Rockhaven Reports First Assay Results from 2021 Exploration at its

Klaza Gold-Silver Project, Yukon

December 1 5, 20 21 - Rockhaven Resources Ltd. (TSX-V:RK) (“Rockhaven”) is pleased to

announce the first set of assay results from the 2021 exploration program at its 100% owned and

road accessible Klaza property, located in the Dawson Range Gold Belt of southern Yukon.

During summer and fall of 2021, a total of 14,256 m of drilling was completed in 72 holes. The

objectives of this drilling were: (1) expansion of existing mineral resources, (2) re-categorization

of some inferred mineral resources into indicated mineral resources, and (3) evaluation of

exploration targets that lie outside of the known mineral resource areas. This release reports initial

results from holes in and around mineral resources at the Central BRX and Central Klaza zones,

and from exploration at the Western BRX Extension, Western Chevron and Kelly Porphyry

targets.

Highlight assay results in this press release include:

Central BRX Zone

• 1.37 g/t gold, 79 g/t silver, 1.2% lead, and 0.8% zinc over 13.42 m (KL-21-509)

• 1.11 g/t gold, 53 g/t silver, 0.3% lead, and 0.6% zinc over 10.38 m (KL-21-507)

• 3.14 g/t gold, 554 g/t silver, 6.0% lead and 1.4% zinc over 1.38 m (KL-21-512)

• 13.50 g/t gold, 111 g/t silver, 0.7% lead, and 1.2% zinc over 0.81 m (KL-21-511)

• 6.92 g/t gold, 172 g/t silver, 3.1% lead, and 0.8% zinc over 1.26 m (KL-21-508)

Central Klaza Zone

• 1.55 g/t gold, 10 g/t silver, 0.1% lead and 0.3% zinc over 10.05 m (KL-21-518)

• 9.56 g/t gold, 31 g/t silver, 0.1% lead and 1.2% zinc over 0.69 m and

3.92 g/t gold, 1,225 g/t silver, 3.8% lead and 2.7% zinc over 0.55 m (KL-21-515)

Western BRX Extension

• 1,160 g/t silver, 8.4% lead and 5.2% zinc over 0.54 m (KL-21-492)

Western Chevron

• 2.69 g/t gold, 171 g/t silver, 2.1% lead and 4.4% zinc over 0.87 m (KL-21-501)

“These initial results from 2021 drilling are a first step in achieving the objectives of the 2021 drill

program, with expansion and infill drilling in and around known mineral resources consistently

returning grades in line with the mineral resource estimate , while also identifying potential new

discoveries at outside exploration targets,” stated Matt Turner, Rockhaven’s CEO. “Drilling

within the planned open pit returned solid intercepts that should contribute to the confidence in the

mineral resource estimate for the Klaza Deposit. Additionally, grades such as those seen in hole

KL-21-512, which lie immediately adjacent to the conceptual mine plan in the Klaza PEA (see

Rockhaven press release dated July 13, 2020 ), are highly encouraging and may provide the

opportunity to expand the contemplated open pit in that direction . We will continue to update

2

shareholders as assays are received from an additional 43 drill holes, all of which are in areas of

known mineralization.”

Maps showing the locations of completed drill holes and core photos from significant mineralized

veins can be viewed on the Rockhaven website at www.rockhavenresources.com.

Infill and Resource Expansion Drilling

Infill and resource expansion drilling was undertaken in the Central and Western BRX zones and

in the Eastern, Central and Western Klaza zones. Included in this release are results from the first

nine holes completed on the Central BRX and Central Klaza zones in 2021. Of particular

significance, all six holes announced from the Central BRX Zone intersected near surface

mineralization that lies in a poorly defined portion of the current mineral resource. Data from

2021 holes will be incorporated into a n updated mineral resource estima te, expected to be

completed in the second quarter of 2022 . Significant assays from early, infill and resource

expansion drill holes are shown in the following table.

intersects had contacts that were at or near perpendicular to core axis.

Western BRX Extension Exploration Target

A total of 1,456 m of drilling was completed in seven holes that form a continuous 1,060 m long

fence across the westerly projection of the Western BRX vein, the highest-grade gold zone

identified on the property to date. This drilling searched for the strike extension of the vein west

of a post-mineralization fault that truncates the known vein, in an overburden-covered area hosting

a number of previously untested geophysical anomalies. Veining was intersected in several of the

drill holes with the most notable result from KL-21-492, which returned 1,160 g/t silver, 8.41%

lead and 5.15% zinc over 0.54 m . The mineralogy and the bonanza grade silver assay likely

indicate a depositional setting that is more distal to the heat source than the veins comprising the

current resource . Veins in this area probably lie in a silver-lead-zinc rich portion of the

mineralizing system. This conclusion is supported by a single trench that was dug up -dip of the

drill intersection in hole KL-21-492, which exposed a 1 m wide vein of nearly massive galena with

assays still pending.

The results from this drill hole and trench are significant as they represent a s tep-out of 750 m

from the Western BRX Zone. Future drilling and surface trenching will assess the potential of this

new vein, working eastward to determine whether an area of gold enrichment is present closer to

the Western BRX Zone . Significant results from th is hole and others on the westerly fence are

shown in the table below.

Western Chevron Exploration Target

The Western Chevron target lies 800 m to the southwest of the Western BRX Zone, in the same

fault block. Several previous holes drilled in this lightly explored area returned encouraging

results. A total of 619.8 m of drilling was completed in 4 holes, 3 of which intersected significant

mineralization. These results are shown in the table below.

were at or near perpendicular to core axis.

Kelly Porphyry

The Kelly Porphyry target lies about 800 m southeast of the known mineral resources and is

believed to core the hydrothermal system that deposited the epithermal vein system. The porphyry

target is define d by a very large copper -molybdenum-gold soil geochemical anomaly with

coincident magnetic lows, chargeability highs (>70 ms) and resistivity lows (<100 ohm -m). A

total of 2,578 m of drilling was completed in nine drill holes on the Kelly Porphyry target in 2021.

While broad, significant intercepts were not encountered in this campaign, pervasive porphyry-

style stockwork veining and alteration was logged throughout the holes. Interpretation of the drill

results suggests that the 2021 holes may be located within the ‘pyrite halo’ that often encircles

nearly all porphyry centres. Additionally, several phases of Casino Suite intrusive rocks were

identified within the Kelly Porphyry target area, an important feature associated with the main

mineralizing event at the Casino deposit that lies approximately 100 km to the northwest of Klaza.

Lithogeochemical vectors indicate that the best potential for porphyry-style mineralization lies to

the northeast of the 2021 drill holes, in an area characterized by strong chargeability highs and

coincident resistivity lows.

QA/QC

All analyses for rock and core samples from the 2021 program were performed by ALS Minerals

with sample preparation in Whitehorse and assays and geochemical analyses in North Vancouver.

Core samples were routinely analyzed for gold by fire assay followed b y atomic absorption (Au-

AA24) and 48 other elements by inductively coupled plasma -mass spectrometry (ME -MS61).

Samples that exceeded the detection limits of the routine methods were 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 were in place regarding

sample collection, chain of custody and data entry. Certified assay standards, coarse reject

duplicates, field duplicat es and blanks were routinely inserted into the sample stream to ensure

integrity of the assay process. All of the results reported have passed the QA/QC screening.
