The deal gives Anglo the UK's biggest mining project in a generation and marks its comeback to the fertilizer sector.

It takes the company a step closer to the construction phase of Colluli and then into production in 2022.

The hedge fund said it would vote against Anglo's offer.

Last updated in 2003, the fresh set of principles respond to increased pressure for miners to carry out socially-responsible investments and operations.

The fertilizer company evaluated over the past week a plan to raise $680 million put forward by a consortium of financial investors, but talks didn’t go anywhere.

The company has set up a shareholder helpline to guide tens of thousands of individual investors who bet on the Woodsmith fertilizer project.

The mining giant says its most inclusive and diverse teams have 67% fewer recordable injuries, 28% lower unplanned absence rates and up to 11% higher planned and scheduled work delivery.

Deloitte’s “Tracking the Trends” annual mining report, warns mining leaders they will have to work this year on building trust with communities, consumers and investors.

Colluli has the potential to produce 944,000 tonnes of sop, a premium grade fertilizer, over its 200-year plus mine-life.
