Highlights
• Group gold production for Q2 was 60,976 ounces
• Increased ore mined at Gwalia offset by delays accessing high grade stopes to next quarter, resulting in lower
grade development ore being processed
• Atlantic and Simberi production stable, in line with expectations
• Group AISC1
for Q2 of $2,666 per ounce
• Lower production from Gwalia did not sufficiently offset fixed costs
• Atlantic and Simberi costs in line with expectations
• Merger announced with Genesis to form Hoover House, and demerger of St Barbara’s non-Leonora assets to
form Phoenician Metals
• Reset of St Barbara’s strategic direction
• Zoroastrian development suspended in expectation of nearby Genesis’ ore supplies in FY24
• Strategic review completed at Simberi, with oxide mine life now extended through FY25 and Final Investment
Decision on the Sulphide Project deferred while resource extension drilling is completed in FY24
• Atlantic development focus shifted to Fifteen Mile Stream, as permitting of Beaver Dam paused to allow
further discussions with First Nation groups and other stakeholders
• On track to reach bottom end of Group production and therefore top end of cost guidance.
Managing Director and CEO Dan Lougher said “It has been a disappointing quarter at Leonora as we reset the
operations with a new General Manager, who is setting the site up for improved performance over the next six
months. Simberi had a strong quarter, with its first positive cashflow in five quarters, while Atlantic recovered from
Hurricane Fiona which pushed some production into the third quarter.”
“St Barbara faces an exciting future, following the announcement of the merger of our Leonora operations with
Genesis to form the new Hoover House, together with the demerger of Atlantic and Simberi to create Phoenician
Metals. I believe that this will deliver the best pathway forward for our shareholders by helping to unlock the market
value of Atlantic and Simberi, while driving the consolidation of the Leonora region.”
St Barbara produced 60,976 ounces of gold in Q2 FY23 at an increased AISC of $2,666 due to lower production
compared to the prior quarter. While Simberi and Atlantic performed in line with expectations, the group production
result was lower than anticipated due to delays in accessing high grade stopes at Gwalia, resulting in lower grade
development ore being processed there. With access to high grade stopes since achieved after the end of the
quarter, St Barbara remains on track to deliver towards the lower end of production guidance and the higher end of
AISC guidance for FY23.
