GoldStone is an AIM listed exploration company with exploration skills that focus on gold in West and Central Africa. The company’s projects are located in Ghana, Senegal and Gabon, and range from grassroots to advanced exploration.
The company is constantly reviewing new gold exploration opportunities to further grow its exploration portfolio and to reduce discovery risk. Once acquired, the company's strategy is to develop the projects towards the Bankable Feasibility Stage.
The Homase-Akrokerri licenses are located near AngloGold Ashanti’s Obuasi mine within the well mineralised Ashanti Gold Belt in Ghana where more than seventy million ounces of gold have been discovered. Historical drilling on the license areas by previous explorers resulted in the discovery of gold mineralisation along five kilometres of strike.
The objective of exploration on the Homase-Akrokerri license areas is to find extensions of the known ore body along strike and below the presently known JORC compliant gold resource and to explore an area typified by intense artisanal mining in the Akrokerri license area. Recently the company announced an initial resource for the Akrokerri permit from historical drill data. The combined JORC compliant gold resource for the Homase-Akrokerri project presently is 405,556 ounces at an average grade of 1.42 grams per tonne.
The Manso Amenfi joint venture complements the more advanced Homase-Akrokerri licences in Ghana. First results from a permit wide soil survey yielded several gold in soil anomalies, some of which are in excess of five kilometres long.
The Manso Amenfi License is prospective because it lies along strike of a zone of intense artisanal gold mining and the Ayanfuri gold deposit, where Perseus Mining Limited defined a gold resource of 5.3 Moz. The intersection of the Salman structure, which controlled the formation of Adamus Resources Ltd's Salman gold deposit (2.1 Moz), and the Ayanfuri structure abuts the eastern boundary of the License and will be a priority exploration target. Other exploration targets include the margins of two granitic intrusions which straddle the northern and southern concession boundaries. Similar intrusions are known to have controlled the formation of gold mineralisation elsewhere in the Ashantigold belt.
Sangola Permis de Recherche
In Senegal the company holds the Sangola Permis de Recherche, which has never been explored by modern exploration methods. The area covered by the licence is highly prospective because exploration of the Kenieba Inlier resulted in the discovery of more than 30 million ounces ("Moz") of gold in five major deposits in Mali and Senegal. The Licence contains locations of artisanal gold mining activity and covers the south-western part of the Main Transcurrent Shear Zone (“MTZ”), a major gold bearing system that yielded the recently discovered 3.4 Moz Massawa gold deposit (Randgold Resources Ltd). The Massawa gold project is presently undergoing a feasibility study and most likely will be the second modern gold mine in Senegal after the first gold was poured at Mineral Deposits Limited’s Sabodala gold mine during March 2009. Further to the north the same gold belt is targeted by Mineral Deposits Limited and Bassari Resources Limited. Both companies have located new mineralisation (Sounkounkou and Sanbarabougou) along this 70 km long gold anomalous belt. The Licence covers the very prospective basalts and andesites (Mako Volcanic Formation) that host the 3 Moz Sabodala deposit, presently the only active gold mine in Senegal. Despite its strategic position the Licence is still largely unexplored.
The Oyem and Ngoutou permits in Gabon (Central Africa) were granted during April 2011. Both permits contain robust gold in soil anomalies in excess of 15 kilometres length. Exploration has commenced on both permits.
The Oyem permit contains a 15 km long, robust and east-west trending gold in soil anomaly. This anomaly was detected together with several other anomalies during the period from 2005 to 2009 when 14 million euros of European Union funding was applied by the French, South African and Gabonese Geological Surveys to outline the mineral prospectivity of Gabon. The Oyem permit was “cherry picked” for application when GoldStone’s geologists reviewed the quality of the soil anomalies resulting from the country-wide survey.
The Ngoutou permit contains a robust gold in soil anomaly which is in excess of 15 km long. This anomaly was detected together with several other anomalies during the period from 2005 to 2009 when 14 million Euros of European Union funding was applied in a survey (‘Sysmin Survey’) by the French, South African and Gabonese Geological Surveys to outline the mineral prospectivity of Gabon. The Ngoutou permit was applied for after the area was “cherry picked” from the Sysmin Survey results by GoldStone’s geologists. Many of the streams which drain the anomalous area have been targeted by artisanal gold miners and mining of alluvial gold is the principal source of income of the locals living in three villages on the north-western flank of the gold anomaly.
The gold anomaly coincides with elevated levels of iron, vanadium and tungsten and covers gold-prospective Archean amphibolites. The results of an airborne magnetic survey show that these amphibolites are marked by a magnetic low (blue) and indicate good agreement between the outline of the gold anomaly and the contact between amphibolites and the surrounding rocks. This would point to a model where gold was precipitated from mesothermal solutions at lower crustal levels as a result of neighbouring rock types that differ in competence and chemistry. The magnitude of the soil anomaly together with a plausible geological model make this permit highly prospective.
