1.1.1 Wednesday 15 March 2017SCOTGOLD RESOURCES LIMITED (The "Company" or "Scotgold") 聽 Update to the Cononish Bankable Feasibility Study (BFS) and Short Term Funding Plan 聽 HIGHLIGHTS 路 An update to the Bankable Feasibility Study ("BFS") for the Cononish Gold and Silver Project dated August 2015 has been completed by Bara Consulting Limited, which principally evaluates the economic impact of a range of technical development options and the current economic environment. As a result the "Phased Project" development option has been selected as the most favourable overall, which incorporates the following key changes: o Improved economic returns due to both the change in TSF design and higher assumed gold price of 拢920/oz ($1,150/oz) (previously $1,100/oz). 搂 The peak funding requirement reduced from 拢18.5m to 拢7.4 million; 搂 Life of Mine EBITDA increased from 拢67m to 拢100m 搂 Pre tax NPV (10%) of 拢23m increased to NPV (10%) 拢43m o The development schedule is now designed in two phases. The first phase at 3,000 tonnes per month (tpm), the second phase at 6,000 tpm; o The Tailings Storage Facility (TSF) is now designed using a "Dry Stack" system; 路 A new planning application will be required for the revised development plan and the Company has commenced the "Pre Application Consultation" process with the Loch Lomond and the Trossachs National Park Planning Authority. It is anticipated that the full planning process should be completed by the end of 2017. 路 The Company has been granted an extension to the Bulk Processing Trial (BPT), as previously reported, and it is anticipated that this will continue to contribute to the Company's working capital requirements through 2017. 路 The Company has also agreed a 拢1 million loan facility with its Chairman, Nat le Roux (net approximately 拢0.7m after repayment of the existing 拢0.3m facility currently in place with Nat le Roux) which it is anticipated will provide sufficient working capital for the Company to complete the planning application process and, subject to a positive planning decision, implement a funding plan for the development of Cononish Gold and Silver project commencing in Q1 2018. 聽 UPDATE TO THE BANKABLE FEASIBILITY STUDY 聽 The Company is pleased to announce the results of a recently completed update to the Bankable Feasibility Study, completed in August 2015. We have completed a review of our development strategy and we have, after considering a number of alternative production schedules, selected the Phased Project scenario as the most favourable overall under current economic conditions. While undertaking this work we have also taken advantage of revising the TSF resulting in a more practical, lower capex (albeit a higher opex) and reduced environmental impact dry stack design. This has resulted in a much reduced peak funding requirement. The necessary revisions to the permitting requirements are underway and we expect final permission for underground development work to be granted by Q1 2018. Subject to permitting and securing the necessary finance, we expect to commence work underground in Q2 2018 and to reach a sustainable First Phase 3,000 tpm by early 2019. The Second Phase increase to 6,000 tpm will be self-funded and is scheduled to be achieved by Q3 2021. |

Options Considered in the Update to the BFS
聽
Various scenarios were considered in the update. These included:
1. A revised BFS using an updated gold price.
2. A full scale case based on the BFS but using the modified TSF.
3. A full scale case but also assuming access to a cyanidation plant within Scotland. Note this is the only option which considered cyanidation as opposed to the currently envisaged sulphide concentrate sale.
4. A half scale case processing at 3,000 tpm for the life of the mine.
5. A phased project where build-up to 6,000 tpm is funded from the first phase of 3,000 tpm. The future development of the mine is now based on this scenario.
The table below shows the assumptions used for each scenario:

Technical Comparison of BFS and Phased Project
路 The Resource and Reserve estimates remain as previously published.
路 The mining methodology of Long Hole Open Stoping (LHOS) remains as is;
路 Some minor revision to the development design on the 400 m adit level has been undertaken to reduce initial development requirements;
路 The development scheduled is now designed in two phases. The first phase at 3,000 tonnes per month (tpm), the second phase at 6,000 tpm;
路 The process route remains as is. A simplified basic design will be used for the first phase and the full scale design as per the BFS will be used for the second phase. Whilst elements of the first phase may be reused, this has not been assumed in the capital estimation.
路 The timing of the second phase is assumed to occur after 2.5 years of phase 1 production, once sufficient cashflow reserves have been accumulated and the project can self-fund the required second phase capital.
路 The conventional valley fill TSF in the BFS has been replaced by a "Dry Stack" TSF, comprising 11 individual stacks constructed sequentially over the life of mine. This requires an additional dewatering circuit within the processing plant but obviates the high capex requirement of a TSF impoundment dam and associated civil works. The financial impact of this is therefore an overall reduction of capital but increase in operating cost.
路 The dry stack TSF calls for waste rock throughout the life of mine in the construction of each stack, so waste is no longer required to be stored underground. Whilst some waste may still be stored underground, this provides significantly improved operational flexibility.
路 The dry stack TSF has been designed using landscape architectural consultants to specifically address the environmental impacts which are of concern to the Loch Lomond and the Trossachs National Parks Planning Authority ("LLTNPPA") and has several significant environmental advantages in comparison to the already permitted TSF.

Financial Comparison of BFS and Phased Project
聽
路 Although the TSF capital cost was reduced significantly to 拢404,206, operating cost was increased from 拢327/Au equivalent oz in the BFS to 拢379/Au equivalent oz in the phased approach, as most of the TSF cost is now an on-going operating cost. The total capital cost of the processing plant increased from 拢7.2 million to 拢10.3 million in the phased approach. This was due to the need to install an interim reduced capacity plant for Phase 1. However, we believe that there are further cost savings possible in the final plant which have yet to be identified fully.
路 Total all in cash costs (capital, operating and royalty) per Au equivalent oz is 拢487/oz for the phased approach compared to 拢455/oz for the original BFS.

SHORT TERM LOAN FUNDING PLAN
The Company has entered into a short term loan agreement with Nat le Roux, the Company's major shareholder and non executive Chairman. The key terms of the agreement are as follows:
路 Principal: 拢1,000,000.
路 Term: 1 year from execution (14 March 2017).
路 Interest rate: 10% per annum.
路 Repayment: Principal and interest repayable on expiry of term.
路 Security: A security agreement placing a charge over all the Company's assets is included.
路 Use of Funds: Working capital requirements and the redemption of the existing 拢300,000 loan facility and accrued interest (6% pa) provided by Nat le Roux.
路 Redemption: The Company may elect to redeem the loan at any point during its term without penalty.
The short-term loan agreement with Mr Nat Le Roux constitutes a related party transaction under Rule 13 of the AIM Rules. Accordingly, the board of Scotgold, excluding Nat Le Roux who is precluded from opining, consisting of Richard Gray, David Swan, Christopher Sangster, Philip Jackson and Gabriel Chiappini, having consulted with Stockdale Securities Limited, the Company's nominated adviser, consider that the terms of the Transaction are fair and reasonable insofar as its shareholders are concerned.
聽
Nat le Roux commented "Whilst the Company has a demonstrably viable project in the Cononish Gold Mine, we have struggled since the completion of the BFS in August 2015 to secure a funding package on terms acceptable to shareholders. The revised development plan now completed significantly lowers the financing hurdle and improves the economic returns, with significant further enhancement from the current Pound Sterling price of gold. It does however mean the Company requires further working capital to complete the permitting process and I have therefore agreed to offer a loan facility to the Company as a mechanism to bridge this gap."
聽
Scotgold CEO, Richard Gray said "It is extremely gratifying that we have managed to use the experience of the BPT to re-engineer aspects of Cononish and add significant value. With our improved economic returns and short term funding secured which avoids undue dilution for the existing shareholders, we now look forward to securing an attractive full financing package and subject to permitting, putting our mine into production at the earliest opportunity".
