DETAILS REGARDING TANTALEX'S PRESS RELEASE DATED SEPTEMBER 14, 2017 ANNOUNCING THE SIGNING OF AN MOU WITH COMINIERE SA FOR THE ASSESSMENT AND DEVELOPMENT OF HIGH TECH MINERAL PROPERTIES (INCLUDING BUT NOT LIMITED TO LITHIUM) IN HIGHLY PROSPECTIVE REGIONS

Following the receipt of a letter from AVZ Minerals Ltd., an Australian Securities Exchange-listed issuer, requesting that Tantalex Resources Corp. review certain terms and information included in its Sept. 14, 2017, press release, Tantalex has signed a memorandum of understanding with La Congolaise d'Exploitation Miniere SA (Cominiere) to exclusively establish, for a period of 75 days, the preliminary terms and financial conditions to evaluate and develop the large land package of highly prospective mining properties, vacant land and hydro power dams. Under the agreement, Cominiere will offer the sizable land package consisting of 35 mining properties (on those that have not yet been awarded) and Tantalex will provide both the financial and technical capabilities to develop the project, which will be more fully defined further to extensive due diligence by the company.

Cominiere is a state-owned company in which 90 per cent of the share capital is owned by the Democratic Republic of the Congo (DRC) and 10 per cent is owned by L'Institut National de Securite Sociale du Congo, the DRC's largest social security and pension fund. Cominiere's portfolio of mining properties cover a total of 12,456 square kilometres, making it one of the largest landowners in the DRC.

Sandstone Worldwide Ltd., a wholly owned subsidiary of Tantalex, is currently engaged in a joint venture with Cominiere (70 per cent Tantalex/30 per cent Cominiere) on its highly prospective Buckell lithium property (comprising PR 12 447 and PR 12 448) located in the Manono-Kitotolo area, a significant land package measuring over 1,000 square kilometres that is contiguous to the Manono-Kitotolo (MK) deposit. In fact, the MK deposit is the geological model upon which Tantalex has also based exploration of its Buckell lithium project. In October, 2016, Tantalex reported the presence of lithium, tantalum, niobium and tin on its Buckell property, based on historical data obtained from Cominere, as well as property assays (see National Instrument 43-101 report issued Jan. 25, 2017). As for AVZ, it is currently engaged in a partnership (or similar type agreement) whereas it holds a 60-per-cent stake in PR 13 359 in the Manono-Kitotolo region. Furthermore, Cominiere and Dathomire Mining Resources SARL, respectively, own a 30-per-cent and 10-per-cent participation (source: AVZ Minerals website).

Tantalex's management strongly believes that, because previous exploration and production from the MK deposit was focused on extracting tin, the deposit, as well as the other surrounding claim blocks, including the Buckell property, have remained untapped in regard to their lithium resources. The company intends to begin an aggressive exploration campaign on the site of the project.

Dave Gagnon, chief executive officer, explained: "This is a transformational moment for Tantalex. We have worked diligently over the last several months to secure the memorandum of understanding and advance the partnership and formally conclude, in the near future, a number of acquisitions, enabling Tantalex to confirm itself as an important player within the lithium sphere. We have an excellent working relationship with Cominiere, and this partnership promises to result in a major shift in direction for our company in terms of access to important land packages, accessibility to infrastructure and support from local government agencies. We are fully committed to finalizing this agreement within the next month."
