Rockhaven Resources Ltd. (TSX VENTURE:RK) ("Rockhaven") is pleased to announce
results for five additional drill holes from the 2014 program at its 100%-owned
Klaza property located in the Dawson Range Gold Belt of southern Yukon.
The 12,000 m diamond drill program is focused on delineating and expanding areas
of high-grade gold and silver mineralization within multiple structural zones
that have been identified on the property.
Highlights from the new drill holes testing the Western BRX Zone are as follows:
-- 26.80 g/t gold and 705 g/t silver (40.90 g/t gold EQ(i)) over 0.84 m and
29.30 g/t gold and 36.8 g/t silver (30.04 g/t gold EQ) over 1.01 m -
Hole 144
-- 10.79 g/t gold and 121 g/t silver (13.21 g/t gold EQ) over 2.90 m - Hole
145
-- 15.95 g/t gold and 123 g/t silver (18.41 g/t gold EQ) over 1.89 m - Hole

"These new high-grade intercepts provide further confirmation of the excellent
continuity and size potential of the Western BRX Zone," stated Matt Turner, CEO
of Rockhaven Resources. "Systematic drilling continues within the Western BRX
and Western Klaza Zones, with a total of 46 holes successfully completed to
date."
Western BRX Zone
The Western BRX Zone is the main target of the 2014 diamond drill program. It is
a 750 m long, linear structure hosting high-grade gold and silver veins emplaced
alongside or in close proximity to a feldspar porphyry dyke. Systematic infill
and step-out diamond drilling in 2014 at the Western BRX Zone has further
confirmed the continuity of the structure while delineating areas of high-grade
gold and silver mineralization. Twelve of the thirteen holes reported from 2014
drilling have tested a 400 m section of this 750 m long zone. The other hole
(KL-14-146) appears to have entered an offset fault that post-dates
mineralization, before reaching the targeted Western BRX Zone.
Significant new results, including some from mineralized secondary structures,
are shown in the table below.

+ Represents the diamond drill hole length. True widths are estimated to be
approximately 80-90% of the interval.
(i)Gold equivalence (EQ) has been calculated using metal prices of $1300 per
ounce gold and $26.00 per ounce silver, to be consistent with earlier
calculations and assumes 100% recoveries of both metals.
Drilling and trenching at the road-accessible Klaza property since 2010 have
identified nine main mineralized structural zones and numerous subsidiary
structures within a 2,000 by 4,000 m corridor. Individually, the main zones
range from 1 to 75 m in width and are continuously mineralized over strike
lengths of 250 to 2,400 m. The zones have been traced over a cumulative strike
length of 9,400 m and all remain open for expansion along strike and to depth.
Maps, sections and an expanded assay list which includes copper, lead and zinc
values for the significant intervals can be viewed at the Company's website at
www.rockhavenresources.com. Additional results from the 2014 exploration program
at Klaza will be released once assays are received, compiled and evaluated.
All analyses for rock and core samples from the 2014 program were performed by
ALS Minerals with sample preparation in Whitehorse and assays and geochemical
analyses in North Vancouver. Core samples are routinely analyzed for gold by
fire assay followed by atomic absorption (Au-AA24) and 48 other elements by
inductively coupled plasma-mass spectrometry (ME-MS61). Samples that exceed the
detection limits of the routine methods are assayed for silver, copper, lead and
zinc by inductively coupled plasma-atomic emission spectroscopy (Ag/Cu/Pb/Zn -
OG62) and gold by gravimetric analysis (Au-GRA22). Rigorous procedures are in
place regarding sample collection, chain of custody and data entry. Certified
assay standards, coarse reject duplicates, field duplicates and blanks are
routinely inserted into the sample stream to ensure integrity of the assay
process. All of the results reported have passed the QAQC screening.
The 2014 program is managed by Archer, Cathro & Associates (1981) Limited
(Archer Cathro). Technical information in this news release has been approved by
Matthew R. Dumala, P.Eng., a geological engineer with Archer Cathro and
qualified person for the purpose of National Instrument 43-101.
