Capsule Geology

The LA ROCHELLE molybdenum prospect is in the southwest part of the Shulaps Range, 300 metres above La Rochelle Lake at the base of the Sebring Peak cliffs, approximately 30 kilometres northwest of Lillooet, B.C.

Mineralization is similar to the nearby Alpine showing (MINFILE 092JNE101), located 1.5 kilometres to the north. The La Rochelle showing is a molybdenum and copper-hosting gossanous quartz vein of variable thickness, 0.5 to 5 metres wide and approximately 300 metres long. The vein is hosted in Mission Ridge Pluton quartz-diorite containing disseminated chalcopyrite, pyrrhotite, pyrite with possible chalcocite and bornite. Most mineralization encountered at this showing appears in the silicified units of the Mission Ridge Pluton.

Miocene Metals Ltd. discovered the La Rochelle prospect in 2011 while completing an exploration program on the Shulaps property. The program consisted of rock, silt and soil sampling throughout the property. Highlights of the rock sampling include outcrop sample K881062, which assayed 3.68 grams per tonne gold and 1.44 grams per tonne silver, and float sample K881063, which assayed 0.96 per cent molybdenum and 1.655 grams per tonne rhenium (Assessment Report 32452).

In 2012, Miocene Metals conducted a program of geochemical soil (112) and rock (20) sampling targeting the La Rochelle area. The program confirmed the presence of structurally-controlled polymetallic fractures hosted in up to 1 metre wide bull quartz veins along the La Rochelle structural trend (Assessment Report 33353). This structural trend extends 7 kilometres northwest from La Rochelle, including the Alpine, Cub, Lisa Dawn mineral occurrences, the Rex (Zeus) deposit, and potentially further north to the Shulaps showing.
