Geology Comments

Apr 10, 2015 (Therese Pettigrew) - The Newman Todd property is located in the western part of the Red Lake Greenstone Belt and is underlain by volcano-sedimentary rocks of the Ball and Balmer Assemblages. Rock units trend NE and dip steeply to the SE, younging to the SE (Bullis et al, 2015).

Lithology

Lithology Comments

Mar 22, 2012 (A McKee) - Gold occurs in cm-scale quartz veins and associated with pyrite-pyrrhotite replacement mineralization. Sulphide mineralization is, in part, of replacement origin and typically occurs within wide intervals of strong silicification and brecciation. High grade gold mineralization appears to be focused along steep north to west trending structures that are internal or marginal to wide, lower grade breccia zones. (2.32536)

Apr 10, 2015 (Therese Pettigrew) - The most abundant rock units on the property are felsic crystal tuffs and ultramafics. The crystal tuffs cover most of the north portion of the claims, and the ultramafics dominate the southern and SE potion of the claims. The Newman Todd Structure (or NTS) is the main host of gold on the property and is primarily a body of breccia composed of fragments of silica, iron carbonate, with minor crystal tuff, iron formation and chert. The NTS ranges between 70 and 200 m wide, trending NE and steeply dipping to the east, with intermediate to mafic volcanic units forming the footwall and hangingwall. In the central part of the NTS, a thick brittle fault crosscuts the NTS at a high angle (the Hinge Fault Zone). This fault zone marks the northern limit of the magnetic high anomaly within the NDS and its surface expression is the small lake over the NTS. The Hinge Fault is auriferous (Bullis et al, 2015).

Mineralization

Mineralization Comments

Mar 22, 2012 (A McKee) - 2010: 3 DDH in this area returned assays including 25.70 g/t Au over 1 m, 23.5 g/t over 1 m including 15.7 g/t Au over 0.3 m. 2011: Confederation Minerals Ltd. Intersected 27.00 Metres of 5.95 g/t gold including 1.0 Metre of 139.0 g/t gold; 17.53 g/t gold over 5.0 meters; and numerous additional significant gold intercepts.

Oct 30, 2020 (Therese Pettigrew) - Extensive gold mineralization occurs in close proximity to the hanging wall contact. A total of 109 holes were drilled into the NTS by Confederation Minerals over the 1.8 km strike length and 94% of these holes intersected variable widths of 3 gpt Au or higher; 87% intersected variable widths of 5 gpt Au or higher; 41% intersected variable widths of 20 gpt Au or higher. Several styles of gold mineralization have been observed: 1) Gold occurs as free gold in quartz veins in both the hanging wall sequence and in the breccia. These veins tend to be blue-grey in colour and occasionally white. Coarse gold can be seen to occur in quartz-pyrite veins crosscutting both quartz-carbonate rock and felsic dykes. 2) Elevated gold values (up to 5 gpt) have been returned from a massive sulphide (pyrite and pyrrhotite) unit in the hanging wall in the NE breccia. 3) High-grade gold values have been returned from high sulphide and magnetite zones within the breccia (typically greater than 20% sulphide and magnetite combined). 4) Lower-grade gold values are often associated with slight increases in galena and arsenopyrite. 5) Sphalerite-bearing veins in quartz porphyry (hanging wall) often contain gold. The 2013 drilling program showed that gold mineralisation is present at very shallow levels within the Newman Todd Structure (NTS). During the early the part of the year, drilling was focused on the shallow, near-surface, upward extension of the mineralisation from swampy areas which could only be drilled when frozen. Results showed that the gold-bearing system begins at shallow depths below the surface. For example, hole NT-142 returned a 6 m interval grading 13.19 g/t gold between 52.0 and 58.0 m core length (approximately 41.5 to 51.5 m below surface). High grade gold mineralisation has been also been returned from surface trenches on the property. Some drill intersections closer to the surface, although lower grade overall when compared to other deeper intersections, can be seen to attain very wide core length intervals. For example, drill hole NT-131 intersected 38 m grading 1.30 g/t gold beginning at 75.0 m core length below the surface, and NT-135 returned 36.0 m core length grading 1.92 g/t gold beginning at 103.0 m core length below surface. One of the most significant assay intervals returned from the 2013 drilling was from hole NT-148, which is located on the northern-most section of holes, and which graded 32.57 g/t gold over a core interval of 7.0 m, approximately 168 to 175 m below surface. Deeper in the same hole, a 1.0 m interval, between 229.0 and 230.0 m core length assayed 174.11 g/t gold, including a 0.5 m section grading 342.0 g/t gold. This is one of numerous holes in the Hinge Zone and elsewhere on the property that demonstrate the presence of multiple zones of gold mineralisation. Holes NT-151 to NT-155 were drilled along three 25 m spaced drill lines in the northeast of the Hinge Zone, close to its boundary with the “NE Zone”. Drill highlights include a 9.5 m intersection grading 10.39 g/t gold, including 0.50 m at 103.0 g/t gold (hole NT-153). The high-grade gold mineralisation intersected in these holes is closely related to the hanging wall contact of the NTS, with zones occurring approximately 5 to 25 m away from the contact (Bullis et al, 2015).

Mar 13, 2024 (Sheree Hinz) - Drilling done by Renegade Gold Inc. in 2023 successfully intercepted high-grade mineralization and structures below previously tested depth of 300m. High-grade mineralization in the Hinge Fault corridor 400m below surface was found in hole NT-23-001 which intersected 1.63 g/t Au over 34.1 m, including 8.35 g/t Au over 3.5 m. Hole NT-23-002 extended known mineralization to a depth of over 550 m below surface with intersections of 2.02 g/t Au over 41.5 m, including 5.00 g/t Au over 9.5 m. Mineralization was also confirmed along strike with hole NT-23-003 which intersected 2.33 g/t Au over 41.9 m, including 9.63 g/t over 7.4 m (Renegade Gold Press Release, February 26, 2024).
