The company stated that the sale price included a $2.56m towards interest gained on the purchase price from 1 January 2013 to 4 April 2013.
Also, as per the terms, Alacer will provide toll milling services to process the ore from the Frog’s Leg mine at its Jubilee facility in South Kalgoorlie for about 18 months starting 1 January 2013.
The new terms have been included to replace the initial interim 12 month toll-treatment agreement.
Alacer has declared a $70m special dividend payment to its shareholders of about $0.24 per share.
Commenting on the deal, Alacer, president and CEO David Quinlivan remarked that the company is delighted to pay the first dividend to its stakeholders through the sale of non-core assets.
"We look forward to our ongoing partnership with La Mancha through the toll treatment agreement as we continue to focus on the exploration potential in the South Kalgoorlie district," added Quinlivan.
