The Hammerdown Deformation Zone (HDZ) is a broad structurally complex zone of sheared and faulted rocks which straddles the contact between the felsic dominated Catchers Pond Group and predominantly mafic volcanics of the Lush’s Bight Group. The HDZ is host to the Orion, Muddy Shag, Hammerdown and Rumbullion mesothermal high grade gold fault/fill shear zones, as well as, the Golden Anchor gold zone further to the northeast. The HDZ is also host to the zinc and copper rich (+/- Ag and Au) Lochinvar massive sulphide horizon which is located in the footwall rocks of the Golden Anchor gold vein system.
Immediately east of the Golden Anchor/Lochinvar mineralization the HDZ is abruptly truncated by a prominent north/south trending fault zone. On the eastside of the north/south fault zone the geology changes polarity from the regional northeast trending to a north/south trend around a NE plunging antiform. Airborne magnetics surveys also highlight the change in the geological trend. Limited exploration on the eastside of the fault zone indicates that the HDZ may be transposed along the north south trend now known as the Catchers Pond/Beetle Pond Zone (CBZ).
Evidence for HDZ style gold mineralization along the CBZ is supported by limited exploration in the area which included several diamond drill holes along with geochemical and geophysical surveys. However, it should be noted that the historical ground based grid surveys were not orientated in the optimum direction that would effectively have tested the north/south CBZ for any potential mineralization that may parallel mineralized structures/stratigraphy similar to those occurring in the HDZ. Several diamond drill holes were completed in the CDZ near Beetle Pond. A mappable antiformal fold structure occurs in the Beetle Pond area and the drill holes also reported zinc rich semi-massive to massive stringer style mineralization hosted in highly altered felsic volcanics of the Catchers Pond Group. The Catchers Pond Group is host to several “Buchan’s Style” VMS exploration targets, including the Lochinvar zinc rich deposit. The fold nose may host thickened sequences of massive sulphides or concentrate gold rich veins similar to Lochinvar or Hammerdown.
Several drill holes on the east side of the north/south fault immediately east of the Golden Anchor zone intersected several quartz/sulphide veins assaying up to 6 g/t gold, similar to Hammerdown style veins. These results demonstrate clearly that the gold bearing Hammerdown Deformation Zone crosses the strong fault, and extends for several kilometres with gold vein potential. This drilling has never been followed up.
Soil sampling in the Beetle Pond area over the antiformal fold, highlighted a large geochemical anomaly defined by highly anomalous soil and lithogeochemical results for gold and base metals, measuring in excess of 1.5 km in diameter.
Future exploration focus in the CBZ will be given to defining Hammerdown/Golden Anchor style gold veins hosted in sheared fault/fill zones, along with deep exploration to determine if a deeply buried, massive sulphide deposit exists associated with the existing widespread, visually impressive, alteration and disseminated sulphide mineralization identified in the area of Beetle Pond within the CBZ. Detailed ground geophysical surveys will be completed over the eastern portion of the CBZ to outline drill targets.
