INTRODUCTION

This report is being submitted to fulfill the requirements of the Mining Act of Ontario.

This is proof of exploration work completed for the purpose of assessment credits. This report

titled “Assessment Report for the Diamond Exploration Drill Program, April-May 2008” and

dated October 23, 2008, contains the technical results and exploration expenditures relating to

Devonshire Resources Ltd’s (“Devonshire” or the “Company”) 2008 Spring diamond drilling

program carried out on its TCH Diamond Property-Pic Claim Block (“Property”) between April

15th and May 24th, 2008. The Property is situated in the Killala Lake area of north-central

Ontario within in the Thunder Bay Mining Division, NTS map sheet 42E2 (see Figure 1). The

2008 program consisted of 13 drill holes totaling 1,504 metres that tested several magnetic,

electromagnetic, and kimberlite indicator mineral anomalies for their diamond (kimberlite)

potential. Toronto-based consultants A.C.A. Howe International Limited (“Howe”) were

retained to provide personnel (one geologist) and technical supervision of the drilling program.

Devonshire (formerly Ripple Lake Diamonds Inc) is a publicly trading Vancouver-based

junior exploration company (TSXV-DSH) engaged in diamond exploration in Ontario and

Nunavut. Devonshire holds a 100% interest in the Property.

TCH DIAMOND PROPERTY - PIC CLAIM BLOCK

The Property consists of seven (7) mining claims- numbers 30084013 to 30084019

inclusive (Figure 2)- consisting of 108 claim units held in the name of Ripple Lake Diamonds

Inc. Table 1 below summarizes the current assessment status of the claims.

PROPERTY TOPOGRAPHY AND VEGETATION

The topography of the Property area consists of low rolling to rugged hills with numerous

lakes and swamp filled valleys typical of the Canadian Shield. The elevation ranges from

approximately 1,000 ft. to 1,200 ft. above sea level. Glacio-lacustrene deposits are generally

restricted to low areas and may reach considerable depth in some of the larger drainage basins,

but overburden is generally thin in most areas.

The vegetation in the area is boreal forest. On the higher ground the vegetation is

predominantly spruce, birch and poplar with alder and maple undergrowth. Thick cedar swamps

are characteristic of the low wet areas located throughout project area. All creeks and river

systems drain southerly toward Lake Superior.

GENERAL GEOLOGY

The Property lies at the junction of the Wawa and Quetico subprovinces of the Superior

Structural Province of the Canadian Shield. The rocks comprise east-west trending interbedded

Archean meta-sedimentary and meta-volcanic rocks intruded by granitic and mafic intrusive

rocks. Younger Proterozoic intrusions include the Marathon diabase dyke swarm and alkalic

intrusions, of the Coldwell and Prairie Lake alkalic-carbonatite complexes and lamprophyre

dykes. The large number of dykes mapped in the area is clearly evident in the airborne magnetic

survey as long linear anomalies with a variety of strikes. Including are some distinct magnetic

lows which appear to reflect a north-northeast set of lamprophyre dykes.

The Trans-Superior Tectonic Zone (TSTZ) extends north-northeast through the area and

appears to be the locus of the considerable intrusive activity present. The TSTZ is similar to other

tectonic features in the Canadian Shield, such as the Kapuskasing Structural Zone and the Lake

Timiskaming Structural, along which diamond deposits have been found. Indeed, diamondiferous

kimberlites have been found in Michigan on the southern extension of the TSTZ. These major

structures provide deep-seated zones of weakness that tap into the mantle and provide conduits

along which kimberlites ascend.


6

The intrusions which host diamond deposits are controlled by regional geology and tectonic

processes. The details of the local property geology are largely immaterial in the emplacement

diamond deposits.

In glaciated terrain where much of the overburden is exotic it is important to understand

the glacial history to establish the provenance of kimberlite indicator mineral anomalies. From

glacial striae there are 2 ice flow directions at 220o and 170o – 190o with the 220o direction being

the oldest (OGS, 2000a). The 220o direction is present throughout the area while the 170o – 190o

direction is only present in the south. A sub-glacial ‘lodgement’ till with material derived from

local bedrock is present almost everywhere, affords the best sample medium. Many of the glacial

deposits related to glacial retreat contain carbonate in the matrix derived from the closest

Palaeozoic rocks a long way away in the James Bay Lowlands. Both glaciofluvial and

glaciolacustrene deposits are present that can re-arrange and mask indicator mineral trains. Post

glacial landforms such as sand dunes and shoreline features which can also affect the disposition

of the till are also present. The Ontario Geological Survey (“OGS”) offers no glacial transport

distance for the area (OGS, 2000a), so an estimate of the proximity of the kimberlite source rocks

cannot be made.

PREVIOUS EXPLORATION ACTIVITY

Historical Work

Most of the previous historical work in the general area has been focused on gold and

base metal exploration and is not directly applicable to diamond exploration. However, there are

kimberlites and kimberlite-like ultramafic lamprophyre dykes associated with the TSTZ in

Michigan. There are also lamprophyre dykes mapped in several places in the Killala Lake area.

These dykes appear as several distinct north-trending magnetic lows that pass throughout the

area.

Two diatremes are known in the Ripple Lake area: the Ripple Lake diatreme and the

McKellar diatreme. Until recently, both diatremes were believed to be related to the Coldwell

Carbonatite-Alkalic Complex near Marathon. In November 2003, material collected from the

Ripple Lake diatreme yielded three microdiamonds from a 19.83 kg sample (Sample WN 6/1).

This was the first direct indication of primary diamond mineralization in the area. The presence


7

of diamonds indicated diamond-bearing mantle beneath the area, and significantly enhances the

diamond potential of the region.

In 1999, the OGS completed a KIM sampling program in the Marathon area and

identified seven areas and six individual anomalies with potential for diamond mineralization

(OGS, 2000a). The OGS also conducted a high resolution helicopter airborne magnetic and

electromagnetic geophysical survey of the area in 2000. Subsequently Devonshire engaged

Colorado-based Condor Consulting Inc. (“Condor”) to make a geophysical interpretation of the

OGS airborne magnetic and electromagnetic materials in order to identify kimberlite pipe-like

anomalies.

Property Activities: 2004 and 2005

In 2004, KM Diamond Exploration Ltd. prospected and sampled for kimberlite and

kimberlite indicator minerals (KIM) in the Killala Lake area. The main objective of the work

was to sample the study area for diamonds and indicator minerals, with a density of

approximately 2.15 samples per one km2. Local detailed sampling was done in 2005 (Figure 3)

and focused in on several key areas selected on the basis of the following criteria including

demonstrated high concentrations of KIM grains (according to the results of sampling in 2004)

and identified as magnetic or EM anomalies based the various geophysical interpretations.

The results of the exploration on the aforementioned claim blocks identified the presence of

a coarse picroilmenite halo that extends NNE-N for approximately 3 km with an average width of

500 m. Within this halo, a small micaceous kimberlite-like fragment was recovered in one of the

till samples. A number of positive and negative magnetic anomalies and EM anomalies were

also identified within the claim blocks.

DEVONSHIRE DIAMOND DRILLING: APRIL – MAY 2008

Between April 15th and May 24th 2008, Devonshire completed 13 holes totaling 1,500

metres of drilling on five of the Property’s seven claims. A skid-mounted hydro core diamond

drill, using thin walled AQTK rods and a 2-man crew (Photos 1 & 2), was contracted from

Chenier Drilling Services Ltd. of Hanmer, Ontario. Chenier maintained two 2-man crews on site

for the majority of the project, each crew working two 10-hour shifts. The Peninsula Inn in

Marathon, located approximately 100 km SE of the project site, was used as the logistics base for

the duration of the drilling program. Access to the Property was via existing logging roads,

though additional earthworks were needed to reach the drilling targets and prepare drill sites.

The following table summarizes the details for all 13 drillholes. Hole locations are

presented in Figure 3. Descriptive drill logs and cross sections are presented in Appendix B.

Following the completion of a hole, drill collars were marked with flagged posts. The core

was left stacked in several locations in the bush. Core from holes TCH-08-01 to TCH-08-08 was

stored at a central lay-down area off the logging access road at 528,000E and 5,434,700N. For

the remaining five holes, drill core was left stacked at the drill collar locations. The following are

brief descriptions of the 13 holes. Drill sections have been provided for only those holes which

intersected possible kimberlite lithologies: holes TCH-08-07 and 08.

TCH-08-01 (Claim 3008418)

Hole TCH-08-01 tested a positive magnetic anomaly identified by Condor on the North

Shore of Route Lake. The drill was able to set up directly over the anomaly and drilled to a depth

of 120 m. The hole intersected a moderately magnetic diabase dyke that is interpreted to be the

cause of the anomaly.

TCH-08-02 (Claim 3008416)

Hole TCH-08-02 tested a coincident EM/negative magnetic anomaly identified by Condor

over a small pot lake. The anomaly lay east of the coarse picroilmenite halo in an “up-ice”

direction. The hole was set up on the east side of the lake due to spring thaw conditions (Photo 1,

page 6) and was drilled at an inclination of -68 and bearing of 270o for 75 m. The hole was

terminated after encountering a small, very fine grained diabase dyke that is interpreted to be the

cause of the anomaly.

TCH-08-03 (Claim 3008416)

Hole TCH-08-03 tested an EM anomaly over a small lake that was identified by Orequest

Consultants. This anomaly lies approximately 200 m east of the coarse picroilmenite halo. The

drill was located along the lake’s shoreline and the hole drilled toward the centre of the anomaly.

A fine grained diabase dyke similar to that which was encountered in Hole TCH-08-02 was

encountered and the hole was terminated.

TCH-08-04 (Claim 3008414)

Hole TCH-08-04 tested a magnetic high identified by Orequest Consultants lying on the

east side of a small lake. This target is approximately 1 km up-ice of the concentrated sample

area. The hole intersected only granite and gneiss and the cause of the magnetic anomaly


12

remains undetermined.

TCH-08-05 (Claim 3008415)

Hole TCH-08-05 tested a magnetic high anomaly located on the eastern edge of the coarse

picroilmenite halo. The hole intersected only granite and gneiss and the cause of the magnetic

anomaly remains undetermined.

TCH-08-06 (Claim 3008415)

Hole TCH-08-06 tested a magnetic high anomaly located within the coarse picroilmenite

halo and ~300 m directly up ice of where the kimberlite-like sample was recovered in 2005. The

hole intersected a moderately magnetic gneiss that may be the cause of the anomaly.

TCH-08-07 (Claim 3008415)

Hole TCH-08-07 tested a magnetic low anomaly located at the southern edge of the coarse

picroilmenite halo. The hole intersected a micaceous, highly magnetic, fine to medium grained

dyke with inequigranular texture. The rock has tentatively been described as lamprophyre

pending detailed petrographic study. A drill cross section of the hole is presented in Figure 5.

TCH-08-08 (Claim 3008415)

Hole TCH-08-08 was drilled directly up ice of TCH-08-07 and adjacent to where the

kimberlite-like sample was recovered in 2005. The hole intersected a dyke similar to that found

in hole TCH-08-07. The intercept in this borehole however contained a 40 cm intercept of much

coarser grained material. The rock has again been tentatively described as lamprophyre pending

a detailed petrographic study. A drill cross section of the hole is presented in Figure 6.

TCH-08-09 - TCH-08-13 (Claim 3008413)

Holes TCH-08-09 to 13 were designed to test the northern part of the coarse picroilmenite

halo for the lamprophyre lithology similar to that found in holes TCH-08-07 and 08. All the

holes were drilled at -45 dip, perpendicular to ice flow direction, as well as the strike of the

previously encountered dykes. For the most part, the holes intersected only granite and gneiss

with some minor sections of diabase dyke. The holes did not intersect the lamprophyre lithology

encountered in holes TCH-08-07 and 08.
