Rubicon Commences Underground Drilling at F2 Zone and Reports New High-Grade Results,
Phoenix Gold Project, Red Lake, Ontario
-1.25 oz/ton gold over 6.6 feet and 3.6 oz/ton gold over 3.3 feet –
-New lower grade hit at 4,714 feet (1437 metres) below surface suggests new depth potential. More deep drilling underway-

Rubicon Minerals Corporation (RMX.TSX: RBY.NYSE-AMEX) is pleased to announce that it has commenced
underground drilling at its Phoenix Gold Project, located in the heart of the prolific Red Lake Gold District of Ontario.
Rehabilitation of existing underground levels is complete and the hoist and shaft have been successfully recommissioned.
Drilling is currently being carried out from the 122 metre (400 foot level) from one drill station and
two additional drill stations will be added over the next month. Underground drilling is currently supplemented by
drilling with three rigs from surface. Shaft sinking to a depth of 350 metres (1148 feet) below surface is targeted to
commence before the end of June to allow for drilling from that level.
During May, diamond drilling was restricted due to ongoing rehabilitation of underground workings and ice break-up.
Nevertheless, new high-grade gold intercepts of 1.25 oz/ton gold over 6.6 feet (42.9 g/t gold over 2.0 metres) and 3.60
oz/ton gold over 3.3 feet (123.5 g/t gold over 1.0 metre) were returned (see Table 1) extending high-grade gold
intercepts to a 700-metre strike length (see Figures 1 and 2 for new assay locations). Also of note is a new deep
intercept of lower grade gold mineralization at a depth of 4,715 feet (1437 metres) below surface, some 1,050 feet (320
metres) deeper than the previous deepest intercept. The new intercept grades 0.10 oz/ton gold over 16.4 feet (3.3 g/t
gold over 5.0 metre) and suggests high potential for additional gold mineralization to depth. To this end Rubicon is
currently drilling two deep master holes to a depth of approximately 1600 metres below surface in Areas 7 and 8 (see
Figure 2). These holes will test the core of the F2 Zone at depth and will be used to wedge off to test shallower levels.
Objectives of Ongoing Drilling
Figure 2 shows the distribution of known gold intercepts within the larger F2 Zone target area (1000 metres x 1800
metres) which is divided into nine target areas. To date, significant drilling (30,192 metres) has been carried out in one
of the nine areas (Area 1) which extends from surface to approximately 550 metres below surface. The intent of the
ongoing 80,000 metre drill program, referred to as the ‘9X program’, is to better understand the size of the system and
to systematically test an additional eight target areas where wide-spaced high-grade intercepts have been intersected to
date as further drilling is clearly warranted.
