The mafic-dominated part of the belt hosts an iron formation
, which defines the Fredart-Gerry Lake 'favourable horizon.' Iron formations
are very often associated with gold mineralization.
The new style of Zn Pb mineralisation has been delineated on the contact between the overlying Frere Iron Formation
and underlying Navajoh Dolomite of the Palaeoproterozoic Yelma Formation.
Tucano belongs to the sub-category of greenstone-hosted gold deposits known as Iron Formation
Hosted Gold Deposits, which includes notable mines such as the historic Homestake mine in South Dakota, where 44 million gold ounces were produced.
The structures include potential shear-hosted gold mineralization and potential multi-element iron formation
mineralization as logged during historic drilling programs.
The property hosts high-grade gold in iron formation
within Archean metasedimentary rocks.
The land interests include a combination of undivided and whole fee interests as well as mineral and surface leases, all lying within the Biwabik Iron Formation
. The acreage acquired is approximately 553 acres and the acreage being leased is approximately 3,215 acres.
Summary: TEHRAN (FNA)- The discovery of Earth's youngest-ever banded iron formation
is changing how scientists understand the evolution of complex life.
Washington, Jan 16 ( ANI ): Researchers have managed for the first time to determine the isotope composition of the rare trace elements Hafnium and Neodymium in 2,700 million year-old seawater by using high purity chemical sediments from Temagami Banded Iron Formation
(Canada) as an archive.
The drilled zone covers an approximate 12 kilometres strike length of the Braemar Iron Formation
within EL4267 and EL3927.
Property expanded to over 30,000 hectares with high potential for both banded iron formation
gold deposits and massive sulphide copper, zinc, silver and gold deposits;
