The Art-DL property is located approximately 75 kilometres northeast of 100 Mile House and 25 kilometres southeast of Boss Mountain molybdenum mine, in the south-central Cariboo region of BC, Canada. The property is composed of two gold prospects. The DL prospect is centred on an adit (a tunnel with only one entrance), which dates back to the 1880s. Rock samples have returned up to 42.9 grams per tonne gold and 34.7 grams per tonne silver over 1 metre. The Art prospect is located approximately 2 kilometres to the west.

The key geological aspect of the Art and DL prospects is that they cover a portion of the Eureka Thrust, a continental-scale fault between the Quesnel terrane, an Upper Triassic–Lower Jurassic volcanic island arc to the west, and the older continental shelf sediments composed of the Paleozoic Snowshoe Formation to the east. The Thunder Ridge prospect, located 1.5 kilometres to the south, is within the same geology; drilling has discovered multiple zones containing positive to significant gold. The geological setting of the DL prospect is also similar to the Spanish Mountain and Frasergold deposits, located 40 to 100 kilometres to the north.

The DL adit zone consists of a gently plunging saddle reef-style quartz vein, hosted by black graphitic, porphyroblastic or 'knotted’ phyllite. Numerous quartz veins occur that are structurally controlled and refolded, and a minimum of two generations of quartz and quartz-carbonate veins have been noted. Northwest of the adit, fine-grained dykes of possible latite to aplite composition contain pyrite, trace arsenopyrite and stibnite (arsenic and antimony sulphides, respectively).

Since the adit was located and claims staked in 1987, the property has seen intermittent and generally localized exploration through prospecting and geochemical, geological and geophysical surveys. In 2001, six shallow holes were drilled, with one hole containing a positive gold anomaly on the Art prospect and another containing 3 metres of 1.07 grams per tonne gold at the top of the hole southwest of the DL adit.

Between 2005 and 2010, Happy Creek conducted systematic prospecting, rock, stream sediment and soil geochemical surveys and geological mapping. Soil geochemical surveys and rock sampling have outlined multiple areas containing positive anomalies of silver and gold over a 2-kilometre distance. Five drill holes were completed by Happy Creek in 2010 that tested several geochemical anomalies, including ones beneath the DL adit. The drilling did not intersect significant gold values and the orientation and extent of the large gold-bearing quartz vein in the adit remains unknown. To the south of the adit, one drill hole returned 72.5 metres of 4 grams per tonne silver, including 20 metres of 8.5 grams per tonne silver and up to 0.28 gram per tonne gold, which is of exploration interest and remains open in extent. Several positive anomalies of up to 1.8 grams per tonne gold in soil also occur that require further investigation, and much of the property remains unexplored.

In 2011, Happy Creek Minerals performed prospecting and rock, stream sediment and systematic soil geochemical surveys that expanded previous surveys covering portions of the Hen and Art-DL properties. In total, 708 soil, 20 stream sediment (silt) and 21 rock samples were collected. Rock samples contained from less than 0.01 to 1.04 grams per tonne gold, less than 0.01 to 17.7 grams per tonne silver and 0.00028 to 0.13 per cent copper. Soil samples returned values from trace to 0.1 gram per tonne gold, 2.1 grams per tonne silver, 0.048 per cent copper, 0.00169 per cent molybdenum and 0.0627 per cent zinc. Silt samples returned from trace to 0.03 gram per tonne gold, 0.6 gram per tonne silver, 0.0193 per cent copper, 0.00116 per cent molybdenum and 0.018 per cent zinc (V STOCKWATCH, February 13, 2012).
