Freegold Mountain Project - Regional Geology• Property is underlain by the Paleozoic or

older metasedimentary and metavolcanic rocks of the Yukon-Tanana Terrain

• Extensively intruded by Jurassic to Late Cretaceous rocks of the Coast Plutonic Complex (Stikinia)

• Mid-Cretaceous rocks include the Dawson Range Batholith, Casino Granodiorite and Coffee Creek granite

• The above units are cut by Late Cretaceous sills and dykes of felsic to intermediate composition

• Property is transected by moderate to steep dipping northwest-trending faults which parallel the Tintina and Denali faults

Freegold Mountain Project - Property Geology• Property is bounded by two major structures, the North and

South Big Creek fault zones

• Between these two major structures are two sets of secondary structures – west to northwest and north to northwest – multiple reactivations

• Mineralization controlled by these two sets of structures

Nucleus and Revenue – Nucleus Deposit Geology• Most advanced exploration target on the property

• Geology dominated by variably altered basement metasedimentary and metavolcanic rocks, younger quartz monzonite and granidiorite and a quartz-feldspar porphyry dyke suite

Nucleus Deposit

Nucleus and Revenue – Revenue Zone Geology

• Variably altered granodiorite and quartz monzonite

• Feldspar porphyry dykes

• Centered around an intrusive breccia – Revenue Breccia

Revenue Zone

Page 10: Revenue Porphyry Au-Cu Project Freegold  Mountain, Yukon

NORTHERN FREEGOLD RESOURCESTSX.V: NFR

www. northernfreegold.com10

Nucleus and Revenue - Mineralization• Mineralization occurs within all basement and younger intrusive rocks and

appears to be structurally controlled

• Alteration includes extensive clay alteration, biotite, sericite and silica alteration

• Mineralization associated with pyrite/pyrrhotite + chalcopyrite +/-

molybdenum in veins, veinlets and infill in breccias and less commonly with

gold bearing quartz +/- arsenopyrite veins and veinlets

• Recent age dating indicates mineralization associated with one mineralizing

event - Classified as a Porphyry Au-Cu-Ag±Mo deposit

Nucleus and Revenue – Re-evaluation• Built database, went back and looked at soil geochemical survey, airborne

and surface geophysics and historic drilling in the Revenue area.

• Identified a significant gold and copper soil anomaly covering an area 6 km by 4 km (24 km2) extending from the Nucleus deposit eastward across the Revenue Zone

• Historical Drill results from the Revenue Zone has significant Au, Cu, Ag and Mo numbers over extended widths

2010 Program Objectives:• Continue to expand on the million ounce NI 43-101 inferred gold resource at

the Nucleus deposit

• Drill test the large scale gold and copper soil anomaly (6 x 4 km) which extends from the Nucleus deposit eastwards to beyond the Revenue Zone

Nucleus and Revenue – 2010 Exploration ProgramNucleus• ~ 4,500 m of diamond and

Reverse Circulation (RC) to expand the resource at the Nucleus deposit

Revenue• ~ 6,000 m of RC and diamond

drilling to systematically test several priority targets.

Nucleus and Revenue - Geophysics

• Titan-24 (Quantec Geoscience) Deep Penetrating IP/Resistivity Survey to identify large scale (porphyry gold-copper system) targets associated with and adjacent to Nucleus-Revenue system

Nucleus and Revenue Zone – 2010 ResultsHighlights

• Successful drill program in Nucleus zone; expands the Nucleus resource laterally and to depth

• Successful drill program in Revenue zone; defines significant near surface gold, copper and silver mineralization open laterally and to depth

• Titan Survey identifies 6 zones of interest over and around Revenue Zone and Nucleus Deposit

• Results from the Titan Survey combined with the drill results from Revenue Zone confirms a large scale mineralized system encompassing the Nucleus Deposit and extending east through the Revenue Zone

Revenue Zone – Initial 2011 Drill Results

• The holes reported here include in-fill and step-out holes drilled within and around the Revenue Target Deposit. Higher grade within extensive lower grade intervals

• The results of drilling to date expand on the size of the Revenue Target deposit and demonstrate the size potential of the deposit. The deposit is open laterally and at depth.

• Revenue zone Target Deposit to be upgraded to Inferred Resource.

Stoddart Zone – 2011 Titan 24 Results

• Titan Survey identified 12 First Priority Targets medium to high chargeability with medium to low resistivity

• Anomalies were identified over a strike length of 2.5km, widths of 2.5km and vertical extents in excess of 500m

• One of the 12 First Priority Targets corresponds to the 2007-2008 diamond drilling completed in the Stoddart Zone. This drilling intersected significant Cu-Ag-Au-Mo mineralization

• The Stoddart Zone porphyry mineralization may be part of a much larger porphyry system identified in the Nucleus and Revenue Zones, and may extend that porphyry system an additional 3 km along strike

Nucleus, Revenue and Stoddart Zone – Closing• Nucleus deposit is open laterally and to depth; based on drilling and

geophysics – excellent potential to expand the Indicated/Inferred Resource

• The results of drilling to date in and around the Revenue zone are highly encouraging as they continue to expand on the size of the Revenue Target deposit and demonstrate the size potential of the deposit. The deposit is open laterally and at depth

• Revenue zone Target Deposit to be upgraded to Inferred Resource

• Results from the 2010 Titan Survey combined with soil geochemistry and recent drill results from confirms a large scale mineralized system encompassing the Nucleus Deposit and extending east through the Revenue Zone

• The Stoddart Zone porphyry mineralization may be part of a much larger porphyry system identified in the Nucleus and Revenue Zones, and may extend that porphyry system an additional 3 km along strike
