Tratramarina - Exploration Summary

Explorer
Work undertaken
Key findings
Fugro
2004 - 2006
Identified multiple magnetic anomalies that could host iron mineralisation.
World bank funded airborne magnetic and radiometric survey with 500m line spacing.
IPR
2012 - 2014
The iron rich horizons are magnetite banded iron formations with a 2.5km strike length and 1km width at surface.

Rock chip samples of outcrop and sub crop averaged 40% Fe, 38.7% SiO2, 0.34% Al2O3 and 0.22% P.

Seven diamond drill holes that tested outcropping magnetite BIF at depth intersected significant mineralisation (see table below). However the geology is complex and some of the drill intersections may not represent the true widths.
IPR have shown the presence of potentially, economically significant magnetite iron ore at Tratramarina.
Wardell Armstrong
Interpretation of geophysical survey, geological mapping, rock chip sampling (305 samples) and seven diamond drill holes for 1,360m.
The grade is as yet, not known with any degree of certainty and the tonnage remains to be defined. However, it may be considered an exploration target with some merit.
International
2017
Reviewed the previous work, undertook a site visit and compiled the Competent Person Report in May 2017.
