After the company, Sunshine Mines Limited, was issued with a certificate of incorporation it went on further to secure a certificate to commence business in accordance with the laws of Zimbabwe.A prospectus was issued shortly after incorporation inviting members of the public to subscribe for shares in the company. The prospectus which listed John Brown and his four associates as the directors of the company stated that the company had discovered vast deposits of platinum in the Bikita district. As a result of these claims shares in the company started trading at $10 a share and Innocent Mupfumi bought 10,000 shares through a stockbrocking firm.It now transpires that the company discovered deposits of iron ore and not platinum.
