The TWM area includes the Timmins Deposit, Thunder Creek, and Highway properties for a total area of approximately square kilometres, or approximately 1, hectares. The majority of the property is situated within Bristol Township (1, ha), with approximately hectares located in Thorneloe Township and 36 hectares in Carscallen. The deposit is hosted within a nested suite of 3 Ma quartz monzonite to quartz monzodiorite intrusions. Currently the units of the Grasberg are divided into three groups of intrusions. From oldest to youngest, these are the Dalam, the Main Grasberg Intrusion and the Kali. The units are all porphyritic and very similar petrographically.

The Hemlo West Property is located in the west end of the Hemlo greenstone belt approximately 25 km west of the Hemlo mines. The property covers the western extension of a regional-scale deformation zone and favourable gold trend coined the "Hemlo-Heron Bay Shear Zone" that also hosts the Hemlo deposit.

In particular, the lithostratigraphy of the area is established, the nature of the lithologic units spatially closely associated with the ore and the protolith of the ore are determined, and the deformation history and the three-dimensional geometry of the area are by: The vein-forming fluids for gold deposits in metamorphic environments are uniquely CO 2 and 18O rich, with low to moderate salinities.

Phanerozoic and Paleoproterozic ores show a mode of formation temperatures at ° to °C, whereas Late Archean deposits cluster at about °to °C. Muir, T.L.

Mineral Deposit Models. For descriptions of metallogenic belts, lode mineral deposits are classified into various models or types.

Detailed descriptions are provided in the companion paper by Obolenskiy and others (). The following three main principles are employed for synthesis of mineral deposit. A good example is the discovery of the Las Lagunas Norte deposit in the Alto Chicama district of northern Peru, where high-sulfidation epithermal mineralization is hosted in clastic sedimentary rocks rather than in volcanic rocks, as favored by the classical model.
