The PSUs were granted with a service condition and a performance period of three years. The performance condition will be a function of gold production for the quarter ending December 31, 2021. The number of PSUs that will vest will be the PSUs granted multiplied by a performance multiplier, which will reflect the actual performance in terms of the performance conditions compared to expectations agreed on at the date of grant. RTGS$ On February 20, 2019 the RBZ issued a monetary policy statement, which allows inter-bank trading between RTGS$ and foreign currencies. This changes the exchange rate, previously pegged 1 RTGS$ to the United States Dollar to a fluctuations exchange rate determined by supply and demand. In terms of this new policy, gold producers will continue to receive 55% of its gold proceeds in United States Dollar and the balance will be received in RTGS$ at the prevailing inter-bank rate. Blanket will use the RTGS$ proceeds to settle its local liabilities (wages, taxation, electricity and local procurement) and the United States Dollar component to fund offshore purchases. To the extent that Blanket has surplus RTGS$, these could be exchanged for foreign currency. The changes resulting from the monetary policy statement will not change the primary economic environment in which Blanket Mine operate, however the rate at which monetary items, denominated in RTGS$, are converted to Blanket Mine’s functional currency will fluctuate based on prevailing inter-bank exchange rates.

Gold hedge On January 10, 2019 the Company entered into a hedge in respect of 4,500 ounces of gold per month from February to June 2019. The hedge protects the Company if the gold price falls below $1,250 per ounce and was entered into by the Company for economic hedging purposes to ensure sufficient cash availability for Blanket’s capital investment plan, not as a speculative investment. Indigenisation transaction – Fremiro buy out On November 5, 2018 the Company and Fremiro entered into a sale agreement for Caledonia to purchase Femiro’s 15% shareholding in Blanket. As at the date of approval of these financial statements the transaction remained subject to, amongst other things, approvals from various Zimbabwean regulatory authorities to be effective. In terms of the sale agreement, the Company plans to issue 727,266 shares at $7.15 per share to Fremiro for the cancellation of their facilitation loan which stood at $11,467 as at June 30, 2018 ( $11,468 at September 30, 2018) and the purchase of their 15% shareholding in Blanket, increasing the Company’s total shareholding in Blanket to 64%. The Company will continue to consolidate Blanket in the consolidated financial statements. Eersteling Gold Mining Company Limited On May 31, 2018 the Group entered into a new agreement to amend the initial share sale agreement. The amended share sale agreement allowed for a purchase price of $ 3 million settled through three payments of $1 million payable on the completion date, 12 and 18 months after the completion date. The share sale agreement was suspensive, subject to the conclusion of the rock dump sale (refer note 10 ) and for SH Minerals to obtain funding for the purchase price for the sale. In February 2019 an amount of ZAR13 million ( $1 million) was received as payment towards the purchase price. The payment received in February 2019 effectively transferred the registered and beneficial ownership of Eersteling to SH Minerals and the Group relinquished control.
