TANTALEX Acquires Prospective Cobalt Property in Line With Strategy to Diversify its High-Tech Minerals Portfolio

TORONTO, ONTARIO and MUNICH, GERMANY--(Marketwired - Sept. 20, 2017) - TANTALEX Resources Corporation (CSE:TTX)(CSE:TTX.CN)(CNSX:TTX)(FRANKFURT:1T0) ("TANTALEX" or the "Corporation"), is pleased to announce that its wholly owned subsidiary, United Materials Congo SARL ("UNITED MATERIALS" or "UMC") has acquired an important mining claim namely PR 13634, KASEKA Cobalt Property ("KASEKA"), known to be highly prospective for copper and cobalt, which was previously owned by Gécamines SA.

The property is located within the mining friendly region of Kolwezi in the south of the Democratic Republic of Congo (DRC) and is home to several large deposits. It is situated within the prolific Katangan Copperbelt and is defined as a syncline geological formation for which its southern part intersects the Kansuki Fault, and its northern portion intersecting the Kalunkudji Fault. As the northern fault continues a north-eastern direction it widens into the Tenke-Fungurume geological formation. The property has access to available infrastructure such as airports, railways, electricity as well as access to the nearby Kando River, providing ample water supply.

Tantalex's new copper/cobalt property is strategically located, as it is surrounded by several large deposits, the most known being Glencore's world-class copper/cobalt open-pit, the Mutanda Mine (also known as Mumi). In 2016, Mumi produced 51,000 tonnes of copper and 6,300 tonnes of cobalt. Its current estimated mine life is 15 years, with 5.5 million tons of copper and 2 million tons of cobalt mineral resources. (Source: www.fleurettegroup.com) Seven kilometers from MUMI is the Kalumbwe Myunga deposit owned by MKM, which hosts reserves estimated at 1.4545Mt at 3.74% Cu and 1.7736Mt at 0.54% Co (November 2011). There is also the Kisanfu copper/cobalt deposit with estimated reserve of 87Mt @ 2.87% Cu and 0.17% Co (2011). Lastly, the Kisanfu-Freeport deposit, located at a similar distance to the Property, has estimated reserves of 108Mt @ 2.62% Cu and 1.08% Co (December 2012).

Dave GAGNON comments on the importance of this acquisition, "This acquisition is a very important and a natural fit for us, as we continue to grow our portfolio of high-tech mineral properties in the Democratic Republic of Congo. The addition of cobalt to our current lithium and tantalum properties will allow us to penetrate the high-tech market, and more specifically, the battery market. This is a highly prospective property located within a stone's throw from many deposit. The synergies we have created with local entities have given way to these important developments, especially since over 60% of current global cobalt supply comes from the DRC."
