Ausdrill's subsidiary African Mining Services (AMS) has secured a mining services contract from Perseus Mining (Ghana).
The agreement requires AMS to provide open pit mining services at Perseus' Edikan gold mine's Eastern Pits operations in Ghana, West Africa for the next three years, starting from the second quarter of this year.
Works are expected to generate close to $223m in revenue over a five-year period.
AMS, which has been providing mining services to Perseus since 2011, will also have an option to extend the contract for two more years.
Ausdrill managing director Ron Sayers said: "We are delighted to extend the relationship we have developed with Perseus in Africa.
"The award of this contract clearly demonstrates the capability of AMS to deliver quality service on schedule."
Edikan gold mine, which was previously known as the Central Ashanti Gold project and Ayanfuri, has 5.25 million ounces (Moz) of measured and indicated gold resources, including reserves of 2.36Moz of gold and 2.17Moz of inferred gold resources.
Perseus Mining also holds 1.4Moz of indicated gold resources, including 0.66Moz of reserves and 0.52Moz of inferred gold resources on its West African projects, Grumesa in Ghana and Tengrela in Côte d'Ivoire.
Diversified mining services company Ausdrill has operations across Australia, Africa and the UK.
