Abstract: The first clue to the presence of possible diamond-bearing source rocks in northern Alberta was the discovery of a perfect octahedral diamond, estimated at about 0.83 carats in weight, by farm worker Einar Opdahl during 1958 in the Evansburg area of west-central Alberta. Since the Opdahl diamond, no new diamond finds were reported in northern Alberta until the 1990s, when several occurrences of alluvial diamond and diamondiferous kimberlite were discovered.

Abstract:
The first clue to the presence of possible diamond-bearing source rocks in northern Alberta was the discovery
of a perfect octahedral diamond, estimated at about 0.83 carats in weight, by farm worker Einar Opdahl
during 1958 in the Evansburg area of west-central Alberta. Since the Opdahl diamond, no new diamond finds
were reported in northern Alberta until the 1990s, when several occurrences of alluvial diamond and
diamondiferous kimberlite were discovered.
Purpose:
The purpose of the digital dataset is to make publicly available two Alberta diamond datasets: 1. Confirmed
and rumoured occurrences of diamond in alluvium This dataset includes information on 22 occurrences of
diamond in alluvium. In the infancy stages of Canada's ongoing diamond play, the current focus on alluvial
diamonds is to treat them like indicator-minerals; that is, alluvial diamonds occur proximal to, or have
been relocated down-ice from diamondiferous source rocks. If that is the case, then diamond explorers take
note because in northern Alberta some alluvial diamond occurrences cannot be related to known clusters of
diamondiferous kimberlite. These alluvial diamonds of uncertain origin include: - the Caribou diamond, which
is north (up-ice) of the Buffalo Head Hills kimberlite field; - the Whitecourt diamonds, which are separated
from the Buffalo Head Hills kimberlite field by a physical boundary of younger Swan Hills Tertiary gravels;
- the Calling lake diamond, which is in an area of known indicator-mineral anomalies with unique chemistries
that favour the future discovery of a new diamondiferous kimberlite field in northeastern Alberta; and -
finally, 23 micro- (<0.5 mm) and macro- (>0.5 mm) diamonds, including a clear 0.4 mm octahedral-shaped
diamond, which were recovered north of Hinton, remain unexplained and may be of local origin. Knowledge
about these alluvial diamond occurrences may, one day, help to locate a bedrock diamond deposit in Alberta,
but their presence also poses an important question: Can Alberta alluvium contain economic concentrations of
diamonds? 2. Occurrences of diamond in kimberlite/ultramafic rocks This dataset includes information on
diamond occurrences from 32 host rock sources. To the end of 2006, 48 ultrabasic to kimberlite pipes have
been discovered in three separate areas of northern Alberta, with 2 closely spaced pipes at Mountain Lake,
38 pipes at Buffalo Head Hills and 8 pipes at Birch Mountains. The best diamond results to date are from the
Buffalo Head Hills kimberlite field, where 26 of the 38 pipes contain diamond. Mini-bulk samples from 3 of
the 38 Buffalo Head Hills kimberlite occurrences have estimated diamond grades that range from 12 carats per
hundred tonnes (cpht) to 55 cpht in kimberlite K252, with a particular breccia from this occurrence having
an estimated grade of 85 cpht.

Evaluation method description:
The information compiled in the spreadsheet was obtained from the results of previous work that had been
conducted throughout the province of Alberta. Within the dataset there are two main worksheets, one for
diamonds that had been reported in the alluvium and the other for diamonds that had been found in host
rocks. In both of the worksheets several generic fields were captured describing characteristics of the
diamonds reported, sample information, location information, etc. There are some fields within the two
worksheets that were not captured and were either marked by leaving a cell blank or simply by using N/A.

Measure description:
In terms of validating the data simple checks were carried out to make sure that basic characteristics of
the dataset were accurate/intact. Since the dataset was fairly small the checks that were ran were
fairly general and they resulted in a few minor edits that included spelling changes within the field
names.

Description:
The Alberta Diamond Occurrences dataset consits two worksheets within a excel spreadsheet containing
data and information about the confirmed and rumored occurrences of diamond in alluvium and
occurrences of diamond in kimberlite/ultramafic rocks.
The data was later normalized and transferred into a database for the purpose of creating metadata. It
should be noted that when the data was put into a database the appearance of the data changed but
the nature of data remained intact.
