The Something Good showing is located at 900 metres elevation on the west side of Keremeos Creek, 1.5 kilometres south-southwest of Olalla, British Columbia. The showing was originally covered by the Something Good (Lot 1451), Great Eastern (Lot 3437), Silent Friend (Lot 3439), Lisey D Fraction (Lot 3441) and AC Fractional claims.

In 1899, the Something Good and Great Eastern claims were owned by Neden and Bullock-Webster and a 24-metre tunnel was developed. The Something Good claim (Lot 1451) was Crown granted in 1900 and is now reverted. The adjacent Great Eastern claim was Crown granted in 1906 to S. Mangott and L.W. Shatford and is also now reverted. In 1932, the claims were transferred to W.C. McDougall. Olalla Gold Mines Ltd. was incorporated in 1935 and acquired the Something Good and Sunrise (082ESW015) properties. In 1936, the company name changed to Hedley Crest Mines Ltd. Gold Valley Mines Ltd. acquired 19 claims and fractions in 1936, which included the Something Good. The workings consisted of adits Nos. 1 and 2 by this time. In 1945, Hedley Monarch Gold Mines Ltd. began to re-open and explore the Something Good showing as part of an acquisition of 72 claims and fractions. Since the 1980s the claims have been owned by G. Crooker and most recent exploration work conducted by Goldcliff Resources Corp. A 1997 work program by Goldcliff consisted of constructing a new road to the Cliff zone, conducting trenching and drilling on the Cliff zone and drilling on the Copper King zone, and a soil geochemical survey on the Cliff

and Something Good zones. The 1997 work program also consisted of sealing the portals of two adits, rehabilitating 6.0 kilometres of old road and collecting 21 rock samples from the Sweetner vein, Powder breccia and Something Good shear zone. This rock sampling gave weakly to moderately anomalous gold values in the 100 to 1100 ppb on the Sweetner vein and Powder breccia. Results from the Something Good shear zone were strongly anomalous with gold values up to 21.98 grams per tonne over 0.85 metre (Assessment Report 25033).

At the Something Good occurrence, a carbonate shear and breccia zone occur in argillaceous and cherty sediments near the margin of MIddle Jurassic Olalla pluton. The zone strikes 235 to 255 degrees. The margin of the pluton is composed of pyroxenite. Calcite, quartz and pyrite occur within the zone.

Three adits were driven on the carbonate shear and breccia zone between 1936 and 1937. The No. 1 (Something Good) adit, at 775 metres elevation, was driven for 107 metres along the footwall of the shear zone. The first 33.5 metres of the adit followed a well defined breccia zone. The shear zone is about 1.2 metres wide in the adit and widens upward to about 4.87 metres, 12 metres above the adit. Minor quartz also occurs in the breccia at this point. Narrow quartz stringers, up to 7.6 centimetres wide, diagonally cut the shear zone. The stringers strike 300 degrees. Another 15 metres higher in elevation, the shear zone is seen as a branching structure of sheared and shattered rock. Argillite and quartzite fragments are cemented with calcite, which also contains small amounts of disseminated pyrite. Fragments are dominantly coarse sand-sized and occasional attain walnut size. From 33 metres to the face of the adit, the footwall is accompanied by 2 to 30 centimetres of graphitic fault gouge.

Samples taken by M.S. Hedley in 1937 ranged from 1.71 grams per tonne gold over 1.37 metres to 75.43 grams per tonne gold over 28 centimetres (Assessment Report 19963). The highest gold values are restricted to the section of breccia where there is quartz veins associated with calcite cementation. The end of the higher values is coincident with a poorly defined crosscutting shear. Beyond this point the graphitic shear contained negligible gold values. A 50.8-centimetre chip sample taken in 1932, thought to be from 3 metres above the No. 1 adit, yielded 222.17 grams per tonne gold and 41.14 grams per tonne silver (Minister of Mines Annual Report 1932, page 138). Several samples were taken from the breccia zone in 1993. Grab sample 92C-10 from rusty fault gouge in the breccia zone, yielded 1.71 grams per tonne gold, 0.42 per cent arsenic, 0.07 per cent copper and 0.02 per cent platinum (Assessment Report 22882).

The No. 2 adit, at 753 metres elevation, was driven 46 metres westward, approximately parallel to the No. 1 adit. The adit intersected mainly pyroxenite but the last 6.1 metres intersected cherty sediments. Six holes were drilled southwesterly from the face of the No. 2 adit. The holes were drilled along the strike of the breccia zone in the No. 1 adit but failed to disclose information on the downward extension of the breccia zone. Anomalous gold values were sporadic.

The No. 3 adit, at 714 metres elevation, was driven 117 metres in pyroxenite. Negligible gold values were also reported. Three drillholes were also drilled from the face of the No. 3 adit in an attempt to intersect the breccia zone at depth. The hole intersected mainly argillite and quartzite with minor limestone and pyroxenite. No anomalous gold intersections were found.

A hornfels zone was discovered on the south-central portion of the Great Western claim in 1986. The hornfels occurs along the sheared contact between pyroxenite of the Olalla stock and metasediments of the Old Tom Formation. Chalcopyrite, pyrite, malachite and azurite were observed in the hornfelsed zone. Grab sample C-88-4 from this zone yielded 0.01 gram per tonne gold, 12.1 grams per tonne silver, 0.99 per cent copper and 0.11 per cent zinc (Assessment Report 17648).

A sample taken across 0.84 metre of the vein assayed 21.98 grams per tonne gold and 9.00 grams per tonne silver (George Cross News Letter No.84, 1997).
