With resources totaling 16.3 million tonnes grading an average 0.72% nickel and 0.33% copper using an 0.5% cut-off, Corazon has come up with a 20% increase in the "measured" category to 3.3Mt at 0.67% nickel and 0.32% copper after assessment of the EL, N, and O deposits.

The Lynn Lake resource is within six deposits, with Corazon upgrading the resources as part of its assessing of the mining potential of the project.

Meanwhile, exploration drilling is underway testing "off-hole" EM conductors defined earlier this year at the Fraser Lake Complex (FLC), about 10km south of Lynn Lake.

The program will consist of about 2000 metres of diamond core drilling, with about 1000m of the drilling to initially focus on three priority targets in close proximity to each other.

Finding resources with better grade would be a big positive.

Corazon has had Lynn Lake on its hands since 2010.

The company raised A$2.6 million last month issuing new shares priced at 3.2c each.

Shares in Corazon were down 7.5% to 3.7c in afternoon trade, capitalising the company at $9.4 million.
