This drill program focused on testing an extensive, coincident EM and magnetic response from a 2007 airborne geophysical VTEM survey, and a very strong downhole EM anomaly identified after the 2007 drill program.
Thirty-seven (37) holes totalling 8388.4 m have been drilled along a strike length of about 600 m on the Mystery prospect. The first two holes MYS07-001 and 002 were drilled on the prospect in 2007, and the remainder was drilled in 2008. In 2008 Goldbrook successfully outlined a major continuous mineralized zone at the Mystery prospect. Drilling at Mystery appears to confirm a vertical to steeply dipping, mineralized zone varying in thickness from about 10 to 60 m along a strike length of over 175 m. Mineralization extends over 300 m in depth in the vicinity of some sections and remains open to both the east and west of the 2008 drill pattern. Table 1 documents the significant mineralized intervals identified by drilling.
 Drill rig on the Mystery prospect with geologists Jamie Pardy and Sheila Jonnes in the foreground Mystery is hosted within a fine-grained peridotite that occurs as a northeast-southwest trending oblong polygon in the centre of the map area. This unit is displaced in the centre by a northwest to southeast oriented fault. Gossanous zones are mostly confined to the peridotite unit, and the most intense gossan is found in the northern part of the map within an area of rubbly subcrop and float over a strike length of approximately 200 m. The mineralized zone consists of disseminated/interstitial sulphides, net-textured sulphides and massive sulphides comprised largely of pyrrhotite, chalcopyrite, pentlandite +/- pyrite. Continued drilling of the Mystery zone to better define the extent of the sulphide mineralization will be a high priority for the 2009 drilling season.

Drillholes MYS08-001, MYS08-002 and MYS08-003 were the first holes drilled at Mystery during 2008. Both MYS08-001 and MYS08-003 intersected a wide mineralized zone in peridotite, extending far below the mineralization encountered during the 2007 drilling. Mineralization geometry of the peridotite resembles that of section 490775E. In both sections (25 metres apart) the extent of the mineralization remains open to interpretation.  Numerous significant intersections were encountered in section 490775E where mineralization forms a thick subvertical to slightly south dipping zone. This steeply dipping zone appears to be roughly 30 to 40 m in thickness extending over more than 200 m in depth on this section. The upper and northern peridotite is host to the mineralized zone. |
