Alberta's most valuable mineral by tonnage and dollars — and the one most often sterilized by the cities that need it.
Roughly 55–75 Mt of sand and gravel a year (12–15 t per person) come from several hundred pits, with the Susan Lake pit near Fort McMurray setting a Canadian record at 11.8 Mt in 2008. Preglacial channel gravels and glaciofluvial outwash near Edmonton and Calgary are being depleted or built over, so haul distance increasingly sets the price.

GEOLOGY: WHAT MAKES A DEPOSIT MORE LIKELY
Buried preglacial channel gravels and glacial outwash; quality depends on clast lithology (quartzite / chert vs shale).
Host formations
Empress Formation preglacial gravels · Glaciofluvial outwash · Modern river terraces
Depth range
0–30 m
Favourable conditions
Thick clean gravel with low shale and deleterious content
Within 50 km of demand centres or oil sands mines
Thin overburden and above the water table
Not sterilized by urban growth or wetlands
