Fees and Registration

Description

This workshop will focus on the geological principals of uranium deposit formation, with the presenters’ experience influencing an Africa-centric approach, covering Namibia, Niger, and South Africa in particular, and will include examples from Botswana among others.

The morning will comprise three sessions, with the first focusing on an overview of the major uranium deposit-types globally and set the context for the primary (alaskite type) and secondary uranium deposit sessions that follow, with a focus on African examples. Guy Freemantle will present the primary deposit session and George van der Walt will present the overview and secondary deposit sessions.

These sessions will discuss deposit geology, host rock genesis and characterization, mineralization models and controls, as well as the main methods of exploration.

The afternoon will focus largely on downhole logging methods and grade determination in the first session. The workshop will then finish with a session on the economics and current trends of the uranium market and provide a forum for general discussion and questions.

Lunch will be provided, and all attendees will receive certificates of participation.

Guy Freemantle

The MSA Group

Guy has 13 years of experience, the majority of which has been gained in uranium exploration and mining in southern Africa; Guy includes 3 years professional experience in optical and electron-beam microscopy and X-ray diffraction analyses, primarily in support of process mineralogy projects while at Mintek. Guy's project experience includes geological mapping, radiometric sampling- and downhole surveying, and drill program design and supervision. Project experience highlights include 6-years involvement on the Husab Mine Project, Namibia. This period included: metallurgical- and resource definition sampling campaigns; and targeting, planning, implementation, management, and reporting of exploration- and on-mine drilling campaigns. Guy has interest in ore forming processes, particularly for uranium and pegmatites, mining feasibility studies, process mineralogy, mineral economics, and has recently spent time in mineral prospectivity mapping and target generation projects for base metals. He has recent experience in managing copper and PGE drilling and sampling programs in Namibia, and Zimbabwe, respectively. Guy holds a PhD from the University of the Witwatersrand, which he obtained through the Economic Geology Research Institute of the School of Geoscience in 2015. He is registered with the South African Council for Natural Scientific Professions and is a fellow of the Geological Society of South Africa.

George van der Walt

The MSA Group

George is a registered professional geologist with over nineteen year's multi-commodity experience. He has been involved in early (greenfields) to advanced exploration projects including rare/battery metal (Li, Sn, Ta, Nb) pegmatites in Nigeria, Bushveld Complex PGE-Cu-Ni in South Africa, sedimentary uranium in South Africa and Niger, as well as exposure to rare earth carbonatite and Witwatersrand gold in South Africa. Rare metal pegmatite project management involved co-ordinating a 30-person team across six project areas, covering activities such as mapping, geophysical- and geochemical sampling programs, diamond core drilling, and integration of the data. Outcomes included the reporting of exploration results to international best practice and providing guidance and strategic inputs to Nigerian government entities.

Lia Martinez

Mount Sopris Instruments

Lia is a geophysical engineer with over 11 years' experience in borehole logging geophysics. She works with Mount Sopris Instruments, a borehole equipment manufacturing company located in Denver, USA. She received her B.Sc. degree in Geophysical Engineering with a minor in Physics from the Colorado School of Mines in 2007. She then studied for a Master's degree in Archaeology at the University of Denver (2008-2010). Lia has worked with Mount Sopris Instruments since 2013. Her work includes field training, sales, product development, and technical support for geophysical borehole instrumentation and WellCAD software around the world. Lia speaks Spanish and frequently travels to other countries to teach geophysical logging applications for mining and groundwater applications. She is passionate about Q/C processes for wireline data collection and processing.
