Superior Copper Corp.: 2013 Check Assays on Richards Breccia Confirm Continuity of Grade and Up to 1.67% Cu Over 27 Metres at the Coppercorp Project
24.07.2013 | Marketwire
TORONTO, Jul 24, 2013 - Superior Copper (TSX VENTURE:SPC) reports that check assays have been completed on well-preserved half core segments of three BQ drill holes completed by Aurogin Resources in 1997 and 1998 on the Richards Breccia Copper Prospect, Ryan Township, Sault Ste. Marie Mining Division. The Richards Breccia is located approximately 10 km northeast of the Coppercorp Mine on the recently acquired Jogran Property (see news release April 10, 2013). The Richards Breccia Prospect consists of a near vertically plunging breccia pipe with a surface diameter of 40 metres and a known depth of 75 metres. The vertical extent remains open and the company believes there is good exploration potential below the historic drill holes. The breccia pipe is considered to be Keweenawan in age, similar to the Coppercorp and Tribag Mines, and intrudes Archean rocks of the Batchawana Greenstone Belt.The 2013 check assays resulted in slightly higher composite weighted averages for copper and similar averages for gold and silver compared to historical assays. The check assays also reproduced the positive linear correlation between gold, silver and copper. The most significant results came from AR97-25 with 1.13% Cu, 0.11 g/t Au, and 4.1 g/t Ag over 31.3 metres, and AR98-07 with 1.67% Cu, 0.15 g/t Au, and 5.5 g/t Ag over 26.85 metres. Please note that these are apparent widths.

The copper mineralization is primarily chalcopyrite contained in the matrix between fragments and along fractures. Chalcopyrite is accompanied by pyrite, quartz, biotite, and rock flour. Breccia fragments commonly range in size from less than 1 cm up to 5 cm in a fine grained matrix.
The 1997 and 1998 assays were completed by Swastika and TSL Labs for Aurogin Resources using ICAP Plasma Scan (ICP-OES) for multi-element analysis and fire assay for gold. The 1997 half core sample locations were measured based on the original drill logs and verified where original sample tags were present in the core box. The half cores were carefully quartered and sampled at similar sample spacing as the original samples. Quartered samples were then placed in plastic sample bags with identifying AGAT Labs tags and sealed with a plastic tie. The magnetic susceptibility, carbonate content, and percentage of sulphide minerals were noted in the sample log. In addition, missing or lost sections of drill core were estimated for each box. AR97-25 and AR98-07 had less than 2% missing core sections; AR97-24 had a 22% loss of core between 47 to 64.5 metres. The historical geological logs were reviewed and compared with the drill core and deemed to be acceptable. Samples were placed in rice bags and shipped to AGAT Labs by bus.
AGAT Labs completed multi-element analyses on all samples using Aqua Regia digestion followed by ICP-OES finish. Gold was analysed using a fire assay with ICP-OES finish. Any Au assays greater than 10 g/t was re-assayed by FA-Gravimetric. Silver greater than 100 g/t were re-assayed by FA- Gravimetric finish. Copper greater than 1% was re-assayed by ICP-OES.
The Richards Breccia diatreme intrudes approximately 1 km southwest of the Jogran Porphyry, a Keweenawan age mineralized porphyry containing Cu and Mo which is also on the Jogran Property. The regional area is characterized by extensive fracturing and veining containing chalcopyrite, pyrite and molybdenite along with quartz, carbonate, biotite and chlorite. A 3000 metre drill program is currently proposed for Richards Breccia and Jogran Porphyry Prospects.
