Firestone Diamonds plc ("Firestone" or the "Company"), the AIM-quoted diamond company, is pleased to announce that at the Company's General Meeting, held earlier today, all the resolutions proposed (the "Resolutions") were duly passed.

On 1 December 2017, the Company announced that it had conditionally raised gross proceeds of £18.5 million (US$25 million) through a proposed issue of 147,888,528 Firm Placing Shares and 36,954,356 Placing Shares at an issue price of 10 pence per share. In addition, the Company announced that the 36,954,356 Placing Shares would be subject to clawback through an Open Offer in order to provide Qualifying Shareholders with an opportunity to participate in the Fundraising at the Issue Price.

The Open Offer closed for acceptances at 11.00 a.m. on 19 December 2017 in accordance with its terms. The Company has received valid acceptances under the Open Offer in respect of 9,172,358 Open Offer Shares pursuant to Qualifying Shareholders' Open Offer Entitlements and a further 1,787,192 Open Offer Shares pursuant to Excess Open Offer Entitlements. A total of 10,959,550 Open Offer Shares, representing approximately 29.66% of the total Open Offer Shares available pursuant to the Open Offer, will therefore be issued to Qualifying Shareholders and will provide the Company with gross proceeds of approximately £1.1 million through the Open Offer. Qualifying Shareholders who validly applied for Open Offer Shares pursuant to their Open Offer Entitlement will receive the full amount of Open Offer Shares they applied for and will also receive the full amount of the Open Offer Shares applied for under the Excess Application Facility.

The remaining 25,994,806 Open Offer Shares not applied for by Qualifying Shareholders under the Open Offer will be taken up by Placees under the terms of the Placing.

As also announced on 1 December 2017, the following Directors are subscribing for New Ordinary Shares at the Issue Price pursuant to the Fundraising.

Following Admission, the Company's total issued share capital will comprise 505,113,970 Ordinary Shares and this figure may be used by Shareholders as the denominator for the calculations by which they will determine if they are required to notify their interest in, or a change to, their interest in the Company under the Disclosure Guidance and Transparency Rules of the Financial Conduct Authority.
