The Goosly Lake intrusion, 4.8 kilometres east of Goosly Lake, is a quadrate body, approximately 3.2 kilometres on a side, which cuts Early Mesozoic lavas and pyroclastic rocks with some argillite. The intrusion seems to be the source of the Eocene Goosly Lake volcanics comprised of trachyandesite and trachyte. The hosting volcanics are part of the Lower Cretaceous Skeena Group which is comprised of a mixed assemblage of sediments and felsic volcanic fragmental rocks with intercalated shale, massive rhyolite lava, and conglomerate (Bulletin 78, Figure 1).

The alkaline intrusive ranges from gabbro to syenomonzonite, consisting of 65 to 80 per cent plagioclase, commonly occurring as large bladed phenocrysts, 5 to 20 per cent augite as small rounded grains or long prismatic phenocrysts, and accessory biotite, apatite and magnetite. Interstitial feldspar and traces of quartz are found in the more acidic varieties. The gabbroic phases are enriched with pyroxene and contain calcite and chlorite pseudomorphs after olivine with accessory feldspathoid minerals.

The lavas, believed to be associated with the stocks, contain the same minerals with the addition of occasional hornblende, but in somewhat different proportions. Parts of the volcanic sections are unusually massive suggesting very thick lava flows or possibly sills.

Several significant mineral occurrences are associated with the alkaline rocks of the Goosly Lake area. Approximately 3.2 kilometres east of Goosly Lake, at the east end of the intrusive belt, the Equity Silver property (093L 001) hosts a replacement sulphide deposit consisting of lenses of pyrite-chalcopyrite-tetrahedrite located adjacent to the alkaline stock. A rare iron phosphate mineral, scorzalite is associated with the mineralization on this property.

In 1969, an analysis of the syenomonzonite, located 6.4 kilometres east of Goosly Lake, showed 2.6 per cent ilmenite (Geology, Exploration and Mining in British Columbia 1969, page 148).

In 2012, ZTEM aeromagnetic surveying completed on behalf of Finlay Minerals covered the Dina (093L 313) and Goosly Lake titanium showing (093L 263).

In 2013, the exploration program of Finlay Minerals Ltd on their Silver Hope property consisted in part of ground checking five airborne ZTEM resistivity lows (Anomalies 1 to 5) and four other areas of interest (Anomaly A to D). Finlay visited the reported location of the Dina MINFILE occurrence which lies a short distance northeast of the Anomaly B area and less than 400 metres west from the (highly generalized) MINFILE location of the Goosly Lake titanium location. Rocks found in overburden and in streams indicate that most of Anomaly B is underlain by Paleocene volcanics, although smaller areas with the Cretaceous rocks may also be present.
