Rockhaven Resources Ltd. (TSX VENTURE:RK) ("Rockhaven") is pleased to announce
additional results from the 2013 exploration program at the eastern portion of
its 100% owned Klaza gold-silver property, located in the Dawson Gold Belt of
southwestern Yukon.
News Release Highlights:
-- A new high-grade gold discovery made at the Pearl Zone in two widely
spaced trenches that returned 28.2 g/t gold and 359 g/t silver (35.38
g/t gold EQ) over 1.20 m and 19.75 g/t gold and 148 g/t silver (22.71
g/t gold EQ) over 1.25 m; and,
-- The 2013 trenching has nearly doubled the size of the known mineralized
structural corridor on the Klaza property from 2.4 km to 4 km in length
and from 1.8 km to 2 km in width.
"Excavator trenching within the recently purchased eastern portion of the Klaza
property resulted in new high-grade vein exposures and has substantially
expanded the target area," stated Matt Turner, CEO of Rockhaven. "Results from
the remaining 22 trenches of the 2013 program, which tested the high grade BRX
Zone, will be released once assays have been compiled."
Pearl Zone
The newly discovered Pearl Zone is the ninth and most northerly mineralized
structure identified at the Klaza property. It was identified by two excavator
trench exposures grading 28.2 g/t gold and 359 g/t silver (35.38 g/t gold EQ)
over 1.20 m and 19.75 g/t gold and 148 g/t silver (22.71 g/t gold EQ) over 1.25
m. These exposures are located 450 m apart and occur along a topographic linear
that marks a strongly oxidized vein. Detailed follow-up trenching and drilling
are planned for 2014 to fully evaluate this new high-grade gold and silver
discovery, which is open to extension along strike in both directions.
Eastern Klaza and Far Eastern Klaza Zones
Excavator trenching has increased the known strike length of the Klaza Zone to
3,700 m. The Eastern and Far Eastern Klaza Zones are located proximal to the
Mount Nansen Porphyry Complex, the intrusive body that is thought to have been
the main hydrothermal driver for the mineralized system at the Klaza property.
Mineralization within these areas has lower silver to gold ratios than the veins
to the Western and Central Klaza Zones and is locally elevated in copper and
molybdenum. The Eastern and Far Eastern Klaza Zones are characterized by sheeted
vein complexes and surrounding alteration envelopes, which coalesce to form a
series of 10 to 100 m thick mineralized bands. Four, widely spaced trenches were
completed in 2013 to test the Eastern and Far Eastern Zones. TR-13-42 returned
0.69 g/t gold and 3.43 g/t silver (0.75 g/t gold EQ) over 53.95 m while
TR-13-40EXT averaged 0.84 g/t gold and 4.01 g/t silver (0.91 g/t gold EQ) over
18.65 m.
Chevron Zone
Excavator trenching within the southeastern portion of the Klaza property also
identified the eastern extension of the Chevron Zone, located 1,300 m to the
south of the Eastern Klaza Zone. TR-13-46 returned 1.35 g/t gold and 12.60 g/t
silver (1.60 g/t gold EQ) over 13.07 m, including 2.26 g/t gold and 22.34 g/t
silver (2.70 g/t gold EQ) over 5.98 m. The showing is associated with a
coincident linear magnetic low and an elevated multi-element soil geochemical
anomaly which is typical of other mineralized structures identified at the Klaza
property. The Chevron Zone has an inferred length of 2,000 m and remains open
along strike in both directions.
A total of ten excavator trenches tested targets in this eastern part of the
Klaza property in 2013, and the most significant assay results are shown in the
table below. Maps showing the locations of the trenches can be viewed on
Rockhaven's website at www.rockhavenresources.com.

350 m of TR-53 where true width is estimated to be approximately 25% of the
interval.

2013 Exploration Program
Rockhaven's 2013 exploration program at its road-accessible Klaza project
consisted of approximately 5,000 m of excavator trenching in 38 trenches that
focused on extending and confirming continuity within the Klaza and BRX Zones as
well as discovering new mineralized zones in other areas of the property that
had not previously been systematically explored. Results from the remaining 22
trenches that tested the Central and Western BRX Zones will be released once
assays are received, compiled and evaluated. Additionally, metallurgical test
work on samples from the BRX and Eastern Klaza Zones is underway and results
will be announced once finalized.
All significant assays from 2010, 2011, 2012 and 2013 diamond drilling and
excavator trenching can be viewed on the Company's website
(www.rockhavenresources.com), including geological maps, cross-sections and
assay histograms.
Trench samples included in this press release were processed in 36 sample
batches with each batch including one assay standard and one blank sample.
Analytical work was done by ALS Minerals with sample preparation in Whitehorse
and assays and geochemical analyses in North Vancouver. All samples were
routinely analyzed for gold by fire assay followed by atomic absorption
(Au-AA24) and 48 other elements by four acid digestion (ME-MS61). All overlimit
values were determined for gold by fire assay and gravimetric finish (Au-GRA22)
and for silver using Ag-OG46 and Ag-GRA21). All gold and silver grades reported
in this release were calculated from the assay results. All standards and blanks
passed QAQC reviews.
The 2013 program was 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.
