The company is offering $650 million of 10-year notes with a fixed rate coupon of 3.25% per annum, and $500 million of 30-year noted with a fixed rate coupon of 4.2% per annum.
The proceeds will be used to repurchase up to $1.15 billion of existing near-term corporate bond maturities.
Newcrest initiated cash tender offers for any and all of its outstanding 4.45% notes due in 2021 and up to $400 million of its 4.2% notes due in 2022.
"I am pleased with the very strong demand for Newcrest credit which has enabled us to secure long-term debt at coupons much lower than that on our existing corporate bonds," Newcrest managing director Sandeep Biswas said.
"This has allowed us to restructure and extend our debt maturity profile to better match our long asset life."
Earlier this week, Newcrest completed a A$1 billion placement at $25.60 per share to fund the US$460 million of Lundin Gold's debt and streaming facilities, as well as future growth.
A share purchase to raise up to A$100 million was launched yesterday.
Newcrest shares were up 0.9% to $28.09. Both RBC Capital Markets and JP Morgan have $26 price targets.
