The Raphael (Blue Chip) occurrence is located near the western coast of Flores Island, approximately 4.5 kilometres south- south east of Riley Lake,

The area is underlain by granodiorites of the Upper Paleozoic to Lower Mesozoic West Coast Complex and meta-sediments and volcaniclastics of the Paleocene to Eocene Flores Volcanics.

Locally, quartz veins, varying from 3 to 10 centimetres in width, with in shear zones host galena, sphalerite, pyrite and chalcopyrite mineralization. A ‘high-grade’ zone consisting of a massive sulphides in fractures, over 15 to 25 centimetres width, is hosted by a fault. The zone strikes 176 degrees with a dip of 84 degrees to the east.

In 1988, rock samples of mineralized quartz veins yielded values up to 1.56 grams per tonne gold, 149.7 grams per tonne silver, 1.98 per cent copper, 2.98 per cent lead and greater than 9.99 per cent zinc (Property File - Coronet Metals Ltd. (1990-07-16): Prospectus Report on the Blue Claims).

In 1990, rock sampling of the ‘high-grade’ zone yielded values up to 0.7 grams per tonne gold, 603.4 grams per tonne silver, 4.92 per cent copper, 8.96 per cent lead and 19.9 per cent zinc (Property File- Hawkins, T.G. (1990): Summary of report on Geology, Lithogeochemistry, Soil Geochemistry and Magnetometer Survey on Blue Chip 1 and Blue 1 claims for Coronet Metals Inc.).

The area was originally staked, in 1968, by S. Craig. In 1988, T. Hayes re-staked the claims and prospected the area. In 1989 and 1990, Coronet Metals Inc. completed a program of geological mapping, geochemical sampling, trenching and a magnetometer survey on the area as the Blue Chip claims. This work also identified three geochemical anomalous areas and five magnetic features, three of these coinciding with the geochemical anomalies.
