Trillium Gold (TSXV:TGM) Discovers Large Mineralizing System at Newman Todd in Red Lake

After acquiring a significant land package and consolidating its position in the Red Lake Mining District in Canada, Trilliium Gold Mines Inc (TSXX:TGM) (OTC:TGLDF) has announced this morning it has discovered multiple gold anomalies along its Confederation Belt Properties in Red Lake.

A spaciotemporal geochemical hydrocarbon sampling program was completed during the summer of 2021 at the Confederation Belt properties. This survey unveiled numerous gold pathfinder anomalies with rating categories ranging from 1-6. This has now confirmed and established the gold exploration potential of Trillium’s properties. These properties form a 39,300 hectare contiguous land position directly on trend with other discoveries currently unfolding in the district and therefore makes Trillium Gold’s position highly valuable.

The gold pathfinder anomalies identified by the survey conducted by Activation Laboratories will now serve as the priority targets for the company’s second for of exploration work in the 2022 field season. Trillium can use the sampling and concurrent prospecting program to generate multiple drill targets.

Red Lake Mining District has already produced 29 million ounces of high-grade gold. Red Lake is one of the country’s premier mining districts, and has infrastructure, million, and roads in place for efficient drilling and exploration. The survey focused on some key blocks at the properties, to focus on known base metal and minor gold mineralization intersected in historical drilling, including the Joy Block. A significant portion o the Joy-Copperlode Blocks are covered by variably conductive outwash and deglaciation sediments.

Information from the surveys according to the press release includes:

The three smaller grids in the southwest of the Joy Block were designed as orientation surveys over known base metal and minor gold mineralization intersected in historical drilling. A large portion of the Joy-Copperlode Blocks are covered by variably conductive outwash and deglaciation sediments (not locally derived) and despite no outcrop identified in these areas, all three returned anomalies, the western-most two confirming the method over known drill hole results.

Based on a synthesis of previous work reviewed to date by Company geologists, these anomalies appear likely spatially associated with more than one type of control (i.e., late-stage structural, lithological, as well as possible earlier structures (syn-volcanic?), as previously interpreted in historical work). The location of the anomalies is directly on trend with regional-scale faults (as at Great Bear’s Dixie Project) and provide a new framework on which to focus gold exploration in the belt and region.

Several new target areas have also been confirmed where historically very little exploration work has been conducted (e.g., the northern-most anomaly on the Copperlode property, I-anomaly, Figure 1). These new discoveries provide exciting new targets for follow-up work.

On the Copperlode West block, the F-anomaly is a highly-rated anomaly cut by a NW-SE trending magnetic lineament (possibly D2 orientation?) and represents one of the more encouraging targets in the area. Also of high-rating is the I–anomaly which lies on the western extension of an EM conductor in an area with no known historical geological, geochemical or geophysical surveys. The J-anomaly was identified as a potential Redox zone by Actlabs, similar to that at the Dixie Hinge and Limb zones sampled by Great Bear Resources (news release August 1, 2019).

The Block B anomaly is also highly rated and shows parallel responses coincident with a magnetic high trend, and coincident with or flanking a NE trending EM conductor.

The Block 1 anomalies lie within stratigraphy representing the eastern extension of that hosting the copper-molybdenum mineralization near Fredart Lake. The two geochemical signatures appear to be on strike from one another, hosted by iron formation or ferruginous sediments. There has been very little historical work in this area. The Lucky 7 anomaly lies within an EM conductor trend that has been drilled, off-property, intersecting gold values up to 4 g/t over 1.5ft. Grab samples in the drilled area also ran up to 13 g/t gold.

The Block 2 anomaly, among the highest rated by Actlabs, shows a significant number of high contrast peaks over a large, 600m x 450m area. Actlabs identify it as a segmented nested-halo anomaly coincident to that of the Redox zone. The potential for gold mineralization here is believed to possibly exist directly below this anomaly.

The Fly-Moth N and S grids serve as extensions to exploration work on known prospective and mineralized trends associated with the past-producing South Bay Mine. There are anomalous gold values in historical lithogeochemical samples in the general area around the mine; however, samples further towards the southwest were not assayed for gold. The SGH grids fill in the data gaps and successfully highlight new gold anomalies. These anomalies are highly rated and show characteristics of Redox Zones as well.

Here, the controls on processes responsible for the development of these anomalies likely reflect a complex interplay between lithology and structure. There appears to be some, but not exclusive, spatial lithological control locally (e.g., near Triangle Lake) as the anomalies are associated with minor intrusive rocks which themselves were previously interpreted as fault controlled. However, one anomaly coincides directly with a previously mapped rhyolite tuff unit suggesting the possibility of lithologically hosted gold.

Equally, the geometry of elevated gold in this package of rocks could be suggestive of syn-volcanic fault-controlled mineralization. At the southern edge of Triangle Lake, historical work identified anomalous gold that coincides with a previously mapped fault. These types of relationships bear investigating for refinement or confirmation of ideas with follow-up exploration work planned for 2022.

The Block 3 anomaly coincides with several important features: a regional-scale fault trace, a major volcanic break (cf. Thurston et al, 1980), and a property scale transition from felsic to mafic volcanic rocks. Historical work on the property identified several sulphide zones and/or geophysical conductors. The few historical drill holes in the general area, inconsistently sampled for base metals and even more infrequently for precious metals, do show elevated copper, zinc and gold in these sulphide horizons.

Conversely, in the direct vicinity of the anomaly, virtually no geochemical work has been performed, and there are only two known drill holes, the locations of which remain uncertain.

After recently acquiring the Confederation Lake assemblage from Infinite Ore Corp., the company has become one of the dominant explorers in the Red Lake Mining District. The Eastern Vision property holdings at Confederation Lake include 16,991 hectares, and give Trillium control over a large portion of the assemblage. Most importantly, it gives the company control over a contiguous land package that now covers over 100 km of favourable structure on trend with Great Bear Resources’ Dixie Deposit.
