Bayhorse Silver Commences Underground Drill Program

Bayhorse Silver Inc, (BHS: TSX -V, BHSIF: OTCQB, 7KXN: FRANKFURT) (the “Company”

or “Bayhorse”) reports that it has commenced the first stage of its underground drill program at its

Bayhorse Silver Mine in Baker County, Oregon, USA.

The first drill holes are to confirm the Big Do g hanging wall mineralization, where prior drill results

has identified silver grades of 6.75 oz/t over 6 meters, (BHS22-08) and Grab samples taken from the Big

Dog zone returned 218.2 oz/t (6,786.76 g/t) and 30.17 oz/t (938.4 g/t) silver respectively, while a Goldilocks

sample returned 145.05 oz/t (4,511.5 g/t) silver. (BHS22-07)

The second stage of underground drilling will be to target a low resistivity zone identified from the

recent VTEM survey, that starts immediately to the west of the western end of the current underground

workings. ( Figure 1 – Proposed drill targets).

The known strike of the Big Dog hanging wall zone is 100 meters (330 feet) with a 12 meter (40 foot

known vertical extent.

A surface drill program is currently in the permitting stage targeting the large low resistivity zone on

the SE corner of the Bayhorse Idaho property, then the two smaller low resistivity zones immediately

to north, to determine whether a copper porphyry exists on the Idaho property.

There are possibly two different mineralized targets on the newly acquired Idaho claims. A Bayhorse

Mine style silver rich massive sulphide target related to the strong magnetic signatures and a possibly

Hercules Silver-type copper porphyry target marked by the strong minimal Resistivity results.

Bayhorse CEO, Graeme O’Neill, comments that the low resistivity anomaly both i mmediately west

and east of the Bayhorse Mine underground workings, makes it a priority for further drill testing. As

well the low resistivity anomalies in the east of the Idaho property, may significantly increase the

discovery potential of a copper porphyry deposit as found at Hercules Silver property, 44 km to the

north in similar geological terrain.

Due to the historic reported gold grades of up to 10 g/t at the Bayhorse Mine, (Silver King Mines,

1984) and presence of high grade gold properties in close proximity to the Bayhorse Mine (Gleason, 8

km to the west, Connor Creek, 6 km to the north) the Company’s senior geological consultants believe

it possible that the silver- rich Bayhorse Mine epithermal mineralization may be underlain by a gold -

rich zone.

Figure 1 Proposed drill targets

Dr. Clay Conway, P.Geol., has mapped rhyolite -hosted mineralization east of the Snake River in the

area underlain by the strong magnetic anomalies . This raises the possibility that another Bayhorse

Silver rich deposit may be found at the hydrothermally altered rhyolite contacts.

It has long been known there is a strong genetic and spatial relationship between porphyry plutons

(which are the source of the hot fluids and metals) and outlying or overlying epithermals, skarns,

mantos and even vein systems. If the metals stay in the pluton or close to its margins it may end up as

a Cu porphyry. If in addition the fluids move upwards along conduits, then this could result in

precious metal epithermal mineralization like the Bayhorse high grade silver deposit.

About Bayhorse Silver Inc.

Bayhorse Silver Inc. is an exploration and production company with a 100% interest in the historic

Bayhorse Silver Mine located in Oregon, USA. With state of the art Steinert Ore -Sorting technology

reducing waste rock entering the processing stream by up to 85%, we have created a minimum

environmental impact facility capable of mining 200 tons of mineralization per day and the ability to

process and supply 3,600 tons per year of silver/copper/antimony concentrate ranging between 7,500

to 15,000 g/t silver and 10-12% copper, 10-12% antimony, and 15-18% zinc using standard flotation

processing at its milling facility in nearby Payette County, Idaho, USA, with an offtake agreement in

place with Ocean Partners UK Limited. The Company also has an option to acquire an 80% interest in

the Brandywine high grade silver/gold property located in B.C. Canada. The Company has an

experienced management and technical team with extensive mining expertise in both exploration and

building mines.
