About GeoMin

Director Jovan Grubin is a professional engineer of technology and a business manager

with 20+ years of working experience at highest standards of safe and ethical conduct in

complex business environments. Most recently Jovan organized the incorporation of the

start-up Lithium LI Holdings (PGZ JV) subsidiaries in Serbia and Bosnia Herzegovina. As

respective country directors, he worked diligently on stakeholder engagement activities

and day-to-day company management, securing legal and social license to operate in both

countries.

Bob Kellie, former Rio Tinto chief geologist, has made himself available to assist and

liaison with technical matters during the initial projection transition and is also available for

subsequent exploration. Bob is a professional geologist with a track record of

demonstrated success in global minerale exploration and evaluation. He directed efforts to

target, acquire and test prospective exploration licenses in the Balkans, leading to the

discovery of both Rio Tinto’s Jadar B/Li deposit and the Valjevo B/Li prospect in Serbia.

Bob has been intermittently exploring for evaporates in the Balkans since 1997.

The Jantar Group, headed by Dusan Simic, has been contracted to provide project

technical control and supervision over exploration activities as mandated by Serbian

mining Law. The Jantar Group is the region's leading mining services company providing

oversight for all exploration and mining activities.
