The consolidation of the shares to make it less 'volatile' will already ensure a drop in the value of your shares. As for historical data, looking at Lonmin the past 8 years, it is clear the company is falling. Lonmin has not fallen suddenly, something from which it can recover, but its fall has been gradual, indications of a company in trouble. In fact, it has fallen so much that there is virtually no more chance for it to recover. No serious investor will invest in Lonmin for the long run.
From what I understand, if the rights shares are bought, they will have enough money to continue for 3 more years?
