Lara Exploration (TSXV:LRA) has announced an initial resource estimate for mineralization at its Maravaia copper-gold deposit at its Curionopolis exploration license in northern Brazil.
As quoted in the press release:

Indicated resources were estimated for the Osmar Target at 2.14 million tonnes with average grades of 4.2% copper and 0.66 parts per million (“ppm”) gold. Inferred resources were estimated for the Galpão Target at 0.38 million tonnes, with average grades of 3.16% copper and 0.69 ppm gold.

Key parameters included:

• The Osmar indicated resource is based on data from sixteen drill holes (2,565.7 metres in total) completed between 2009-2014, on a grid spacing of approximately 25 metres. The geology was modeled on eight 25 metre-spaced East-West sections through the mineralization. The resource model was then constructed in Gemcom Surpac software with 12.5 x 12.5 x 4.5 metre blocks, 3.125 x 3.125 x 1.125 metre sub-blocks, using a cut-off grade of 0.75% copper;
• The Galpão inferred resource is based on four drill holes (334.45 metres in total) spaced between 30 and 48 metres along a single north-south section through the mineralization;
