Steve Parsons, Managing Director of Gryphon Minerals said “The tenor and extent of the gold mineralisation at the Golden Hill Project, defined by our new low cost geochemical surveys and field mapping, is extremely encouraging.
ASX CODE
The Hounde Belt is one of the most prospective areas in West Africa and our small, skilled and experienced exploration team is quickly and efficiently locating new and exciting high quality prospects. These will be better defined and prioritised for drill testing in the coming months”.

Burkina Faso Earn-In Joint Venture – Golden Hill & Gourma Projects
Gryphon Minerals and Boss Resources Limited (ASX: BOE) completed an agreement to establish a joint venture principally over the Golden Hill and Gourma gold projects located in Burkina Faso, totalling over 1,500 km[2] (refer to ASX announcements dated 05/03/14 and 04/07/14).
Gryphon Minerals is applying proven low-cost exploration techniques to explore the tenure. A review of past work has been completed, new high resolution satellite imagery acquired and processed in-house and relatively high density (>1 sample per ~6 km[2 ] ) drainage sampling, supplemented by laterite sampling, where appropriate, has been completed across all joint venture projects.
This strategy is expected to fast track targeting across the exploration licences as it will direct drilling to those areas most likely to deliver a significant discovery and enable the company to confidently drop ground where appropriate geochemical techniques have been applied and the results are negative.
Golden Hill Project
The Golden Hill project is the most advanced of all the projects in the joint venture and it is considered particularly prospective as it is located within the highly mineralised Hounde Greenstone Belt. This belt hosts the majority of the high grade discovered gold ounces in Burkina Faso, including Semafo’s (TSX, OMF: SMF) recently discovered Siou Deposit (reserves of 769 koz @ 4.94 g/t gold) plus the high grade Yaramoko deposit owned by Roxgold (TSX.V: ROG) (790 koz @ 17.1 g/t Gold). The belt also hosts Semafo’s Mana Mine (6 Moz) and Endeavour Mining’s Vindaloo deposit (TSX: EDV; ASX: EVR); 2Moz @ 2.0 g/t (Figure 1). The Golden Hill project straddles the same structure and stratigraphy that host these high grade deposits.

A number of useful baseline datasets have been collected over the property by Boss Resources and previous explorers, who identified and undertook the initial drill campaigns on some, but not all, of the prospects (refer to ASX announcement dated 05/03/14 for significant past intercepts).
Work by Gryphon Minerals to date includes prospect mapping, rock chip and drainage sampling (50 and 119 samples respectively) and soil sampling (3506 samples) across seven prioritised areas. The results included 28 soil samples exceeding 1g/t Au to a peak of 8.53g/t Au and a further 29 samples between 500 – 1,000 ppb Au. The results have confirmed some of the work completed by the former explorers, whilst also delineating 5 new prospects, namely, Peksou North, Ma West, Didro, Nahirindro and Nabele NE.
BLEG stream sediment sampling has also been completed across the project, collecting samples at an average density of approximately 1 sample per 5 km[2] . This returned some highly anomalous results exceeding 100 ppb Au, compared to a background value of around 2 ppb Au. The tenor of the anomalism is very high adding confidence to the hypothesis that this is significantly mineralised terrain. This high precision multi-element geochemical data compliments the existing datasets and has fulfilled its objectives of allowing the company to confirm where to focus its efforts and where little or no work is warranted.

Gourma Gold Project
The Gourma Project is located within the Fada N'Gourma Greenstone Belt, 250km east of Ouagadougou and only 80 km south, south west of Niger's largest gold deposit, the 50,000 ounce per annum Samira Hill gold mine (1.9 million ounce project). The Project consists of four contiguous permits (Diabatou, Tyara, Foutouri and Boutouanou) that cover a total area of 850 km². It is accessible from the south off the Fada N'GourmaKantchari highway via a well maintained gravel road and from the west via a gravel road from the town of Gayeri.
The Gourma Project covers a highly under-explored sequence of Birimian greenstones that host abundant artisanal workings within strike of extensive regional shear zones.
There are several significant gold targets that are currently being geologically reviewed by the company. The Tambiga Hill prospect contains over 1,000 artisanal pits and shafts up to 60 metres deep that cover an area 500 x 250 metres. This area has never been drilled. At the Diabatou prospect active hard rock and eluvial workings cover an area of 1,600 x 400 metres while at the nearby Gariaga Prospect artisanal workings cover an area of 1,300 x 800 metres.
Work by Gryphon Minerals to date includes detailed BLEG stream sampling and selective lateritic lag sampling in areas deemed appropriate. Multi-element drainage and laterite sample assays are presently being reviewed and interpreted. High resolution (50 cm) satellite imagery has been shot and processed in-house and used to map artisanal gold workings and to identify areas of outcrop. Field mapping and site visits to the workings has been planned, with further mapping and sampling to begin now that the wet season has concluded and field conditions allow access.
Côte d’Ivoire Exploration
The company has two new 400 km[2] tenements covering prospective terrain in North West Côte d’Ivoire. The Odienne Permit straddles the Sassandra Fault close to the margin of the Birimian and Man Shields with a mix of granite and greenstone lithologies which extend north into Southern Mali. A reconnaissance exploration programme consisting of detailed BLEG stream sampling (approximately 1 sample per 4 km[2] ) and reconnaissance geological mapping is in progress with results expected in the first quarter of 2015.
The company has entered into an option to joint venture three permits in Côte d’Ivoire with a local company. Two permits have been granted and these are presently being BLEG stream sampled ahead of any decision to enter into the joint venture.
