The Mt. Boyce project area covers a part of the Kurnalpi greenstone belt in the Eastern Goldfields Superterrane (EGS) in the Yilgarn craton in Western Australia. The EGS is known as one of the most prospective areas of orogenic-type gold mineralization in the world. A total of 71,462 m of Aircore drillings and five diamond drillings have been completed since the Mt. Boyce tenements were granted in November 2015. Greater than 14 km-long gold anomalous zone was identified in the Mt. Remarkable prospect, northern part of the tenement area. The structural interpretation by using core samples of Aircore holes aided in targeting diamond holes. The diamond drilling successfully intersected gold mineralization and revealed valuable geological information under cover, which improved geology model in the Mt. Remarkable area. Further scout drilling program is now ongoing and the results to date well support the model.
