Richfield drills 171 metres of 3.13 g/t Au in BW 91, and BW 90 extends zone eastward

November 23, 2010

QUESNEL, BC, Nov. 23 /PRNewswire/ – Richfield Ventures Corp. (TSX.V:RVC)
(“Richfield” or the “Company”) is pleased to report drill results for
four diamond drill holes on its Blackwater Gold Project approximately
100 km south of Vanderhoof, BC.

BW 91 returned very positive results. The top of the hole cut 171 metres
grading 3.13 g/t Au. This hole is 50 metres south of BW 87 (115 metres
@ 2.59 g/t Au including 57 metres of 4.79 g/t Au – see NR Nov 2, 2010).
It demonstrates southward continuity of the near-surface mineralization
between the two holes and leaves open the possibility of further
southward extension. BW 89, 91 and 92 are all on 100% Richfield owned
ground and are about 300 metres west-northwest of BW 90.

BW 90, drilled 100 m east of BW 74 (231.96 metres of 0.75 g/t Au – see
NR Sept 2, 2010) intersected 148 metres of 1.77 g/t Au. The hole also
intersected 39 metres of 3.06 g/t Au near the bottom. This hole is on
the Jarrit claim, where Richfield can earn a 100% interest. It expands
the mineralized zone at least 100 metres to the east and remains open
in that direction.

BW 89 intersected 35 metres of 0.82 g/t and 49 metres of 0.88 g/t in the
upper 110 metres. Anomalous gold values continue to the bottom near 400

BW 92 has gold mineralization throughout with values in four broad zones
from the bedrock-overburden contact to 315 metres.

Peter Bernier, President and CEO observed “We are thrilled by these
latest results, with 171 metres of 3.13 g/t Au BW 91 is one of our best
intersections to date and BW 90 extends the zone to the east leaving it
open in that direction.”

Richfield is well-funded and plans to continue drilling with two rigs to
mid-December. Drilling will resume in January.  Holes will be targeted
to further explore and delineate the bulk gold deposit which is
developing at the Blackwater Gold Project.

Drill map, sections and strip logs for individual holes will be posted
on the company website.

uncut, length-weighted average values.

Quality Assurance

Richfield has implemented a rigorous quality assurance/quality control
program at the Blackwater property using best industry practice and
supervised by Dirk Tempelman-Kluit. The program includes chain of
custody of samples from drill to laboratory. Drill core is sawn in half
at the property and for each sample half of the core from one metre
intervals is placed in plastic bags and sealed. The remainder is
retained in core boxes stored at the project camp.

A standard sample, a blank sample, or a duplicate sample is inserted
into the sample stream every tenth sample. Three certified ore assay
laboratory standards are used in the program, and are supplied by CDN
Resource Laboratories Ltd., an independent laboratory located in
Langley, BC. Samples including the blanks, standards and duplicates,
are shipped by bonded courier to Eco Tech Stewart Group Laboratories in
Kamloops, BC, an internationally recognized analytical services
provider. Rejects selected at random are sent to Acme Labs of
Vancouver, BC for check assays. In total 212 quality control samples (3
% of all 1639 samples) were analyzed. Richfield detected no significant
QA/QC issues during review of the data.
