Bayhorse Silver Underground Drilling Underway At The Bayhorse Silver Mine, CEO Discusses

Bayhorse Concentrate Antimony Content.

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

or “Bayhorse”) announces that underground diamond drilling is underway beneath the Company’s

silver/copper/antimony rich Bayhorse Silver Mine in Oregon, USA.

Diamond drilling is targeting the large low -resistivity anomaly that lies beneath the

silver/copper/antimony rich bearing rhyolite at the Bayhorse Silver Mine. The 1.5 +km (5,000 feet)

anomaly appears to have a vertical extent of 500 m (1,650 ft) from 600 m (1,980 ft) above sea level to

100 m (330 ft) above sea level and a width of up to 100 m (330 ft).

The Company anticipates good drilling ground for a large portion of the drill hole , estimating at least

+/- 30 meters (100 feet) of drill core per shift, intersecting the top of the anomaly 150 m (495 ft) down

hole with a projected termination depth of 257 m (850 ft) at the east side of the anomaly.

Antimony – In addition to its high Silver/Copper content, the Bayhorse mineralization, tetrahedrite,

contains a significant amount of Antimony, a critical mineral that is mostly imported into the U.S .

Prior testing has shown Antimony to be between 10% - 12% of the Bayhorse concentrate. With the

recent ban by China of exporting antimony into the U.S., that is a highly sought after component of

both explosives and flame retardants, prices are expected to increase for the near future.

In the sections image below, line 1040 lies directly beneath the diamond drill location, while line 1050

is 100 m (330 ft) east of and just outside the underground workings.

The Bayhorse exploration model holds that the silver/copper/antimony rich mineralized rhyolite at the

Bayhorse Silver Mine could have its source in underlying shallow granites that may be conductive

porphyry copper.

Bayhorse CEO, Graeme O’Neill, comments “the recent significant increase in the price of Antimony

to US$16 per lb, and predicted to go higher (mining.com.au), adds to the already significant silver and

copper values in the Bayhorse mineralization, not taking into account what we may intercept between

the Bayhorse Mine and the anomaly. A s the Bayhorse mineralization, tetrahedrite, is refractory in

nature, and the Sunshine Process, developed by the Sunshine Mine, Kellogg, Idaho, separates the

antimony and the sulphur without roasting, testing is planned on utilizing the Sunshine Process on the

Bayhorse concentrate to separate the Antimony from the silver/copper in the concentrate for potential

added value.”

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 and the Pegasus Project, in Washington County, Idaho.

The Bayhorse Silver Mine and the Pegasus Project are 44 km southwest of Hercules Metals’ porphyry

copper discovery. The Bayhorse Mine includes a state of the art Steinert Ore -Sorting technology

reducing waste rock entering the processing stream by up to 85% . The Company has 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 concentrate ranging between 7,500

to 15,000 g/t 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.
