The objective of this program was to further define previously identified overburden targets in order to refine the probable location of the bedrock source of gold anomalism.
HIGHLIGHTS:
- Two significant, discrete, high-priority gold anomalies defined.
- High proportions of “modified” and “pristine” gold grains within both these anomalies suggest distance to the primary source of the mineralization to be between 500-1,000 metres.
- An additional 15 precious and base metal anomalies identified.
As part of its exploration strategy to target highly prospective, underexplored mineralized belts with high known metal endowment, Coventry recently secured a substantial package of mineral rights to become the second-largest ground holder in the Rainy River Greenstone Belt.
The process of sampling glacial till and then using gold grain counting together with conventional analytical techniques led directly to the discovery of the Rainy River Gold Deposit. This relatively new methodology is based on glacial erosion and down-ice transportation of primary mineralization. Importantly the shape or morphology of gold grains is changed as they are liberated and transported during glacial erosion. The modified shape provides indications of the proximity of any gold grains in the glacial till to the primary source, as illustrated in Figure 2. The Company’s recently completed RC drilling program sought to further refine previously identified gold anomalies in glacial overburden at the Project.
The drilling program targeted four high-priority gold anomalies (Conqueror, Royal, Aries and Martin) and three base metal anomalies (Scylla, Charybdis and Bellepheron) generated from the Company’s initial overburden RC drilling program, completed during the winter of 2012, as well as from historical anomalies delineated by previous explorers that have not been subject to systematic follow-up work (Figure 1).
Overburden samples were collected for gold grain counts (undertaken by consultants Overburden Drilling Management (ODM) of Ottawa, Ontario) as well as analysis with conventional geochemical methods. Heavy mineral concentrates (HMC) samples were also collected from glacial till samples and from bottom-of-hole bedrock samples, for analysis with conventional multi-element analytical techniques.
Gold grain count data have been received for all 145 samples of glacial till collected during drilling. A summary of these results is presented in Table 1. Conventional precious and base metal analytical data are yet to be received, but are expected within 2-3 weeks. The conventional analytical results may enhance the interpretation of the results described below, and may highlight anomalous quantities of pathfinder elements that may further assist in the location of the source of the target anomalies.
Conqueror Anomaly
The Conqueror Anomaly (Figures 1 and 3) was delineated by a previous explorer in 2007 when 90 gold grains were reported in a sample of glacial till from a single overburden RC drillhole. Half of these gold grains were “modified” or “pristine” in morphology, suggesting a local source of mineralization. Follow-up work was never undertaken.
The Company recently completed eight RC drillholes, up-ice to the northeast of the initial anomalous sample to better define the potential source of the anomalism. Samples from five of these holes returned significantly anomalous results that averaged more than 10 gold grains per sample (see Table 1; Figure 3).
Drilling defined a gold-in-till “train” up to 950m wide, with a strike length greater than 1.4 km. This “train” remains open along strike (Figure 3). The dominance of modified and pristine gold grains (Table 1) indicates that the source of the gold is relatively proximal (interpreted to be approximately 500m-1,000m from the sample locations). Encouragingly, the Conqueror Anomaly is adjacent to a prominent, ovoid-shaped magnetic anomaly and is located along the interpreted trace of the large-scale Pinewood Fault (Figure 3). These are geological and structural features that may be associated with mineralization.
The Conqueror Anomaly is a very high-priority target. Further limited RC drilling is required to define the overburden anomalism prior to testing with diamond drilling, however the dominance of “modified” and “pristine” grains suggests that a possible source to the mineralization is close.
Royal Anomaly
The Royal Anomaly (Figure 4) was delineated during the Company’s RC drilling program in 2012. A highly-anomalous hole contained 428 gold grains, with an average of 36 gold grains per sample. A total of seven follow up RC drillholes were completed recently (Table 1) along two fences spaced 400m apart to the NNE of the anomalous 2012 drillhole, in an area that is interpreted to be the “up-ice flow” direction (Figure 4). Holes drilled immediately along strike from the interpreted “up-ice” position returned low results. However a single hole at the eastern end of the southern-most drill fence returned strongly-anomalous gold grain counts in the upper part of the hole, with a maximum of 67 grains recorded in a single sample, 51% of these being “modified” or “pristine” in morphology (Table 1).
It is interpreted that this recent anomalous drillhole may represent the top part of a gold-in-till “train” with a possible source “up-ice” to the northeast, less than 550m away. The “head” of the “train”, or potential source of the anomaly, appears to be closed off by a line of regional RC drillholes completed by the Company in 2012. The overall extent of the gold-in-till “train” may extend over a strike of about 2.4 km and is up to 500m wide (Figure 4).
The Royal Anomaly is a priority target that warrants infill RC drilling to narrow the bedrock gold source on a 100m drill pattern prior to testing by diamond drilling.
Aries Anomaly
A total of seven RC drillholes were completed at the Aries Anomaly (Figure 1) to follow-up on a pit that was excavated by Coventry in 2012 which returned 42 gold grains, 19% of which were “modified” or “pristine”. Of the seven drillholes completed, anomalous gold grain counts were recorded in four drillholes (Table 1), with a maximum of 49 gold grains recorded in a single sample (29% “modified” or “pristine”).
Further work is required to determine the significance of this anomaly.
Martin Anomaly
A total of six RC drillholes were completed at the Martin Anomaly to follow-up on previous work, which included RC drilling and pitting by Coventry in 2012, as well as similar work by previous explorers during the 1990’s. All six drillholes returned anomalous gold grain counts, but grains were dominated by reshaped morphologies (Table 1). A maximum of 61 grains were recorded in a single sample (16% pristine and modified).
Further work will be undertaken to assess the likelihood of possible other local sources associated with gold mineralization that may be obscured by the swamping effect of the distally-sourced, “reshaped” gold grains.
Base Metal Anomalies
A total of 18 RC drillholes were completed at the Scylla, Charybdis and Bellepheron Base Metal Anomalies (Figure 1 and Table 1) where previous work had delineated HMC geochemical results worthy of additional follow-up. Conventional precious and base metal assay results from HMC samples derived from glacial till and silt samples from these drillholes are yet to be received.
Elevated gold grain counts were returned from a single RC drillhole completed at the Scylla Anomaly, however the pending HMC assay data is required to determine the significance of this anomaly as the target is principally base metal in nature.
Additional Precious and Base Metal Anomalies
Significant compilation and interpretation of historic exploration data as well as the data the Company has derived itself has led to the recognition of at least 15 additional precious and base metal anomalies within the glacial overburden that blankets about 95% of the Rainy River Greenstone Belt.
These anomalies highlight the prospectivity of the Rainy River Greenstone Belt. They also demonstrate the low level of exploration maturity of the district, which, despite hosting a multi-million ounce gold deposit, has been subject to very little previous exploration.
Further Exploration
Once all assay results have been received and evaluated the Company will be in a position to plan follow-up RC and diamond drilling, in particular focusing on the Conqueror and Royal Anomalies. The Company anticipates the outstanding assay results will be received within the next two to three weeks.
