Exploration History

Prior to 1938, the property was owned by Boyden Red Lake Gold Mines, Ltd. The company's charter was cancelled in 1938. By 1959, the property had been staked by Rockcroft Explorations Ltd. In the late 1920s, surface work was performed on the property. Work was carried out in 1958, and consisted of four drill holes, totalling 61 m. In 1959, a magnetometer survey of the property, and I.P. and EM surveys of parts of the property were completed. As well, an extensive geological survey was performed that year. 2019-2021: Pacton Gold completed across the Red Lake Gold Project that includes Boyden a high-resolution magnetic, VLF, EM and Lidar survey and soil sampling. Holes PAC-19-001 to 008 were targeting Boyden. The Boyden quartz veins were stripped and channel sampled.

Lithology Comments

Nov 03, 2014 (K R Kettles) - The mafic and intermediate volcanic rocks are commonly porphyritic with large tabular plagioclase phenocrysts (turkey track in appearance). Pillow structures have been noted. Thin bands of interflow tuffs occur within the volcanic flows. These units are thinly bedded, with individual beds rarely greater than 15 cm in width. The felsic vocanics in the area change from fine grained tuffs to coarse breccias southward. The felsic tuffs exhibit faint bedding, with beds up to 10 cm in thickness. Coarse breccias occur in the southwest corner of the property, and consist of large angular fragments set in a fine grained matrix. At least three types of intrusions are present in the area. The gabbroic intrusions are closlely associated with the mafic and intermediate volcanics. Small quartz diorite dikes are also abundant in this area. Quartz porphyry and quartz feldspar porphyry dikes are also present in the area, and are closely associated with the interflow tuff units. Potassic metasomatism has occured where the volcanics are sheared.

Mineralization Comments

Nov 03, 2014 (K R Kettles) - A 15 cm chip sample taken from the main showing reportedly returned an assay of 1.04 oz/ton (35.656 g/tonne) Au. Samples collected from trenches in 1986-87 returned balues up to 2.36 oz/t Au and 11.56 oz/t Ag. The showing consists of a zone of quartz veining and silicification in altered intermediate volcanic rocks. The zone striking E-W and is cut by quartz diorite and granite dikes. The silicified rocks contain quartz eyes, and may be quartz porphyry. High gold values were returned from dark quartz, containing pyrite, galena and sphalerite.


May 12, 2023 (Paul Malegus) - Channel sampling in 2019 by Pacton Gold returned results of 101.3 g/t, 33.9 g/t, 31.6 g/t and 27.6 g/t Au.



Alteration Comments

Dec 07, 2005 (K R Kettles) - The interflow tuff units have been silicified and mineralized with pyrite where adjacent to quartz porphyry dikes.
