The Aye occurrence is located on Reserve 13, south of Quiltanton (Divide) Lake in the upper Highland Valley. There is no outcrop in the area and overburden depths of 150 to 180 metres are reported from drill holes.
The area is underlain by Bethlehem phase granodiorites of the early Jurassic - late Triassic Guichon Creek Batholith.
Locally, drilling in holes 4 and 6 intercepted disseminated chalcopyrite and molybdenite in hydrothermally altered Bethsaida granodiorite (Geology, Exploration and Mining in British Columbia 1969).
In 1969, a sample (002) of split core assayed 0.14 per cent copper, while visual estimates of drill core yielded an average of 0.32 per cent copper over the final 44.7 metres of hole no. 4 (Property File - Kavanagh. P.M. [1969-10-31]: Re: Darhawk Mines Indian Reserve No. 13 - Highland Valley). Also, at this time, a nearby drill hole (L10) performed by Bethlehem immediately west of the Aye claim was reported to have yielded 0.39 per cent copper over 189.3 metres, after 101.4 metres of overburden (Property File - Kavanagh. P.M. [1969-10-31]: Re: Darhawk Mines Indian Reserve No. 13 - Highland Valley).
During 1966 through 1970, Thunder Bird Mines Ltd. and later Dark Hawk Mines Ltd. examined the area as the Aye claims and completed at least 14 drill holes.
