He graduated from the Bendigo College of Advanced Education in 1977 with a Bachelor of Applied Science (Metallurgy) and from Latrobe University in 1995 with a Master of Applied Science (Metallurgy). Paul commenced his career as a plant metallurgist with Utah Development Company at their Goonyella mine in the Bowen Basin in 1977, then as plant manager at Gunnedah Coal Company in 1980, before moving to Latrobe University, Bendigo as a research metallurgist in 1989. In 1991 Paul joined Bendigo Gold at the Fosterville mine, which was subsequently taken over by Perseverance Exploration in 1992, where he spent the next 10 years. During this period Paul was instrumental in re-establishing a successful gold heap leach operation and managed the metallurgical testwork program and feasibility study for the development of the Fosterville Sulphide Project to process a refractory gold ore. Following a break from mining Paul was appointed Metallurgy Manager at Bendigo Mining in 2005 and was involved in the design, construction and commissioning of a 600k tpa gold plant utilising gravity, flotation and cyanide leaching to recover gold. A highlight of this plant was the use of a high pressure grinding roll for the third stage of crushing to maximise gravity gold recovery. Upon cessation of operations at Bendigo in 2007 Paul was appointed Process Operations Manager for Simberi Gold Company Pty Ltd who was establishing a gold mine on the island of Simberi in Papua New Guinea. He managed the establishment of the metallurgical department, training of PNG National operators, commissioning and operations for 18 months.

He completed his thesis doctorate in an agreement between the Universidad Mayor de San Andrés, La Paz - Bolivia and ORSTOM an Office of Scientific Investigation of France on the formation of the Andean Mountain range in the central part of Bolivia and later on the origins of the detritic gold in sedimentary formations of the Bolivian Altiplano, an intramontana basin located at 3,700 metres above sea level. For 7 years beginning in 1998 he was the Exploration Geologist in the Kori Kollo mine, then-owned by Battle Mountain Gold Co. USA and recently owned by Newmont Gold Co.

Later on he was selected by Battle Mountain Gold to carry out exploration in Argentina in auriferous projects located in Pre-Cambrian terrains of the Mendoza and San Juan counties. He also explored in the Patagonia county of Santa Cruz, with occurrences of epithermal gold deposits hosted in Jurassic piroclastic sequences like Cerro Vanguardia, owned by Anglo Gold (3.7 M Oz Au - mineral resources). He was later selected to open the exploration office in Lima - Peru where he worked for two years. It was here that Herbert participated in the auction of important mining centres of the State with mineralisation of gold and base metals, carrying out the corresponding due diligences. In 2008 he was Chief Geologist in the San Cristobal open pit mine owned by APEX Silver Mines Ltd., a world class epithermal deposit of Zn, Pb – Ag. The initial mineral content was of 450 million ounces of silver, 8 billion pounds of zinc and 3 billion pounds of lead contained in 231 million tonnes of open-pittable proven and probable reserves. Based on his experience he presented diverse technical works in National and International Congresses (Bolivia and Chile) about Structural Geology, Tectonic, Sedimentation and mesothermal – epithermal mineralization in different type of host rocks.

Variations of commodities studied were diamonds at Bow River and nickel whilst in the Forrestania Greenstone belt. A move in 1997 saw deep exploration develop at the Fosterville Gold Mine in Victoria where mine site exploration extended the life of the Perseverance heap leach operations and delineation of sulphide underground resource eventually seeing the project through feasibility to mining of the BIOX bacteria extraction process to build the company through to its successful open cut and underground sulphide operations. Trevor joined Republic Gold in 2006 as Exploration Manager to maintain, manage and explore Republic's significant prospective tenement holdings in Far North Queensland. |
