Tin ore has been known for some years in auriferous conglomerates at the base of 

 the coal measures at Lankey's Creek, Reefton, Milford and Dusky sounds on the west 

 coast of Otago. In 1888 tin ore was found in gravels, and in situ " associated with 

 gneissic granitoid rocks " in the Remarkable Mountains, Stewart Island. Deposits 

 small, climate wet. In April, 1892, stream tin was found in the gold wash at 

 Humphrey's Gulley, near Hokitika, on the west coast of the South Island.

Stream tin was found in shallow gravels with gold, but was not rich enough to work 

 except with the gold. It averaged less than 1 ounce of stream tin to the " tin- 

 dishful " (sic). In the Tin Range on Port Pegasus tin occurs in " quartz rock " 6 

 inches to 1 foot thick, with " mica rock " above and below. More wolframite than 

 cassiterite is carried by the " quartz rock." Granular topaz, gahnite, sphalerite with 

 " blue faces," and pyrites, accompany the cassiterite.
