De Oliveira is a professional engineer with more than 35 years operational experience in Latin America and West Africa in base metals and gold mines.
He holds qualifications in mining engineering, minerals processing and project management and is currently completing a PhD in Management - Leadership and Organisational Change in the U.S.
Most recently De Oliveira held the position of chief operating officer with CuCo Resources, a private Canadian company with copper and cobalt operations in the Democratic Republic of the Congo.
He has also previously served as general manager of First Quantam Minerals' Frontier Operations in the Democratic Republic of the Congo and the Guelb Moghrein Operations in Mauritania, as well as operations manager at AngloGold Ashanti's (JSE: ANG, NYSE: AU) Sadiola Hill Gold Mine in Mali.
Before moving to Africa in 2005, De Oliveira fulfilled a variety of consulting, mine management and technical engineering roles in the gold and industrial minerals sectors of Venezuela, Uruguay and Brazil.
De Oliveira will take on the responsibility of overseeing Lachlan Star's operations and business development in Latin America including the CMD Gold Mine in Chile, where the company yesterday announced it had delivered its highest level of gold stacked at the mine since it took ownership of the operation.
For the month of April Lachlan Star stacked 6,000 ounces of gold.
A further achievement was the increase in the grade of the stacked ore to 0.61 grams per tonne (g/t), the highest stacked grade since October last year.
Importantly, the increase in stacked gold was achieved despite Lachlan Star not mining for most of the month in the Chisperos and Las Loas pits.
The company is also working to optimise its mining costs by converting part of the CMD Mine operations to owner mining, which is expected to deliver cost savings of US$100 to $150 per gold ounce.
The mining contractors onsite will be rationalised from three contractors down to one which will deliver an immediate saving on mining unit rates.
Lachlan Star has placed an order with Komatsu Chile for a 100 tonne truck fleet and associated equipment, with delivery anticipated towards the end of 2012.
The fleet will be used at the Tres Perlas pit due to an increase in the resource base.
