What's lit the fire under the Brockman Mining share price? Let's take a look.

Farm-in and joint venture agreement

Today, Brockman Mining announced its farm-in and joint venture agreement with Mineral Resources Ltd (ASX: MIN) has come to fruition.

The deal was first announced in 2018, but today's news is that the companies are finally signing the joint venture portion of the agreement. 

The deal is between subsidiaries of both companies. Brockman's Brockman Iron and Mineral Resources' Polaris are representing their ASX-listed parent companies.

Originally, the deal would have seen Polaris securing 50% of Brockman's Marillana Iron Ore Project. Today, it's been updated to also include Brockman's Ophthalmia Project.

Under the agreement's terms, Polaris began a farm-in venture at Brockman's Marillana Iron Ore Project. Once Polaris had met its farm-in obligations, the companies would form a joint venture, each owning half of the Marillana Project.

The farm-in agreement's obligations include Polaris providing Brockman with a $10 million loan, spending $250,000 to explore and develop Marillana, and completing a mine site plan.

There's also an agreement that another subsidiary of Mineral Resources would pay for and build a rail and port system from the project to Port Hedland ­– a distance of around 270 kilometres.

According to Mineral Resources, the project will mine iron ore to be sold in China.
