After obtaining interests in the project in 2002, please also see History, Pacific Iron Ore's predecessor company, Emerald Fields, conducted a substantial exploration program on the Pearson Project in 2003-2007. It began with geochemical, geological and geophysical work, including sediment sampling, and ground magnetometer surveying. Drilling began in April 2004, with seven diamond drill holes in the Reko deposit. Concurrently Emerald Fields staked additional claims to fill out the Pearson Project holdings.
A further seven drill holes followed in April-May 2005. These confirmed the locations of the Daniel and Conqueror ore bodies discovered previously, validated the significance of the deposit. The drilling returned numerous core samples with iron concentrations of greater than 50 percent over extended pay thickness in several cases exceeding 20 metres. Drilling core was independently analyzed by ALS Chemex, an accredited mineral laboratory, in North Vancouver, B.C., using recognized methods. The lab report is appended to the technical report.
The main exploration activities in 2003-2007 were:
- Review of previous exploration and historical documents;
- Geochemical and geophysical surveying;
- Drilling diamond core holes, many of which intersected magnetite;
- Limited physical site preparation (construction and repair of roads);
- Aerial magnetic survey; and
- Bulk sampling and independent analysis of materials.
These activities culminated in a technical report by an independent third-party professional geologist that met the stringent technical standards of N.I. 43-101. The report was entitled "Technical Report - Geological Summary, Pearson Project, British Columbia", and was prepared by George Owsiacki, P.Geo.
During 2007 and the first half of 2008, Emerald Fields conducted numerous ground magnetometer surveys, rock-sampled and prospected in the Bugaboo, Edinburgh and Granite areas, towards a systematic diamond drill program. In June 2008, after raising sufficient funds for its exploration program, Pacific Iron Ore Corporation commenced its 2008 Exploration Program.
