The Phantom occurrence is located within the Groundhog coalfield, an oblong 30 by 80 kilometre area extending southeastwards from the headwaters of the Klappan and Little Klappan rivers to Groundhog Mountain in the Skeena Ranges. Access is from the Stewart Cassiar highway, north of Tatogga, to the Klappan road that crosses and follows the east side of the Skeena River on the old BCR grade south to within 15 kilometres of the property. A rough ATV trail joins the end of the Klappan road to the property.

The Phantom property is situated in the Bowser Basin, a large area of clastic rocks located north of the Skeena Arch and south of the Stikine Arch. The area is primarily known for the large Klappan and Groundhog coalfields.

The claims cover at least 30 quartz veins, 30 to 100 centimetres in width and spaced 3 to 6 metres apart within sandstone, siltstone, and mudstone sequences. Specimen quality quartz crystals are found in vugs and in channels in the quartz veins. The showing was discovered in 1989 and is believed to be the only British Columbian location where specimens include rare phantoms, rainbow crystals, and double terminated crystals “Diamonds”.

The quartz crystals on the Phantom property were discovered by Ralph Keefe and Dan Ethier on September 8, 1989 during a regional prospecting and sampling program sponsored by the Prospectors Assistance Program (PAP) offered through the BC Geological Survey. The showings were modestly developed by Mr. Ethier from 1990 to 1993 using hand methods. During that time, a total of 1518 kilograms of A-B grade material was mined with an estimate of 25 per cent waste. Inventory sold in 1992 totalled $4593.28.
