Capsule Geology

The New York Central showing is located on the slopes of Jubilee Mountain, 3 kilometres southeast of Ymir. The main working on the claim is an old tunnel.

The area is underlain by quartzites and argillites of the Lower Jurassic Ymir Group which occur as roof pendants within Late to Middle Jurassic granite of the Nelson Intrusions (Nelson batholith).

A sheared, pyritic quartz vein, 0.45 to 1.0 metre wide, occurs along the contact of the granite with the sediments. The trend is generally northeast about 015 degrees with a westerly dip of about 50 degrees.

This showing is reported to be similar to the Iowna (082FSW065) and Nevada (082FSW064) occurrences which have pyrite as well as sphalerite and galena, however, sulphide mineralogy and metal grades are not documented.
