west-trending drill holes oblique to the contact but perpendicular to the sediment stratigraphy in which the holes are collared.

2)  Copper Trench Breccia

The Copper Trench Breccia located approximately 200 metres to the south of the Hilltop Breccia, is an albite-chlorite-replaced breccia with laminated metasedimentary fragments within a quartz-iron carbonate-chalcopyrite-chlorite matrix. Drilling will be oblique to the north-south trend of the breccia and extend northward to also test an area of pervasive and intense alteration located to the northeast.

3)  Deep Rooted Magnetotelluric (MT) Anomaly.

The MT anomaly is located approximately 775 metres south of the Copper Trench Breccia. Drilling will test the MT anomaly at a vertical depth of about 200 metres. At depth, this anomaly appears to connect to a larger, strong MT anomaly at approximately 1,000 metres depth.
