Rockhaven Resources Ltd. (TSX VENTURE:RK) ("Rockhaven") is pleased to announce
results for twelve additional drill holes from the Western BRX Zone at its
100%-owned and road-accessible Klaza property, located in the Dawson Range Gold
Belt of southern Yukon. The most recent results continue to delineate areas of
high-grade gold and silver mineralization within the Western BRX Zone (See News
Release dated July 15th 2014 and July 22nd 2014). The current 12,000 m diamond
drill program is focusing on the BRX and Klaza Zones which are two of the nine
well-mineralized structural zones that have been identified on the property.
Highlights from the new drill holes testing the Western BRX Zone are as follows:
-- 26.71 g/t gold and 172 g/t silver (30.15 g/t gold EQ(i)) over 2.98 m
including 38.20 g/t gold and 333 g/t silver (44.86 g/t gold EQ) over
1.16 m - Hole 150
-- 22.43 g/t gold and 245 g/t silver (27.33 g/t gold EQ) over 3.21 m
including 64.90 g/t gold and 725 g/t silver (79.40 g/t gold EQ) over
0.72 m - Hole 151
-- 11.10 g/t gold and 86.8 g/t silver (12.84 g/t gold EQ) over 2.10 m -
Hole 152
-- 14.30 g/t gold and 142 g/t silver (17.14 g/t gold EQ) over 2.06 m

"The current drill program is proving to be highly successful and is validating
that the Western BRX Zone is a significant gold-silver discovery," stated Matt
Turner, CEO of Rockhaven Resources. "The new holes continue to indicate
exceptional continuity and size potential and are encouraging Rockhaven to test
this target further along strike and at depth."
Western BRX Zone
The Western BRX Zone is the main target of the 2014 diamond drill program. The
zone consists of three linear vein structures which have been traced over a 750
m strike length and from surface to a maximum down-dip depth of 400 m. The
highest grade veins are emplaced directly adjacent to or in close proximity to
the hanging wall (BRXh) and footwall (BRXf) contacts of a feldspar porphyry dyke
that can be traced along the length of the zone. A secondary vein (BRXb),
located 20 to 70 m into the hanging wall of the dyke, is oriented slightly
oblique to the main veins. This vein appears to be unaffected by cross-cut
faults that off-set the main veins and may represent a later-stage mineralizing
event.
A total of 23 of the 25 holes reported from 2014 drilling at the Western BRX
Zone have tested a 580 m section of this 750 m long zone. The other two holes
have defined a post-mineralization cross-fault that off-sets the zone.
Significant new results 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.
^ KL-14-149 appears to have entered an offset fault that post-dates
mineralization before testing the Western BRX Zone structure.
KL-14-159 is an exploration hole from elsewhere on the property. Results
from this hole are pending.
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.
In 2014, a total of 9,500 m of diamond drilling has been completed in 54 holes
at the Klaza property. 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 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.
