The Goldcorp high grade zone at the Red Lake mine in northern Ontario is currently the best Canadian example of high-grade gold mineralization. It provides an opportunity to define the fundamental geological parameters controlling the formation of high-grade gold ore and to assist in developing exploration guidelines for such mineralization. This report updates an ongoing study of the Red Lake high grade zone, beginning with a review of the local geological setting and a description of the southeast-trending structural lineament known as the Red Lake mine trend, defined by folds, faults, and an associated corridor of alteration & mineralization. The report then describes the structure, veins, ore zones, and alteration assemblages in the high grade zone and discusses the chronology of gold replacement, gold remobilization, and the geological controls on formation of the high grade zone.

Geological Survey of Canada, Current Research (Online) no. 2002-C27 available in PDF, EPUB and Kindle. This paper reports on a part of the study of the Goldcorp high-grade zone at the Red Lake gold mine, northern Ontario that carried out fluid inclusion microthermometric analyses on a few key samples representing different stages of gold mineralization. The purpose of the study is to provide an initial idea regarding the fluid characteristics before, during, & after the gold mineralization in order to better understand how the deposit was formed and to contribute to the ongoing debate on its genesis. Fluid inclusions were studied from three different mineral phases: pre-ore carbonate, syn-ore quartz, and post-ore euhedral quartz & associated carbonate. The paper reviews the regional & local geologic setting, the petrography of the samples studied, and the study methods employed, and interprets the microthermometric data with discussion of fluid immiscibility, temperature-pressure conditions of carbonate vein formation & silicification, temperature-pressure conditions of euhedral quartz formation, and the evolution of fluid composition.
