IOCG Deposits – The alkaline granite association, in combination with anomalous Rare Earth Elements (REE), uranium and thorium (plus the presence of hematitic iron alteration) suggest possible Iron Oxide Copper Gold (IOCG) deposits in association with the Hare Hill Granite Complex at Lost Pond.

Iron-oxide copper-gold (IOCG) deposits formed along extensional and collisional cratonic margins, both modern and ancient, both incipient and mature, which promoted partial melting of deep continental crust to uppermost mantle rocks and production of magmas of a wide range of compositions. They are most abundant in Proterozoic terrains, although Phanerozoic and Archean examples are present. IOCG deposits occur in felsic to intermediate volcano-plutonic terrains, but in some cases there is a spatial, if not direct genetic relationship to mafic and ultramafic magmas as is the case with Olympic Dam and carbonatite-associated Fe-phosphate-REE deposits (e.g. Bayan Obo. They are often associated with the root zones of volcanic centers, and some IOCG deposits have many similarities to Fe-rich porphyry copper systems. Also, there is a continuum of IOCG deposits types and forms ranging from deeper-seated replacement and breccia styles to iron-oxide rich epithermal type deposits. They formed along and at the intersections of major crustal lineaments, and often display strong structural control over their morphology and ore textures. The wide range of geotectonic settings and associated magma compositions generate an equally complex range of deposit sub-types. Different investigators have placed a range of deposit sub-types within the IOCG class including:
