Talon Metals (TSX:TLO) has intercepted a new high-grade nickel-copper mineralization approximately 2 miles outside of the current nickel-copper resource area at the Tamarack Nickel-Copper-Cobalt Project in Minnesota. The company believes it has confirmed a new “system” of high-grade nickel-copper mineralization in the Tamarack Intrusive Complex. The exploration team has called the new nickel mineralization the “Raptor Zone”, which intersects high-grade nickel in the first 6 out of 9 holes roughly 2 miles from the current resource area.
Brian Goldner, Chief Exploration and Operations Officer of Talon, commented in a press release: “New drilling shows us that the Tamarack Intrusive Complex can be a district-scale nickel-copper resource right here in the United States. We’ve moved nearly 2 miles outside of the Company’s current nickel-copper resource area and successfully intercepted high-grade nickel-copper in a different intrusion (new system) as compared to the current resource area.
“While still early in the process, these preliminary results provide definitive evidence that the Tamarack Intrusive Complex has district-scale potential, and as a consequence of these exciting initial results, we intend to make further exploration along the Tamarack Intrusive Complex a priority in 2023.
“Last year’s discovery of the shallow high-grade nickel mineralization in the CGO West area started with only a small 1.3-meter intercept of high-grade nickel massive sulphide – that mineralization ultimately grew to nearly 14 meters thick only 25 meters away. I expect this same thickening could occur in the new area called the “Raptor Zone”, especially with the amount of unexplored space we have to work with.”
Highlights from the results are as follows:
The potential for additional high-grade nickel-copper mineralization within the 11-mile-long Tamarack Intrusive Complex has been recognized by Talon for some time. Talon’s primary focus to date has been the discovery and delineation of the Main Zone, the CGO West area and the CGO East area (collectively referred to as the “Company’s nickel-copper resource area”). To accomplish this growth, Talon spent the past 2 years building a complete in-house exploration team, incorporating among other things, a fleet of five Talon-owned and staffed drill rigs, along with precision borehole and surface geophysical guidance equipment. With the advancement of the delineation work, Talon’s in-house team has now been tasked with evaluating the exploration upside over the entire length of the 11-mile-long Tamarack Intrusive Complex starting at the northern end of the complex where the “Raptor Zone” has been identified. The name “Raptor” has been chosen given the resemblance to the iconic predator’s profile that shows up in the magnetic survey (see Figure 2).
Since September 2022, Talon has completed 9 new drill holes outside of the Company’s nickel-copper resource area, 6 of which have already intersected high-grade nickel-copper mineralization. These intercepts occur in 2 new areas of mineralization within the larger “Raptor Zone”, including the “Raptor’s Crest” (previously referred to as the 264 Zone) located approximately 1.8 miles (3 km) north of the Company’s nickel-copper resource area and the “Raptor’s Head” (previously referred to as the 221 Zone) located approximately 1 mile (1.6 km) north of the Company’s nickel-copper resource area (see Figure 2). These two areas (Raptor’s Crest and Raptor’s Head) have very limited historic drilling, but assays do include high-grade nickel massive sulphide intercepts of up to 9.95% Ni1 and 9.33% Ni2 within these respective zones. Of note, in between the drill holes lie 1-mile (1.6 km) of ground that has never been drilled and therefore, this ground represents a high priority exploration target for the Company in 2023, given that it is bookended with high-grade nickel massive sulphide intercepts on both sides.
The Company’s recent drilling in the Raptor Zone has suggested that the intrusive depositing the high-grade nickel mineralization appears to be a completely different intrusive (i.e., a brand new “system” of mineralization) as compared to the Company’s nickel-copper resource area. Additionally, the nickel mineralization found in the Raptor Zone appears to be dominantly massive sulphide rip ups, suggesting that the massive sulphide was originally formed elsewhere and has been eroded and transported to where it currently resides. The Raptor Zone is following a similar trend (plunge and dip) and is parallel to the intrusive units in the Company’s nickel-coper resource area but lies at a different elevation below the resource and the down-dip projection of that structure lines up with the top of the Magnetotelluric (MT) anomaly, now named “Raptor’s Nest” (see Figure 3).
