The people behind GUMA.
GUMA is 100% Indigenous-owned and operated, led by a Nyiyaparli Traditional Owner and a managing director committed to creating opportunity through excellence in civil and mining services.

Raymond Drage
Raymond Drage is a Nyiyaparli Traditional Owner and the founding Director of GUMA. A respected Elder and businessman, Raymond has a deep knowledge of the Traditional Owner groups of the East Pilbara and has spent decades advocating for the protection of Country and heritage.
Raymond co-founded GUMA in 2012 alongside Michael Stream and Victor Parker, with a vision to create a mining services company that would deliver economic opportunity back to Indigenous communities. His leadership has been instrumental in establishing GUMA as a trusted partner to major resource companies across the Pilbara.
Raymond's connection to the land is deeply personal. Every project GUMA undertakes is, for him, a way to honour his ancestors and contribute to the growth and empowerment of the Nyiyaparli people. He serves as a bridge between Indigenous heritage and the demands of the modern mining industry — ensuring that cultural respect is woven into every aspect of operations.
Mathew Cook
Mathew Cook is the Managing Director of GUMA Pty Ltd, bringing financial expertise and an extensive, wide-ranging background in business across Western Australia.
