FLAGSHIP 100% OWNED WAWA GOLD PROJECT LOCATED 2 KM SOUTHEAST OF WAWA, NORTHERN ONTARIO
TWO MINERAL DEPOSITS; Surluga and Minto Mine South
Red Pine Exploration Inc. is a gold exploration company headquartered in Toronto, Ontario, Canada. The Company's common shares trade on the TSX Venture Exchange under the symbol "RPX". The Company is engaged in the acquisition and exploration of early stage exploration prospects in areas that have excellent potential for world-class mineral deposit discovery. Red Pine strives to increase shareholder value through exploration discoveries on 100% owned projects. The Wawa Gold Project is in the Michipicoten greenstone belt of Ontario, a region that has seen major investment by several producers in the last five years. Its land package hosts numerous historic gold mines and is 6,986 hectares in size. Led by Quentin Yarie, CEO, who has over 25 years of experience in mineral exploration, Red Pine is strengthening its position as a major mineral exploration and development player in the Michipicoten region.
Targeted Commodity: Gold
Property Size and Position:
167 patents / leases and 301 mining claims totalling 6,986 hectares within the McMurray Township, 2 km southeast of the Town of Wawa, Ontario.
The property has hosted numerous gold mines with historic production of over 120,000 ounces. To date, the largest gold deposit on the property is the Surluga Deposit.
Historically, more than 87,000 metres have been drilled on the property. At the Surluga Deposit, 252 surface holes totalling 45,346 metres and 1,339 underground holes totalling 41,753 metres.
While the property hosted numerous historical gold mines, these were owned by different operators and they were never geologically connected. With a comprehensive examination of the geology, geophysics, geochemistry, alteration mineralogy and structural geology, Red Pine has uncovered new targets.
Red Pine previously issued a 43-101 technical report for the Wawa Gold Project that includes over 700,000 ounces gold for the Surluga Deposit and the Minto Mine South Deposit combined, at an average grade of > 5 g/t (both Indicated and Inferred) (May 31, 2019). Both resources are accessible using existing historical underground infrastructure and both appear to be open along strike and at depth. 95% of the current resource is contained between surface and 350 metres depth.
In addition to the two (2) deposits currently identified on the property (the Surluga Deposit and the Minto Mine South Deposit), Red Pine has identified six additional exploration targets, along a gold-mineralization corridor that extends for more than 6 km (the Wawa Gold Corridor).
Red Pine is now ready to execute a strategic drill program designed to expand the existing NI 43-101 mineral resources and to explore the multiple additional highly prospective targets on the property. An estimated 15,000 metres of diamond drilling is planned in 2021 with the program continuing into 2022.
Wawa Project highlights
100% ownership (consolidated from 63.31%)
Two mineral deposits (Surluga and Minto Mine South) with currently estimated NI 43-101 resource of 1,307,000 tonnes @ 5.47 g/t gold for 230,000 ounces in the indicated category and 2,716,000 tonnes @ 5.39 g/t gold for 471,000 ounces in the inferred category1
Resource principally located between the surface and 300 metres vertical depth
Discovery of higher-grade mineralization in the Jubilee Shear Zone (host of the Surluga Deposit) down plunge of the existing resource
Preliminary drilling identified five (5) high-grade gold exploration targets that could grow the current resource: Hornblende, Minto B, Grace/Nyman, Minto Mine South and Parkhill # 4 shear zones
Potential for additional high-grade gold targets in the extension of the Jubilee Shear Zone, south of the Parkhill Fault
Quentin Yarie, President and CEO of Red Pine, stated, “After a great deal of work, we are happy to have consolidated Red Pine’s ownership of the Wawa Gold Project to 100%. Well funded, we are now set to resume our drilling and exploration programs and continue to grow the mineral resources on the property. Our earlier drill programs discovered mineralized zones beneath the Surluga Deposit and six other mineralized exploration targets adjacent to and beyond the current NI 43-101 resources. The focus of our 2021 exploration program will be to expand Surluga at depth and test the other targets. We are very pleased to now be able to fully develop and realize value as we grow 100% of the Wawa Gold Project for Red Pine shareholders.”
2021 Drilling and Exploration Program
The main target for diamond drilling in 2021 will be the Jubilee Shear Zone, host of the Surluga Deposit NI 43-101 mineral resource. The resource extension and definition drilling program will test the higher-grade gold-bearing structures previously identified by Red Pine. The Company will also test a number of exploration targets on the property that have the potential to be converted into resources as Red Pine continues to develop the project.
Extension of the Surluga Deposit NI 43-101 Resource
The Company will prioritize the extension of the higher-grade gold mineralization zone discovered in 2020, 300 metres down-dip of the current Surluga Deposit resource which generally lies from near-surface to a depth of 300 meters. Drilling the Jubilee Shear Zone extension at depth will also test the westernmost down-dip extension of the Minto Mine South Shear Zone, host of the second known resource on the Wawa Gold Project – the Minto Mine South Deposit.
2020 diamond drilling highlights in the Jubilee Shear Zone (Figure 1):
3.38 g/t gold over 13.3 m true width (“TW”), including 15.31 g/t gold over 1.64 m (SD-20-293)
5.2 g/t gold over 6.31 m TW including 15.7 g/t gold over 1.07 m and 12.4 g/t gold over 0.78 m (SD-20-289)
1.63 g/t gold over 23.34 m TW, including 17.32 g/t gold over 0.88 m and 14.72 g/t gold over 0.85 m (SD-20-292)
2.06 g/t gold over 11.8 m TW, including 3.67 g/t over 1.03 m and 7.45 g/t gold over 0.84 m (SD-20-291)
Figure 1- 2020 diamond drilling highlights in the Jubilee Shear Zone
A review of historical data suggests that the Jubilee Shear Zone’s northern extension, where limited drilling has been conducted, could host undiscovered zones of high-grade mineralization less than 300 metres below the surface. Geological data recorded in certain boreholes at the edge of the structure’s current footprint suggests potential proximity to stronger mineralized zones.
Targets beyond Surluga
The section below summarizes the exploration targets identified for further investigation.
Figure 2 – Exploration targets that will be tested in 2021
Jubilee Shear Zone south of the Parkhill Fault
In 2019 and 2020, Red Pine’s mechanized stripping and mapping program on the Jubilee Shear Zone, south of the Parkhill Fault, indicated structural attributes comparable to those found north of the fault. Shallow historical drilling by Duraine Mines Ltd. in 1981 combined with Red Pine’s geological mapping and channel sampling indicated gold mineralization. Drilling in this underexplored extension of the structure could expand shallow gold mineralization in the Jubilee Shear Zone to a 2 km strike length.
Diamond drilling highlights in the southern extension of the Jubilee Shear Zone (source AFRI 41N15NE0055 for Duraine Mines drilling results):
3.06 g/t gold over 2.70 m, including 41.14 g/t gold over 0.16 m (D81-02)
6.95 g/t gold over 1.01 m, including 15.39 g/t gold over 0.45 m (D81-04)
8.33 g/t gold over 1.34 m, including 24.34 g/t gold over 0.34 m (D81-08)
3.99 g/t gold over 1.00 m (S302 – RPX 2019 historic core sampling)
Grace and Nyman Shear Zones
The Grace and Nyman shear systems, host of the historical Darwin-Grace Mine, will be targeted for the discovery of shallow high-grade gold mineralization. Red Pine’s 2017 drilling demonstrated that high-grade gold mineralization is still present outside the mine’s historic footprint and that mineralization in the Nyman vein extends at depth. Red Pine’s mechanized stripping and mapping programs located the Grace Shear Zone extension, 110 metres north of the northernmost underground development of the Darwin-Grace Mine. The 2021 drilling program will test this new area in the structure.
Red Pine’s diamond drilling highlights in the Grace and Nyman Shear Zones:
42.22 g/t gold over 2.44 m, including 107.49 g/t gold over 0.54 m (DG-17-55 – Grace Shear Zone)
57.31 g/t gold over 3.14 m, including 138 g/t gold over 1.11 m (DG-17-56 – Grace Shear Zone)
10.1 g/t gold over 0.82 m (DG-17-66 – Nyman Shear Zone)
Hornblende Shear Zone
Red Pine’s diamond drilling in the Hornblende Shear Zone showed that gold mineralization, with potential zones of higher-grade mineralization, occurs over a strike length of at least 1.6 km. The largest zone of higher-grade mineralization, identified by historic drilling and confirmed by Red Pine’s drilling, occurs at the seventh level of the historical Surluga Mine. Red Pine’s drilling in the Hornblende Shear Zone also identified additional zones of broad mineralization with discrete zones of higher-grade mineralization in the structure.
Diamond drilling highlights in the Hornblende Shear Zone include:
5.61 g/t gold over 8.5 m, including 15.42 g/t gold over 2.9 m (HS-15-31)
2.91 g/t gold over 4.5 m, including 5.77 g/t gold over 1 m (HS-15-28)
3.18 g/t gold over 9.54 m, including 19.54 g/t gold over 0.61 m (U0007L7)
Minto B Shear Zone
The Minto B Shear Zone is located above the Jubilee Shear Zone, over the central and southern segments of the Surluga Deposit resource, north of the Parkhill Fault. Diamond drilling and mechanized stripping traced the structure over a strike length of 1 km and uncovered broad zones of gold mineralization. A higher-grade core also occurs in the structure, the size and grade could be defined with additional drilling. Diamond drilling in the Minto B Shear Zone will be undertaken concurrently with resource conversion, definition and exploration drilling in the Jubilee Shear Zone.
Diamond drilling highlights in the Minto B Shear Zone includes:
2.1 g/t gold over 10.6 m, including 3.7 g/t gold over 5.6 m (SD-18-256)
13.65 g/t gold over 2 m (SD-15-07)
4.69 g/t gold over 6.1 m, including 14.37 g/t gold over 1.52 m (U1683L5)
CURRENT DRILL PROGRAM HIGHLIGHTS AND TARGETS
The main target for diamond drilling in 2021 is the Jubilee Shear Zone, host of the Surluga Deposit NI 43-101 mineral resource. Red Pine is also targeting the Minto Mine Shear Zone, host of the Minto Mine Deposit NI 43-101 resource and the Sadowski Gold Zone. In the Jubilee Shear Zone, Red Pine is targeting potential zones of mineralization that were discovered down-dip and down-plunge of the the Surluga Deposit resource in earlier drilling programs. Our 2021 drilling program has been quite successful so far. In the southern part of the Jubilee Shear Zone, we have been able to extend our 2020 discovery located down-plunge of Surluga Deposit resource where we drilled up to 3.38 g/t over 13.38 meters (TW) in 2020. Further down-dip and down-plunge of our 2020 discovery, we have intersected in 2021 4.66 g/t gold over 12.24 meters (TW) and 25.73 g/t gold over 4.78 meters (TW). These intersections from our 2021 drilling program are now supporting a down-plunge continuity of at least 200 metres for gold mineralization in that discovery and proved that gold mineralization extends at least 400 meters down-plunge of the current resource of the Surluga Deposit. The intersection of 25.73 g/t gold over 4.78 meters (TW) also indicate that zones of high-grade gold mineralization exist in that discovered extension of the Surluga Deposit.
In addition to the discoveries made in the Jubilee Shear Zone, our 2021 drilling program identified high-grade gold mineralization down-dip of the current boundaries of the Minto Mine deposit with the intersection of 109.37 g/t gold (un-cut) over 2.68 metres true width (TW), including 314 g/t gold over 0.84 metres (TW), in the Minto Vein. This intersection suggests that the resource of the Minto Mine Deposit can be extended with additional drilling in the Minto Mine Shear Zone. We have also identified a new network of quartz veins hosting zones of high-grade gold mineralization. This vein network has been named the Sadowski Gold Zone and has been traced over 70 meters along strike. Significant intersections in the Sadowski Gold Zone include 13.95 g/t gold over 4.48 metres core length (CL) and 24.8 g/t gold over 1.15 meter (CL).
Figure 3 – Current Drill Holes September 2021
In parallel to our diamond drilling program, Red Pine conducted a prospecting, channel sampling and surface mapping program on and within the surroundings of the War Eagle claims, which are a prominent part of the Company’s strategy to strengthen the Wawa Gold land package. As part of this exploration program, Red Pine identification of new zones of gold mineralization in shear zones located on and adjacent to the company’s newly acquired War Eagle claims. The War Eagle mining claims exhibit gold showings with similar characteristics to the Wawa Gold project’s highly prospective Darwin-Grace structures, both of which are located in the McMurray Township, Michipicoten region of Ontario.
With two drill rigs active on site, we are drilling beyond the resource of the Surluga deposit to the north and south. We are also testing the Minto Mine Deposit and expanding our Sadowski discovery that are located above the southern exploration target in the Surluga Deposit. With the anticipated arrival of a third drill, we plan to test the property’s greenfield targets that include the southern segment of the Jubilee Shear Zone and of the mineralized structures forming the Darwin-Grace-Nyman vein and shear system. With a drilling program set to hit a 12,500 to 15,000 meters by December 2021, we have drilled, as of September 29th 2021, over 6,100 meters in the northern and southern extensions of the Surluga Deposit resource, the Minto Mine deposit and the Sadowski Gold Zone.
The current resource of the Surluga Deposit, totalling 3.6 Mt grading 5.26 g/t gold (Haywood Report, September 20th, 2021), is hosted in a geological structure named the Jubilee Shear Zone. The resource of the Surluga Deposit was estimated over a strike length of 1.9 km in the Jubilee Shear Zone and 95% of that resource is within 325 meters vertically from surface. The Jubilee Shear Zone is however known to extend over a strike length of a least its 5.5 kilometers and gold mineralization is known to occur in the Jubilee Shear Zone over most of its strike length. At depth, gold mineralization is known to extend to at least 800 meters below surface and remains open. The Jubilee Shear Zone is truncated in the middle of the Wawa Gold Property by a younger structure named the Parkhill Fault. The current resource of the Surluga Deposit is entirely located in the segment of the Jubilee Shear Zone north of the Parkhill Fault. The segment of the Jubilee Shear Zone south of the Parkhill Fault is known to be gold mineralized, but is significantly under-explored and defines the Jubilee Shear Zone South exploration target. Highlights from limited drilling in the segment of the Jubilee Shear Zone south of the Parkhill Fault include 8.33 g/t gold over 1.34 meter and 3.84 g/t gold over 2.15 meters. This is suggesting that the Jubilee Shear Zone has a good exploration potential for the discovery of additional mineralization beyond the current footprints of the resource at depth and laterally along strike.
Figure 4 – Cross Section of Jubilee South Section
The Jubilee Shear Zone is part of a much larger deformation system named the Wawa Gold Corridor. The Wawa Gold Corridor is an anastomosing network of shear zones amongst which the Jubilee Shear Zone is the largest zone of deformation known so far and the most extensively explored. Another shear zone of significance for exploration in the Wawa Gold Corridor is the Hornblende Shear Zone, located approximately 300 meters west of the Jubilee Shear Zone. The Hornblende Shear Zone was reached at the seventh level of the Surluga Mine shaft where underground development and diamond drilling indicated the presence of gold mineralization in the 2-6 g/t range over widths of 5 to 12 meters. Red Pine confirmed the presence of the zone of gold mineralization with the intersection of 5.61 g/t gold over 8.5 meters and also that gold mineralization extends to the surface 600 meters north with the intersection of 3.81 g/t gold over 6.1 meters. At a larger scale, Red Pine’s exploration work suggests that gold mineralization occurs in the Hornblende Shear Zone over a strike length of at least 2 kilometers. Additional drilling in the structure is however necessary to constrain the grade and geometry of those zones of mineralization.
The Minto Mine Shear Zone is hosting the Minto Mine Deposit that is hosting a resource totalling 0.459 Mt grading 6.83 g/t gold (Haywood Report, September 20th, 2021). The Minto Mine Deposit is overlying the Jubilee Shear Zone and is emerging as a high-quality satellite resource to the Surluga deposit. Our 2021 drilling discovered the extension of significant gold mineralization in the Minto Shear Zone beyond the current footprints of the Minto Mine Deposit and reveal a good exploration potential to expand the current resource. This exploration potential in the Minto Mine Shear Zone is tested concurrently with the southern extension of the Surluga Deposit in the Jubilee Shear Zone.
The Sadowski Gold Zone is formed by a network of quartz veins emplaced in sheared fractures. The vein network cover a strike length of at least 70 meters, and the individual quartz veins forming the network are pinching and swelling and contain zones of high-grade gold mineralization. More drilling is however necessary to confirm the size and geometry of the zones of high-grade gold mineralization in the Sadowski Gold Zone.
The Darwin-Grace-Nyman exploration target is associated with the historic Darwin-Grace Mine (17,634 gold ounces at 13.27 g/t Au) that was exploited from the early 1900s to the late 1930s. The Darwin-Grace Mine is located at the intersection of two geological structures, the NW-striking Grace shear zone and the ENE-striking Nyman Shear Zone. The surface trace of the Grace Shear Zone is confirmed over a strike length of 700 meters and hypothesized over an additional 800 meters of strike length. The northern extension of the Grace Shear Zone merges with the Jubilee Shear Zone, whereas to the south the structure extends on the War Eagle claims that we acquired in the spring of 2021. Historic and recent data indicates that the Darwin-Grace-Nyman mineralized system can host significant zones of high-grade mineralization. In the Grace Shear Zone, during the re-development of the Darwin-Grace mine in the 1930s, underground channel samples contained up to 2,146 g/t gold over 0.91 meter. Red Pine’s drilling in the Grace Shear Zone up-dip of the northern end of the mine workings intersected 57.31 g/t gold over 3.14 meters, indicating that high-grade mineralization extends beyond the footprints of the Darwin-Grace Mine. In the Nyman Shear Zone, mined from level 6 of the Darwin-Grace Mine, grab samples collected by Red Pine 400 meters east of the Darwin-Grace Mine contained up to 143 g/t gold. Red Pine then obtained 10.1 g/t gold over 0.82 meters with diamond drilling in the Nyman Shear Zone.
The Minto B Shear Zone forms an exploration target located between the northern end of the Minto Deposit and the southern part of the Surluga deposit current resources. Historic and drilling by Red Pine in the Minto B Shear Zone indicated the presence of a core of gold mineralization that is grading between 2 and 6 g/t over 3 to 10 meters. Example of intersections in the higher-grade core of the Minto B Shear Zone include 2.2 g/t gold over 6.9 meters (estimated true width) and 3.4 g/t gold over 6.2 meters (TW). Successful exploration leading to the definition of a mineral resource in the Minto B Shear Zone could provide zones of mineralization that could contribute to bridge the development of underground infrastructures between the Minto and Surluga deposits resources. Additional drilling remains necessary to constrain the size and geometry of the higher-grade core of the Minto B Shear Zone.
