Established in 2016, MAUVIC Pte Limited leverages a Class 1 – Special Quarry Lease from the iTaukei Land Trust, covering an area of 10.24 hectares. The lease commenced on January 26, 2017, with a 25-year term and an option to extend for another 25 years. The quarry’s strategic location next to a waterway enables efficient transportation of rock via barge, reducing environmental impact and transportation costs.
The Mau Quarry has abundance of large Andesite Rock; Andesite is the premium rock used for construction. The demand for quality crushed rock in Fiji is extremely high at present and is expected to remain this way for many years. There are several large projects in Fiji, including roads, airports and buildings, these projects require large amounts of cement, the major suppliers of this cement have confirmed their intent in purchasing crushed Andesite Rock crushed from Mauvic. This significant partnership between Mauvic and the people of the Drekeniwai Tribe will secure for the local people and the stakeholders of Mauvic.
The mining of crushed rock will provide much needed employment opportunities and investment into other opportunities in the area such as farming, export and tourism. MAUVIC Pte Limited operates a quarry in the Namosi area of Fiji, capable of producing 5,000 to 10,000 cubic meters of boulders and crushed rock per month. The quarry has a lifespan of over 50 years at these production volumes, providing a long-term supply of high-quality andesite hornblende rock for construction and civil engineering projects.
Andesite is a grey to black volcanic rock with between about 52 and 63 weight percent silica (SiO2). Andesites contain crystals composed primarily of plagioclase feldspar and one or more of the minerals pyroxenes (clinopyroxene and orthopyroxene) and lesser amounts of hornblende. Andesite is an extrusive igneous, volcanic rock, of intermediate composition, with aphanitic to porphyritic texture. In a general sense, it is the intermediate type between basalt and dacite, and ranges from 57 to 63% silicon dioxide (SiO2).
The mineral assemblage is typically dominated by plagioclase plus pyroxene and/or hornblende. Magnetite, zircon, apatite, ilmenite, biotite, and garnet are common accessory minerals. Alkali feldspar may be present in minor amounts. The quartz-feldspar abundances in andesite and other volcanic rocks are illustrated in QAPF diagrams. Classification of andesites may be refined according to the most abundant phenocryst.
Example: hornblende-phyric andesite, if hornblende is the principal accessory mineral. Andesite can be considered as the extrusive equivalent of plutonic diorite. Characteristic of subduction zones, andesite represents the dominant rock type in island arcs. The average composition of the continental crust is andesitic. Along with basalts they are a major component of the Martian crust. The name andesite is derived from the Andes Mountain range.
The Fiji Islands are situated on a prominent offset of the convergent plate boundary between the Pacific and Australian tectonic plates which marks a broad zone of diffuse spreading and transform faulting, (Begg et al.). Fiji’s main island, Viti Levu, is composed of a sequence of Late Eocene to Recent volcanic, sedimentary, and intrusive rocks that developed due to volcanic activity related to this complex convergent plate margin setting, with most deposited in the Miocene to
Pliocene age.
Local Geology The rocks of the Mau area are grouped under the Mendrausuthu Andesitic Group with the Veisari Sandstone consisting of Andesite-derived sandstone and minor conglomerate being of Late Miocene to Pliocene age with intrusive volcanic rocks of Pliocene age. Veisari Sandstone is the lowermost formation (Band 1968) and is approximately 400m thick consisting mainly of marine siltstone and fine-grained sandstone deposited in water depths of 300 – 500m (Rodda 1982). Site Geology According to the Geological Survey of Fiji, 1:500,000 Series, G.S. 380, the subject site consists of intrusive Andesite rocks of Pliocene age underlain by the Veisari Sandstone comprising andesite derived sandstone and minor conglomerate. The investigation confirmed the expected geology
Mauvic have completed various tests over the past 8 years, including 2 core drill tests at the top bench and base of the site.
Tests have been completed by Entec, Opus and Fiji roads, results have indicated our rock is suitable for both crushed material and boulders for bridges and seawall projects.
Mauvic has developed a strong reputation and genuine approach to adhering to all compliance and Government regulations.
The management team at Mauvic, in consultation with the Mataqali have agreed to ongoing planning and management of the Quarry to ensure all current and future production is in accordance with the granted Quarry Operational Environmental Management Plan and in the best interest of all stakeholders.
