Abstract Canadian Malartic is a large-tonnage, low-grade Archean gold deposit (16.3 Moz, 1.08 g/t Au) located in the Abitibi region of Quebec, Canada. A large part of the mineralization is hosted in the Pontiac Group metasedimentary rocks, which consist of mudstones to greywackes at upper greenschist to amphibolite facies. In exploration and production environments, these lithologies are challenging to characterize by conventional core logging methods, while in a research setting thin section-si...

The Area 41 copper-platinum-group element (PGE) occurrence was discovered in 2006 at the northwestern margin of the Coldwell Complex. The discovery was significant because of the sizable mineralized intersections, including 1.4 ppm Pd + Pt and 0.32% Cu over 43 m. Since then, exploration along the northern margin has resulted in the discovery of several other Cu-PGE zones with similar grades and host rocks. Field relationships, drill-core logging, petrography, and lithogeochemistry indicate that ...

Abstract The Pontiac Subprovince is located in the Superior Province, south of the Abitibi Subprovince. The metasedimentary rocks of the Pontiac Group are characterized by a Barrovian metamorphic gradient increasing from north to south from biotite- through garnet- to staurolite-zone conditions. The Pontiac Subprovince has been interpreted as an accretionary wedge or alternatively as an exotic terrane that was tectonically docked to the Abitibi Subprovince during Archean subduction. However, few...

Abstract Exploration for mineral deposits is becoming increasingly difficult, requiring the use of novel approaches that are reliable and cost-effective. One such approach is the use of vein-hosted mineral chemistry. A number of studies have described the use of vein-hosted mineral chemistry as an exploration tool, but few have assessed a variety of factors that may have controlled the composition of these minerals. An understanding of why and how the composition of minerals varies, however, is ...

Abstract Evolved granites and pegmatites are important sources for critical metals, including niobium (Nb) and tantalum (Ta). The ore deposits that are commonly associated with these granitic rocks are commonly enriched in phosphorous (P) and boron (B), yet there are few experimental constraints on the influence of these fluxing compounds on ore forming processes. Here, the effects of phosphorous (P), boron (B), temperature and melt alkalinity on the solubility of manganocolumbite (MnNb 2 O 6 ) ...
