The following is a list of properties or contiguous Property Groups on which Copper Reef holds a Royalty in the Flin Flon Greenstone Belt of Manitoba and Saskatchewan. The Basemetal Properties are subdivided into Dominantly Zinc; Copper- Zinc; and dominantly Copper. Generally they are all polymetallic with appreciable contents of Zinc, Copper, Silver and Gold and occasionally Lead.
Copper Reef holds a $0.75/t royalty on the McIlvenna property owned by Foran Mining. The property which surrounds Copper Reef's Hanson Lake Property is reported to contain roughly 29 million tonnes, using a $45 (US)/t NSR cut off, (see Foran Mining Corporation news release March 27, 2013). Copper Reef has a royalty on any addition discoveries or tonnes that may be found on this property.
This is a large property in Saskatchewan held by Foran Mining where Copper Reef holds a 2%NSR on any resource existing or ever discovered on the property. In 1990, past operators estimated a historical mineral resource for the Bigstone deposit of 3.75 million tonnes grading 2.03 per cent Cu and 0.33 gram per tonne gold using a 1-per-cent Cu cut-off. A sensitivity analysis was also completed at that time using cut-off grades from 1 per cent to 2.5 per cent Cu, which is presented in the attached table.ESTIMATE SENSITIVITY ANALYSIS (1)
This property in the Hanson Lake area owned by Foran Mining is contiguous to the south east to their Macilvenna Property. Copper Reef holds a 2% NSR on metals derived from this property

Copper Reef holds a1% NSR on Calinex's Pine Bay Mine Property in the main camp just south of Copper Reef's Albert,-Lew-Amulet-Mur Property.
The project host several significant mineral occurrences established by previous operators, including a known VMS deposit (Pine Bay). A report sourced from government of Manitoba archives, dated 1970 and completed by Wright Engineers Limited, estimated via polygonal method that the deposit at pine bay contains 667,900 tons grading 3.90% copper at a cutoff grade of 2.0% Cu, 783,000 tons grading 3.54% Cu at a cutoff grade of 1.5% Cu, and 1,113,200 tons grading 2.76% Cu at a cutoff grade of 1.0% Cu. Readers are cautioned that estimates are historic in nature and do not comply with national instrument 43-101.
The Royalties also extend on to the Cabin Zinc Zone; the former Baker Patton Mine which is underlain by a very large gravity anomaly possibly indicative of copper-zinc massive sulphides; Anomaly 8 , a unexplained large gravity and EM anomaly between the Pine Bay Mine and the Cabin Zinc zone; the former producer the Don Jon Mine and any other discovery that might be made on the property.

The Bruce Morgan-Woosey- Cook claim groups are the only properties in the Chisel Basin Stratigraphic group that host a number of zinc deposits that is not controlled by Hudbay. This is the same stratigraphic sequence that is host to Hudbay's recently developed large Lalor Lake Zinc-Copper Gold Mine. Copper Reef's Bruce-Morgan Property contains the largest zinc deposit (200,000 tonnes with a historic grade of 8% Zn) not held by Hudbay in the Snow Lake camp. The Morgan deposit's alteration zone extends to the north and this has not been drilled. The alteration is similar to that which is found in the Chisel Basin and beneath Lalor. Copper Reefs also has on these properties a number of other prospects including the down plunge extension Hudbay's Pen Zone (665,000 tonnes of 8.3% Zinc only 200 m to the south west of the Cook Lake property) as well as other showings with drill intersections of Copper and Zinc, such as the Irene Lake Prospect (4.58% copper, 3.82% Zinc, 38.8 g/t Silver, 1.5 g/t Au over 0.5 m) and the GW (10% Zn, 2.1g/t gold, 28.9 g/t silver over 0.6m). The Property also contains a number of undrilled airborne anomalies from various surveys, one of which is drill ready and is very close the GW prospect. What is, however most exciting is there has been little to no deep penetrating geophysical surveys on these properties below 150-200m of the type that found the Lalor deposit. Recently Copper Reef has picked up 4 addition claims for staking costs along this key stratigraphy.
The rocks that host the Snow Lake Volcanogenic Massive Sulphide (VMS) deposits occur within two distinct volcanic sequences: Shown in Figure 3 below are the two main volcanic sequences
A lower primitive volcanic sequence (Anderson) with a simple bimodal lithologies dominated by basaltic and felsic volcanic rocks. This sequence has produces the smaller (less than 5 million tonnes) copper rich deposits such as the Anderson, Stall and Rod mines. The alteration zones from the hydrothermal fluids circulating along fracture zones produced small VMS deposits usually at or near the Basaltic and felsic volcanic contacts.
An upper more evolved (the magma had more time to fractionate) volcanic sequences (Chisel), composed of intermediate to felsic rocks with considerable breccia dominate the zinc rich deposits of the chisel sequences. The alteration zones are more complex and more extensive having been able to strip (leach) the great amount of volcanic breccias in this sequence of their metals to be redeposited into generally larger Zinc Rich VMS deposits. This is the sequence that dominated Copper Reef's property.
Between the two sequences is the mud horizon composed of barren massive sulphide muds that represent a quiescent period between the volcanic eruptions, intrusions and subsequent alteration and deposit formation that produce and occur within the underlying primitive dominantly mafic sequence and the overlying more evolved dominately intermediate to felsic sequence. This barren massive sulphides mud make an excellent geophysical conductor but is not associated with economic mineralization although it may flank deposits of the lower sequence. The 'Foot-Mud horizon' (thick red dashed line) is a pyritic, fine-grained volcaniclastic unit located at the contact between the Anderson ('primitive arc') and Chisel ('mature or evolved arc') sequences.
The Lower Chisel supracrustal rocks contain two discrete components. The first consists of felsic and mafic volcaniclastic rocks, which are derived by mass wasting of a source terrane located to the west, and a geochemically distinctive basalt flow (Snell) that was derived from more mature and evolved arc magmatism than that responsible for the underlying Anderson sequence. The second component is a suite of differentiated basalt, andesite, dacite and rhyolite flows that are geochemically distinct. The Zn-Cu VMS deposits are spatially associated with rhyolite flow-dome complexes lying atop this latter succession. Ubiquitous pillows in the mafic flows, lobe and tongue facies in rhyolite flows, and graded bedding in mafic volcaniclastic rocks indicate that the Lower Chisel rocks were deposited subaqueously. The Lower Chisel sequence is cut by a wide variety of intrusive rocks, ranging from dikes less than a metre across to large plutons several kilometers in diameter. Most of these intrusions are demonstrably synvolcanic, and many can be clearly related to specific extrusive equivalents. The abundant (locally up to 50% by volume) synvolcanic dikes support the hypothesis that rifting and caldera development likely accompanied accumulation of the Lower Chisel sequence. The 1.7 km by 7.3 km synvolcanic Richard intrusive complex is a long-lived intrusion that played an integral role in generating and sustaining the Chisel-Lalor VMS system. The synvolcanic character of the Richard intrusive complex is clearly supported by a U-Pb zircon date of 1889 +8/6 Ma and: 1) the presence of miarolitic cavities, which indicate shallow depth of emplacement; 2) geochemical similarity of the Richard tonalite and the overlying ore-hosting Chisel and Ghost rhyolite flows; 3) an increase in intensity of regional-scale semiconformable alteration zones in the Lower Chisel sequence close to the Richard intrusive complex; and 4) internal vein-breccia systems, which suggest epizonal intrusion.
The volcanic sequences of the Snow Lake arc assemblage contain prominent zones of alteration that visibly affect approximately 25% of the volcanic strata and associated synvolcanic intrusions. These alteration zones, which were formed by synvolcanic hydrothermal activity, were subsequently recrystallized during 1.81 Ga regional metamorphism and can be readily recognized by their unique metamorphic mineral assemblages. Centimetre-scale, euhedral crystals of chlorite, phlogopitic biotite, amphibole, muscovite, garnet and staurolite are common within metamorphically recrystallized semiconformable alteration zones. Recrystallized discordant alteration zones also contain coarse-grained kyanite and andalusite.
The first, and oldest, hydrothermal event occurs in the Anderson sequence rocks is focused within the Anderson and Daly felsic extrusive complexes. It is interpreted to be genetically related to formation of the Anderson, Stall and Rod Cu-Zn VMS deposits, in the former complex, and the Raindrop and Pot lake base metal occurrences, in the latter. This hydrothermal activity also affected the underlying Sneath intrusive complex, where it is manifested, most typically, as 'fracture-controlled' zones of alteration. These are interpreted to result from 'collapse' of the hydrothermal system into the subvolcanic intrusion as it cooled. The alteration caused by this hydrothermal activity includes both stacked, semiconformable zones, 35 km long and as much as 1000 m in total thickness, and discordant alteration 'pipes' that commonly terminate upsection at known VMS deposits and occurrences. These alteration zones are truncated by a late phase of the Sneath intrusive complex, which is considered evidence of the coeval nature of the volcanism, alteration and plutonism.
The second hydrothermal event took place at the end of Anderson sequence volcanism. This hydrothermal activity resulted in silica and epidote addition to Welch basalt at the top of the Anderson sequence. A 300-500 m thick zone of alteration was produced directly underlying the 'Foot-Mud tuff-exhalite' at the top of the Anderson sequence. Both the alteration and the Foot-Mud exhalite have the same strike length as the underlying Sneath subvolcanic intrusion.
The third hydrothermal event is located within Lower Chisel volcanic rocks and is spatially associated with Lower Chisel intrusive rocks, in particular dikes of the 'Powderhouse' dacite and early phases of the Richard intrusive complex. Resultant alteration by the hydrothermal fluids, which is largely confined to the Edwards mafic volcaniclastic rocks, is interpreted to be synvolcanic and related to generation of VMS deposits, as it only affects strata underlying the Chisel-Chisel North-Ghost-Lost-Lalor VMS horizon. The alteration zone is truncated to the west by late phases of the Richard intrusive complex and by late faulting. An alteration system underlying the Cook Lake and Bomber VMS occurrences trends to the southwest into a large alteration system along Parisian Creek, Woosey Lake and Morgan Lake; it may represent the western extension of the 'Chisel footwall' alteration system.
The geology of Copper Reef's property and showing are shown in Figure 5, along with other deposits of the Chisel Basin, most noted Lalor approximately 2 km from Copper Reef's property boundary.
The Bruce Morgan and Woosey properties are underlain by rocks of the Early Proterozoic Snow Lake arc assemblage. These rocks consist predominantly of variably altered dacitic to basaltic volcanic breccias, agglomerates, tuffs and pillowed flows. The entire sequence has been intruded by syn-volcanic tonalite, concordant gabbroic sills and discordant granodiorite plugs. Four mineralized/ cross cutting alteration zones (Morgan, DW, Mullen and Bud zones) have been identified by mapping and diamond drilling. Potential exists for the discovery of new mineralized zones, along the Morgan and DW Horizons. In addition, potential also exists for locating new massive sulphide zones associated with several untested Spectrem (Hudbay) and VTEM electromagnetic anomalies.
