  • GSPR has obtained historical data from historical operators and is consolidating and reinterpreting this data to support a Summer 2020 Drill program

History

  • Copper mineralization has been known in the area now covered by the Alwin property since late in the 19th century. Small-scale mining was conducted in the property area during the early 20th century. Recent exploration and mining was conducted during two periods: from 1967 to 1982 and from 2005 to 2008.
  • From 1967 to 1970: 6,940 m of surface diamond drilling in 81 holes was drilled along the main Alwin mineralized trend, and 5,860 m of underground drilling in 119 holes was completed in 1,400 m of development workings in the Alwin mine.
  • 1980, Dekalb Mining Corp. expanded the capacity of the mill to 700 tons (636.4 tonnes) per day and resumed mining of the main Alwin mineralized trend. Total production was 155,000 tonnes grading 1.54% copper. Mining was suspended in 1981 due to low copper prices. At the conclusion of mining, a trackless development decline had been extended to a depth of 270 m below surface (to an elevation of 1,400 m a.s.l.) and 3,935 m of drilling had been completed in 76 underground holes. Dekalb calculated a resource around the mine workings after mining terminated. A summary of this historical resource estimate calculation was reported to be a total of 390,000 tonnes of mineralization grading an average of 2.5% copper after factoring for 25% dilution. No cut-off grade was reported.
  • This historic resource was not calculated to current specifications and standards, and it is not compliant with National Instrument 43-101. It can not be deemed to be a current resource and it can not be relied upon. As noted further, the Company is not considering the estimate as current and further drilling is needed in order to upgrade the historical resource estimate.

2008 Drilling:

  • From 2005 until 2008 San Marco Resources Inc. explored the Alwin property. Work included 3-dimensional induced polarization and soil surveys, and geological mapping that covered the whole property area. In 2008, San Marco Resources Inc. conducted 1,304.5 m of NQ diamond drilling in 8 holes.
  • The first five holes (DDH 1 to 4A) were drilled into the main mineralized trend near the eastern part of the mine workings. The last three holes (DDH 5 to 7) tested induced polarization anomalies north and northwest of the mine. See the accompanying table for significant drill intersections.
