MRO Millrock Resources Inc

Millrock Resources Inc. (TSX-V: MRO, OTCQB: MLRKF) ("Millrock" or the “Company”) is pleased to announce that partner Resolution Minerals Ltd. (ASX: RML) has reported that thick intervals of intrusion-hosted gold mineralization have been intersected at the Sunrise prospect, 64North gold project. The intervals were intersected in a recent rotary air blast (RAB) drill program that was carried out at the project.

In total, Resolution drilled 27 holes along a fence 1,400 meters in length. The style of mineralization is similar to that observed at the Fort Knox gold mine operated by Kinross near Fairbanks, Alaska. Drilling detected gold over a 280-meter-wide corridor which is open at depth and to the north and south. The host granite intrusion is interpreted to extend more than one kilometer to the south of the recently completed RAB drilling. The gold mineralization is contained within a large gold-in-soil anomaly. The Sunrise prospect is located approximately four kilometers southwest of the Pogo Mine, which is operated by Northern Star Resources Limited.

Drill result highlights include:
Hole 21SU007	36.6 meters at 0.33 g/t gold from surface
	Including:	1.5 meters at 1.42 g/t gold from 1.5 meters depth, and
		1.5 meters at 2.60 g/t gold from 9.1 meters depth.
Hole 21SU009	74.7 meters at 0.26 g/t gold from surface over the entire length of the hole
	Including:	1.5 meters at 1.77 g/t gold from 12.2 meters depth, and
		1.5 meters at 1.02 g/t gold from 48.4 meters.

Of the 27 holes drilled, nine holes intersected gold mineralization grading above a cut-off grade of 0.1 g/t gold over significant intervals. The drill results indicate a mineralized corridor 280 meters in length. There is a strong association of bismuth and arsenic with gold-mineralized rock. This is the same metal association observed at Kinross’ Fort Knox gold mine. A complete listing of results is shown in Table 1A.

Resolution also reports that other potential Fort Knox style intrusive targets have been recognized near the Pogo Mine road, proximal to the Sunrise Prospect. The company plans to make a ground appraisal of the Sunrise Prospect and surrounding prospects in late May. Further drilling and geophysics are under consideration.

Resolution is also planning a 2,000 meter reverse circulation helicopter-supported drilling program on the East Pogo Prospect. The drilling is scheduled to commence in early June. High-grade gold mineralization identified last year during surface work is to be targeted.
