The Tectonics, Architecture and Metallogeny of the Proterozoic of NE South America
A new 3-year AMIRA Global
collaborative research program has been given the go-ahead by three companies to continue the South American eXploration Initiative (SAXI), with a project start date of the 1st of October 2020. Additional sponsors may still join the project at this stage.
The SAXI Stage 1 project was developed at industry request to enhance the exploration potential of the Guiana Shield and neighbouring terranes through an integrated program of research and data gathering into its ‘anatomy’. The initiative considered the whole of the Guiana Shield, which spans the following countries: Brazil, French Guiana, Suriname, Guyana, and Venezuela. Additional neighbouring regions such as the Borborema Province in NE-Brazil may be included based on sponsor support. Key motivations for undertaking this initiative were to assist exploration companies in focusing their activities in areas of maximum prospectivity and to help the local Geological Surveys in the region to build capacity and enhance their capability in their role of providing pre-competitive data and information. An additional aim of the project is to build a matching knowledge base that can be combined with the WAXI database to produce a seamless coverage for the two regions.
Stage 2 builds upon the successes of the Stage 1 project to provide a once in a generation opportunity to tackle some of the major outstanding questions related to the tectonics and metallogenesis of the region. Stage 2 is being funded by an AMIRA Global
consortium of sponsors: AngloGold Ashanti, Barrick
. The project is a collaborative effort lead by Mark Jessell
from the Centre for Exploration Targeting (UWA) and supported by CET researchers Nico Thebaud, Steffen Hagemann, Luis Parra-Avila, Jean-Paul Bout
(new UWA-CET PhD candidate), and involvement of Mike Tedeschi
(ex UWA-CET PhD candidate) and now postdoctoral fellow at Laurentian University, Canada; along with 15 research partners from Brazil, Canada, France, French Guiana, Guyana, the Netherlands, and Suriname.
This initiative offers a special opportunity for companies to cooperate in funding a project that will ultimately provide not only new geological information but also a new geological framework and exploration insights. These will assist sponsors in exploring a highly-prospective region extending across several countries. Each of these countries uses a different administrative language, which has historically made it difficult for most companies to acquire and compile exploration of relevant data and information to enable them to develop knowledge-based terrane selection strategies.
The Proterozoic Guiana Shield extends over five countries in north-eastern South America (Venezuela, Guyana, Suriname, La Guyane (France) and Brazil) and represents the geological extension of the West African Craton. Between 2006 and 2010 the AMIRA P934 West African Exploration Initiative (WAXI) has built up an extensive exploration database for West Africa that is now out of confidentiality. There is no publically available equivalent database for the Guiana Shield and neighbouring terranes, and the aim of this project is to build a matching knowledge base that can be combined with the WAXI database to produce a seamless coverage for the two regions.
The initial focus will be on Guyana and Suriname although as additional sponsors join we expect the research to cover the whole of the Guyana Shield and even extend to the Borborema Province in NE Brazil. The overall aim of South American Exploration Initiative is to enhance the exploration potential of the region through an integrated program of research and data gathering into its ‘anatomy’. Key motivations for undertaking this initiative are to assist exploration companies in focusing their activities in areas of maximum prospectivity and to help local Geological Surveys and Universities in the region in their role of providing pre-competitive data and information.
