The foregoing list is not exhaustive, and there may be additional risks that CPTK, Mkango, or MKAR presently do not know or that they currently believe are immaterial. You should carefully consider the foregoing factors, any other factors discussed in this news release and the other risks and uncertainties described in CPTK's or MKAR's filings with the SEC from time to time, Mkango's filings on SEDAR+, and the risks described in the Form F-4, which include a proxy statement/prospectus.

Any corrections or revisions and other important assumptions and factors that could cause actual results to differ materially from forward-looking statements, including discussions of significant risk factors, may appear, up to the consummation of the Proposed Business Combination, in CPTK's or MKAR's public filings with the SEC, which are or will be (as appropriate) accessible at www.sec.gov, or Mkango's public filings on SEDAR+, which you are advised to review carefully.
