Alchemy holds six projects in the Murchison District of Western Australia covering highly prospective areas within the gold endowed yet under explored Murchison Province. Alchemy is actively exploring for lode-gold mineralisation within the ‘golden triangle’ region between Cue, Meekatharra and the Big Bell gold mine, which has been a major gold producing province in the past with gold production in the order of 8 million ounces from mines such as Bluebird, Reedy, Paddy’s Flat, Big Bell, Cuddingwarra, Caledonian, Golden Crown and Great Fingall.

A large portion of Alchemy’s Murchison Projects lie under thick soil cover and historic exploration in the area has left gold targets untested with huge scope to explore using modern exploration techniques and an integrated multidisciplinary approach. Alchemy is focussed on utilising innovative exploration techniques and has developed a 3D model of the subsurface geology over the entire Murchison region and has collected and evaluated multi-element soil and rock chip assays and mineral spectral data using a portable spectrometer. This has facilitated exploration for gold mineralisation in areas of thick soil cover and has equipped Alchemy with an increased opportunity for a major discovery.

Alchemy’s Projects are located within the Murchison Domain of the Archean Yilgarn Craton of Western Australia. The Murchison Domain displays a dome and keel geometry in which narrow greenstone belts of metamorphosed mafic, ultramafic, sedimentary and volcanic rocks occur as structural troughs wedged between broad dome-shaped granitic bodies. The development of the Murchison Domain suite of rocks or stratigraphy involved at least three main geological cycles of volcanism, plutonism and sedimentation from 2820 to 2720 Ma (millions of years ago) and granitic magmatism from about 2785 to 2600 Ma. Layered mafic-ultramafic intrusive rocks constitute nearly half of the greenstone belts. The Project areas cover parts of the Meekatharra-Wydgee, Weld Range, and Abbotts greenstone belts.

The Murchison Domain is structurally complex and has experienced several phases of deformation. The area is dominated by north plunging folds, north striking foliations, north-northwest striking high-strain zones and north-east striking shear zones which overprint early easterly striking folds. The formation of the early folds appears to have resulted from the sinking of the greenstones into the surrounding granitic rocks between 2720 and 2660 Ma. The formation of upright north to north-northeast trending folds and associated structures is related to a craton scale regional east-west compressional deformation between 2660-2630 Ma. The bulk of gold deposits in the Murchison Province (Big Bell, Reedy’s, Golden Crown etc) are associated with the structures formed during the regional compressional event. Several large regional-scale shear zones traverse the Project areas including the Meekatharra-Mount Magnet Shear Zone, Chunderloo Shear Zone and Big Bell Shear Zone. Second order faults splay off the regional shear zones and represent prospective gold bearing fluid pathways and trap sites for gold mineralisation within Alchemy’s Project areas.

Alchemy’s geologists are actively exploring its six Project areas in the Murchison for the next big gold deposit.
