The Flying Dutchman occurrence is located approximately 19 kilometres south-southwest of Moor Creek and 43 kilometres west of the Cassiar highway.

The occurrence consists of carbonate (plus/minus quartz) veins within the feldspar-phyric diorite phase of the Late Devonian McLymont Plutonic Suite, with several small aplite bodies identified nearby. The zone is characterized by epidote alteration which appears to be related to some of the veins identified and lacking in others. Mineralization consists of chalcopyrite with possible cobaltite, while fracture surfaces display malachite and erythrite. Much of this showing is hosted within highly fractured subcrop. A relatively small area was prospected, and mineralization remains open.

A sample of subcrop graded 0.02 gram per tonne gold, 24.89 grams per tonne silver, 1.62 per cent copper, 0.045 per cent zinc, 0.036 per cent cobalt and 0.014 per cent nickel (Sample B0003741, Assessment Report 39128).

In 2019, Crystal Lake Mining (name later changed to Enduro Metals Corporation) collected 2070 rock samples and 6125 hyperspectral measurements were collected throughout the Newmont Lake property. The area was also extensively covered by the property-wide soil sampling program. A total of 2624 soils samples were collected, with a main focus around the Chachi Corridor (including the Flying Dutchman), Cuba, North/Kerr Glacier, and Thumper areas. The Flying Dutchman occurrence was identified in 2019, on the eastern flank of the Chachi Corridor. Eleven or twelve rock samples were collected in the showing vicinity. East-west soil lines occur nearby to the north and south.
