BEINN UDLAIDH

AQ drilling results

Following identification of significant breccia-hosted gold-silver mineralisation at the Company's Beinn Udlaidh prospect, located five kilometres north northwest of its 100% owned high grade Cononish Gold and Silver Project, Scotgold undertook a drilling programme during the last quarter of 2009 to test a number of the identified breccia pipes.

The Company drilled seven short AQ holes into six of the nineteen breccia pipes identified to date. Assay results are shown in Table 1, and drill statistics are shown in Appendix A.

The initial 'discovery hole' BEBULB1 into pipe BU1 is also included in Table 1 for reference.

'Discovery Hole'

 

Table 1: Summary and analysis of recent AQ drilling results at Beinn Udlaidh

Scotgold considers the high number of anomalous values (>0.1g/t Au) in five of the most recent holes within the short (in relation to pipe size) interval sampled to be highly encouraging especially given the high grade rock and boulders samples discovered nearby (up to 359 g/t gold and 2,520 g/t silver), the limited drilling and the number of other breccia bodies in the area which have had no drill testing or sampling,.

It should be noted that these are narrow (2.7 cm diameter) short holes and have been drilled into potentially large mineralised bodies.  As such, they are testing limited portions of large structures which are often known to show zonation in mineralisation in both horizontal and vertical extents.

Exploration Target Potential at Beinn Udlaidh

Scotgold has confirmed an Exploration Target at Beinn Udlaidh of between 0.57 and 5.7 Mt at a grade of between 1 and 2 g/t Au.

Limited drilling to date at the Beinn Udlaidh breccia pipefield has confirmed anomalous gold grades.  Economic gold grades encountered in breccia hosted mineralisation may lie in the range of 1.0g/t to 2.0g/t based on similar style occurrences elsewhere in the world. Breccia hosted mineralisation may show zonation and include higher grade zones.

The basis for the tonnage potential is the current mapped area of individual pipe outcrops to a depth of between 10m (observed / drilled) to 100m, using a specific gravity of 2.65 and a 'complexity factor' of 70%. It is noted that breccia pipes can extend to depths greater than 100m.

Investors should note that the potential quantity and grade of the Exploration Target is conceptual in nature, there has been insufficient exploration to define a Mineral Resource and it is uncertain if further exploration will result in the determination of a Mineral Resource.

CONONISH Infill / Eastern Extension Drilling Results

Scotgold resumed drilling at the Cononish Gold and Silver Project in Scotland in October 2009.

The objectives of the programme are to:

·           infill a portion of the existing Inferred Mineral Resource at Cononish as a part of the Company's ongoing programme to advance the project to production; and

·           test high grade gold targets (up to 119.9g/t gold) which lie within the recently identified eastern extension of the Cononish mineralisation and outside the envelope of the previously existing Mineral Resource.

The drilling programme also targets mineralisation outside the previously defined resource envelope, specifically the potential down dip continuation of the mineralisation encountered in trenches (up to 16.12 g/t Au over 2.10 metres), surface drill holes (up to 73.10 g/t Au over 1.77 metres) and underground holes (up to 12.35 g/t Au over 1.49 metres).

A programme of 12 short AQ size diamond drill holes are planned from within the Cononish adit to test for possible extensions to the identified mineralisation in the eastern part of the adit outside the existing resource, in particular a 1.6 metre-wide quartz vein where high grades (up to 119.9 g/t gold and 97.2g/t silver) have been reported from historic assays and also possible 'off adit' intersections on the Cononish vein.

Results from four holes, Hole 09 - 01 (resource infill), holes EA - 01, EA - 02 and UG EA 03 (potential resource extension) have been received and are shown in the table below. Drill hole statistics are shown in Appendix B.

All distances are measured in metres.

·     Infill drilling into Inferred Resource:

Hole 09 - 01 was drilled into the existing Inferred Resource on the eastern side of the mine.

·     Potential Resource Extension Drilling - 'Eastern Extension'

Hole EA 01 was drilled into the recently announced 'eastern extension' to intersect the vein 30m below drillhole UG 89 - 04.

Hole EA 02 was drilled approximately 30m down dip of hole EA 01.

Hole EA UG 03 was drilled to intersect the possible strike extension of the high grade vein encountered near the adit entrance.

Scotgold views the results in the eastern extension holes as particularly encouraging and indicating the existence of a further possible significant payshoot which support Scotgold's opinion that the eastern extension may host significant additional resources.

RESOURCE UPDATE

As a result of further investigations and exploration by Scotgold during 2008 - 2009, Snowden Mining Industry Consultants Ltd ('Snowden') was asked to undertake an update on the Cononish resource.

The revised resource estimate for Cononish is shown below and gives a total metal inventory of 163,000 oz Au and 596,000 oz Ag.

Cononish Main Vein Gold Mineral Resources (reported at a 3.5 g/t Au cut-off).

Reported using the 2004 JORC Code (JORC, 2004). Tonnages and contained ounces rounded to the nearest 1,000 t or 1,000 oz. Grade rounded to the nearest 0.1 g/t Au. The Inferred Resource grade is reported with a grade range to indicate the likely upside due to the information effect.

Snowden notes that there is resource potential in the eastern adit zone and that the estimation of additional Mineral Resources is likely once further drilling is complete.

Snowden has previously noted "based on our experience of the Cononish vein system, we believe that there is an Exploration Target around the mine of between 0.5 Mt to 1.0 Mt at a grade of between 10 g/t Au to 15 g/t Au for up to 320,000 oz Au. Much of this potential is based on the along strike and down dip extensions of the Cononish vein, but there are indications that other reefs are present in the area too. At this stage, such figures are highly conceptual and there is no guarantee that further exploration will define additional resources."

PLANNING APPLICATION FOR CONONISH MINE

Following detailed re-assessment of the Cononish project and its environmental impacts carried out in the second half of 2009, Scotgold lodged its application for revision and extension to the current planning application on 25 January 2010. The application was subsequently validated and accepted and the parties signed a non-legally binding processing agreement which indicates a decision date of 7 June 2010, with final notices shortly thereafter. The Company continues to work closely with all relevant agencies to ensure that any concerns that are raised prior to the decision date are addressed to the satisfaction of all parties.

The application was prepared with the assistance of Scotgold's planning and environmental consultants, Dalgleish Associates. Dalgleish Associates is a well established consultancy based in Scotland, specialising in resource (minerals and renewable energy) projects in the United Kingdom with considerable expertise in the Scottish system.

Specialised technical input regarding the application was provided by Scotgold's tailings consultants AMEC Earth and Environmental (UK), Cantab Consulting, Vibrock Ltd (ground vibration and noise consultants) and Rathmell (archaeological studies).

The application envisages a development along the same scales as previously proposed, including the establishment of an underground mine with associated processing and tailings management facilities and infrastructure associated with the project and concurrent restoration of the site. Scotgold believes the application to contain many improvements to the previously permitted development and to be in line with currently accepted 'best practice'. 

As part of the pre-application consultation process under Scottish planning law, the Company subsequently held three 'public' meetings. A presentation was made to the local Community Council and Strathfillan Community Development Trust and two public 'open days' were held in Tyndrum, which is the nearest town to the proposed mine and the Company would like to thank the local community for their ongoing support for the application.

The Company continues to update its technical and financial studies relating to the Cononish project development in order to be in a position to make a production decision post planning.

AIM ADMISSION

The Company's ordinary share capital was admitted to trading on the AIM Market of the London Stock Exchange ("AIM") under TIDM code SGZ on 24 February 2010.

Scotgold's share capital has been listed on the Australian Stock Exchange since January 2008 where it has traded under the same market code, SGZ.

In conjunction with the AIM admission, the Company raised approximately £704,000  (AUD1.2 million)  before expenses through a placing of 15,300,000 new Ordinary Shares at 4.6 pence per ordinary share (the "Placing").  The total number of ordinary shares in issue on commencement of trading on AIM was 117,306,762.  Westhouse Securities Limited is acting as the Company's AIM nominated adviser and broker.

The net proceeds of the Placing are being used by the Company to progress the development towards production of its high grade Cononish Gold and Silver Project and continue its exploration programmeon a number of identified targets surrounding Cononish and across its wider licence area.
