MAY 2009

Margaret Hawke, a 25-year old geologist, drills the discovery RC drill hole at Sandfire’s Doolgunna Project in Western Australia. These drill holes unearthed massive sulphide mineralisation at depth in a region better known for its gold discoveries, leading to one of the most celebrated recent mineral discoveries in Western Australia. The first diamond drill hole targeting the new deposit later returned a stunning intersection of 75m @ 2.4% Cu and 47m @ 5.3% Cu; and 35m @ 6.9% Cu at the DeGrussa deposit.

“Sandfire is one of the Australian mining industry’s most compelling success stories, making the transition from junior explorer to leading mid-tier producer in just over three years…”
JUN 2009 RC drilling confirms the presence of a second, larger zone of mineralisation – “Conductor 1” – immediately north of the initial DeGrussa discovery.
NOV 2009 Discovery of a third high-grade copper-gold deposit at DeGrussa, “Conductor 4”, immediately adjacent to Conductor 1/DeGrussa.
FEB 2010 Phase 1 JORC Compliant Indicated and Inferred Resource of 7.03Mt grading 5.2% copper, 1.9g/t gold and 15g/t silver reported for the DeGrussa and Conductor 1 lenses – less than 8 months after the initial discovery.
JUL 2010 Discovery of Conductor 5 lens at DeGrussa, approximately 900m north-east of the DeGrussa/Conductor 1 deposits.

APR 2011 The maiden blast for the excavation for the “Evans Decline” marks the start of underground development at DeGrussa.
JUN 2011 Positive Definitive Feasibility Study delivered for the DeGrussa Project. The DFS was based on a total mineral resource of 14.33Mt grading 4.6% Cu and 1.6g/t gold for 652,000 tonnes of contained copper and 742,000 ounces of contained gold.
SEP 2011 $380 million project loan facility executed for DeGrussa Project development, led by ANZ Banking Group Ltd.

MAY 2012 First shipment of DSO departs the Port of Geraldton.
OCT 2012 Commissioning of the 1.5 million tonne per annum on-site processing facility commences, with the aim of achieving steady-state nameplate production rates by mid-way through the 2013 calendar year.
OCT 2012 First copper concentrate produced from DeGrussa as part of the commissioning process for the 1.5Mtpa DeGrussa Concentrator.
DEC 2012 Sale of first shipment of copper concentrate from DeGrussa, comprising 5,000 dry tonnes of copper concentrate.
APR 2013 Stage 2 open pit completed, marking the completion of open pit operations and the transition of the DeGrussa Copper Mine to a wholly underground mining operation.
AUG 2013 Official opening of the DeGrussa Copper Mine by Hon. Colin Barnett MLA, Premier of Western Australia and Minister for State Development and Science.
AUG 2013 Sandfire announced a maiden annual net profit after income tax of $88 million for the year ended 30 June 2013, marking its arrival as a successful mid-tier mining company.
AUG 2014 Acquisition of 36% stake in copper developer Tintina Resources (TSX-V: TAU), giving Sandfire exposure to the ongoing evaluation and potential development of the Black Butte Copper Project in central Montana, USA, one of the highest grade undeveloped copper deposits in North America.
AUG 2014 The DeGrussa Copper Mine passed the significant milestone of generating over $1 billion in revenues since the start-up of the operation in 2012. Sandfire declared its first-ever dividend of 10 cents per share for the 2014 financial year.
FEB 2015 Plans announced to construct a 10.6MW solar power station at the DeGrussa Copper Mine, subject to various conditions including final funding. This will be the largest integrated off-grid solar array in Australia, and has the potential to establish DeGrussa as an industry leader in the use of renewable power for mining and processing operations.
JUNE 2015 Diamond drilling at the Monty prospect, which forms part of the area covered by Sandfire's farm-in with Talisman Mining, intersected a significant zone of massive sulphide mineralisation approximately 10km east of the DeGrussa Copper Mine. Assay results from this discovery hole, TLD0004A, returned an excpetional massive sulphide intercept of 16.5 metres grading 18.9% Cu and 2.1g/t Au from 409.5m to 426m down-hole. Step-out drilling immediately commenced at the new discovery to determine the size of the mineralised system and test other target areas within this highly propsective emerging area.
JULY 2015 Construction of the 10.6MW solar power station commenced at the DeGrussa Copper Mine in Western Australia following the signing of final agreements with members of an international consortium formed to finance, construct, commission and operate this state-of-the-art facility.
OCT 2015 Sandfire releases its first Sustainability Report, prepared in accordance with the Global Reporting Initiative G4 framework "core" option.
