District History Coeur d’ Alene Mining District: 1885-2009

• 2nd largest silver producing district in world• Over 1 billion ounces produced• Production mainly from narrow, steeply

dipping high grade veins• Average annual production grades from silver

mines range from 10 to 50 opt• Bunker Hill and other mines produced significant

silver at lower grades as by product production

Crescent Mine-District Location Crescent is located in the Silver Belt

between Bunker Hill and Sunshine Mines Bunker and Sunshine produced nearly half

of district silver – 489 million ounces• Sunshine 328 million ounces• Bunker Hill 161 million ounces

• Includes 25 million from Crescent

Crescent Mine History

Crescent History Exploration/Development/Mining

• Began in late 1800’s Bunker Hill Company began acquiring

Project claims in 1926. Bunker Hill reports production 1917-1981

• 978,750 tons• 25,139,655 ounces silver• Grade of 27 oz Ag / ton

Crescent History Cont. Bunker Hill milling records report silver

recovery in:• Sulfide ores:

• 95% recovery• Oxidized ore:

• 80 to 85% recovery

Crescent History Cont. Average grade of concentrate produced 250 oz Ag 6% Pb 8% Cu 4% Sb

4.5% As 29% Fe 32% S 0.002% Bi 0% Zn 4% Insoluble

Bunker Hill Operations

Of Crescent

Bunker Hill Operations Crescent Surface adits Internal raises Internal shafts up and down Mined with overhand stoping methods Mill on site built in 30’s

Bunker Hill Operations Cont. Yreka Crosscut from Bunker Hill in 1963 Hauled ore UG to Bunker Hill shaft for

hoisting Crescent was small part of BH operation Mined @ 150 t/d in 60’s, 70’s & 80’s

Bunker Hill Operations Cont. Apparent lack of mineralization in Yreka

crosscut discouraged exploration in 60’s and 70’s between Bunker Hill & Crescent

Late 70’s White, Juras & Radford developed new stratigaphic model

Proposed new exploration targets

Bunker Hill Operations Cont. Ore mined from 12 different veins Most production from

• Alhambra Fault• East Footwall Vein• Hook Vein• BJ Vein• South Vein – conflicting data

In some years production averaged +50 opt

Bunker Hill Operations Cont. Mine closed in 1983 At closure mining reserves (resources)

were calculated and classified in the proven, probable and possible categories

Calculation completed by Don Springer, an independent consulting geologist and a QP as defined in 43-101 regulations

Bunker Hill Operations Cont. Combined reserves were stated @:

• 395,380 tons• 23.9 oz Ag / ton• 9,395,380 ounces of Ag

A 10 year mine life @ 150 t/d Mine life reduced need for immediate

exploration using new model

SNS Silver Corporation

SNS Acquisition Purchase property from Shoshone County,

Idaho & the Environmental Protection Agency

January 2, 2007 Cash purchase – US $650,000

SNS Exploration Drill tested and confirmed stratigraphic

model in upper country• Brian White & Dwight Juras

Encountered favorable stratigraphy (St. Regis) on HW of Alhambra Fault in upper country

South Vein located in St. Regis & Revett rocks

Stratigraphic Cross Section

SNS Exploration Continued Diamond drilling completed during 2007

and 2008• 70 surface holes• 30 underground holes• Total of 103,215 feet

Completed underground rehabilitation for UG drill platforms

Extended Hooper Tunnel 1000’ west

Syringa Exploration Inc.

Syringa Exploration Inc. Letter of Intent to JV with SNS Silver Corp.

• Nearing agreement Syringa proposes to earn a 51% interest

• Bringing mine to production• Delineating resources

Experienced operations and admin management

Availability of SNS geologists & staff

Management Michael Gross – 20 years in Silver Valley

• Managed Lucky Friday• Extensive narrow vein experience• Build effective teams

Erik Panke – 22 years with Washington Group• Field accountant to senior business manager

with projects up to $1 billion

Contract Mining Services Contract United Mine Services and Mine

Fabrication & Machine Sister companies & going concerns United Mine Services

• Administration is place• Experienced supervisors and miners• Underground mining equipment in inventory

Contract Services Mine Fabrication & Machine

• Full service fabrication and repair facility• Eliminates need for a complete repair shop at

mine• Will receive priority service

UMS Management have a large network of mining personnel experienced in narrow vein UG mining.

Operations Crescent mine offers near term production

• Less than a year Fully permitted

• Convert MSHA classification from exploration to operations

• Work in progress to resolve water discharge issues left from Sterling Silver

• Long term agreement in place

Operations Cont. Must re-establish secondary exit

• Re-hab Big Creek #4 level to daylight Install new muck handling facilities for new

resources Drive access to South Vein Establish stopes Install sandfill system

Processing Custom mill ore Two facilities available in Silver Valley

• Coeur Mill @ Coeur Mine• Probably lease and self operate

• New Jersey Mining Company Mill• Purchase mill capacity

Both have permitted tailings facilities Both within easy hauling distance

Summary Syringa / UMS Experienced management Resources for 5.6 years @ 250 t/d Resource grade is sufficient UMS has manpower and equipment Administrative system for UMS in place UMS management knows where to source

miners

Summary Syringa / UMS 5.6 year mine life @ 250 t/d @ 18.7 opt @ $13 Ag, gross Ag value is $230 /ton 9.4 million oz inferred Ag resource below
