Sample size is 10 cm x 6 cm. The sample shows the characteristic schiller of Bobfergusonite. The darker green phase associated with Bobfergusonite may be Manitobaite. This sample and a suite of others were collected from the loose rock surrounding the #22 Dyke in October 1989. The dyke was still largely intact and phosphate pods containing Bobfergusonite and separate phosphate pods containing the Beusite suite were exposed in outcrop.

Sample size is 10 cm x 6 cm. The colourless, very reflective phosphate on the surface of the sample is identical to samples XRD identified as Metaswitzerite by the ROM. This is the back side of the Bobfergusonite sample. This sample and a suite of others were collected from the loose rock surrounding the #22 Dyke in October 1989. The dyke was still largely intact and phosphate pods containing Bobfergusonite and separate phosphate pods containing the Beusite suite were exposed in outcrop.
