The Two Star showing is located 32 kilometres south of Nelson, just east of Ymir. Development began on this property in 1933.
The area is underlain by granodiorite of the Middle to Late Jurassic Nelson Intrusions, a small pendant of Jurassic Ymir Group argillite occurs near the showing.
The occurrence is on the strike extension of the Yankee Girl (082FSW068) and Dundee (082FSW067) vein systems. The occurrence comprises a vein in a strong quartz filled shear which strikes 055 degrees within argillite. The vein is wide and hosts pyrite and fine-grained galena and sphalerite.
Kingsvale Resources Ltd. optioned the property in 1988 and conducted trenching and sampling; they dropped the option in 1989. The sampling program in 1988 from the Evening Star shaft resulted in an average assay of 10.11 grams per tonne gold and 118.27 grams per tonne silver over 2.4 metres (George Cross News Letter No.216, 1988). Assays to the west of the shaft were higher.
There has been no recorded production from this occurrence although there has been a great deal of surface and underground development.
