Introduction
A regional sampling program for alluvial gold in the Cypress Hills Formation was carried out in southwest Saskatchewan in 1997. This report presents the results of that program and outlines the economic potential of the region for gold paleoplacer deposits.
The project area covers parts of NTS map sheets 72F, 72G, 72J, and 72K and encompasses the main outcrop areas of the Cypress Hills Formation in southwest Saskatchewan. The region covers about 12 000 km2 (Figure 1).
The Cypress Hills Formation is an Upper Miocene to Eocene fluviatile sequence of poorly consolidated conglomerates, gravels, and sands that form two main plateau-like outcrop areas in southwest Saskatchewan: an easterly block that lies south and west of Swift Current; and a dissected western block that extends into southeast Alberta. The formation has a maximum thickness of about 80 m and averages 38 m. Regionally, the base of the formation lies on an erosion surface that dips east at 3.8 m per kilometre (Vonhof, 1969).

Background and Previous Work
In 1990, a regional geochemical survey was carried out by the Saskatchewan Research Council (SRC) and Cameco Corporation over an area of approximately 64 000 km2 in southwest Saskatchewan (Simpson, 1991). The main objective was to map kimberlite indicator minerals in the surficial deposits, but gold grains were also recovered from the heavy mineral concentrates. Approximately one sample per 300 km2 was collected, primarily from glacial and fluvioglacial sands and gravels in road cuts and gravel pits. In addition, a few samples of bedrock were collected. About 25 kg of <5 mm material was collected at each site. Heavy mineral concentrates were obtained using screens, shaker tables, and magnetic separation. Gold grains were panned from the concentrates and were counted, described, and weighed.
A number of anomalous (greater than the background concentration of 5 to 10 ppb) gold values were found in glacial deposits of the region, but by far the largest anomaly was obtained from a bedrock sample of the Cypress Hills Formation taken from a small quarry about 4 km west of the hamlet of Simmie (Figures 2 and 3) in the west half of Section 32, Township 11, Range 16W3. This sample produced 468 grains of gold estimated to weigh 3744 µg. Although several sample sites with diamond indicator minerals were re-sampled, the gold anomaly was not investigated further by SRC or Cameco.
In March 1994, a mineral disposition consisting of two half sections (east half of Section 32 and west half of Section 33) was recorded just east of the geochemical anomaly, but was allowed to lapse and no assessment work was submitted. In May 1996, the geochemical anomaly (named “the Simmie showing”) was staked by Lemar Resources. In June 1997, they optioned the property to Consolidated Pine Channel Gold Corporation who undertook bulk sampling of the discovery quarry. Four 22 kg channel samples were taken from the face of the quarry and processed at the Saskatchewan Research Council’s Geochemical Laboratory. Gold content of these samples ranged from 686 to 1554 grains of gold, and calculated grades ranged from 132 to 258 ppb (SIR Assessment File 72F16-NE-0001).
In the summer of 1997, a regional sampling program of the Cypress Hills Formation was carried out by Consolidated Pine Channel under the direction of the author, acting as consultant to the company. When results of the survey were obtained, a number of claims were staked to cover the main anomalies, but the claims were allowed to lapse in 1999 and no further work was done. At the same time, Consolidated Pine Channel dropped their option on the Simmie claim. As of March 2003, the Simmie showing was covered by a small claim of 32 ha held by Lemar Resources. Consolidated Pine Channel has graciously permitted the writer to include the results of the 1997 regional sampling program in this report.

Sample Collection
Sampling took place in three stages between May and October 1997. Ninety-two samples (DP7-01 to DP7-92) were collected from the eastern part of the region (map sheets 72J-3, -4, and -5; 72G-13; 72F-16; and 72K-1). In addition, 48 samples were collected from the western part of the region (MM7-07 to MM7-17, MM7-20 to MM7-49, and MM7-57 to MM7-63) from NTS areas 72F-10, -11, -12, -14, and -15.
After results of the initial sampling were obtained, several sites, where anomalous values were obtained were re-sampled (DP7-93 to DP7-108).
Samples were collected from road cuts, quarries and outcrops. Sample spacing was uneven, particularly in the eastern part of the region, due to the erratic distribution of outcrops and exposures. Where possible, the largest and thickest sections of the Cypress Hills Formation were sampled.
About 7 kg of screened (<4 mm) sandy matrix of the conglomerate was collected at each locality. In thick sections, samples were obtained by channeling the matrix from top to bottom (Figure 4). Samples taken from shallow road cuts and small outcrops were essentially grab samples (Figure 5). In a few cases, samples were taken from shallow, hand-dug pits where bedrock was covered by thin drift and soil.
Sampling details are listed in Appendix 1. Geographic locations (Section, Township, and Range) and elevations were determined from field maps and field notes of the field parties. Latitude and longitude were estimated by digitizing from the paper field maps.

Sample Processing
All samples collected in the field were processed at Saskatchewan Research Council’s Geochemical Laboratory. Samples were weighed and screened to <1.7 mm. The coarse material was rejected. The weight of the <1.7 mm material was recorded and the sample was passed over a shaker table to separate the light and heavy particles. Samples with anomalous quantities of gold were subjected to several runs.
The heavy mineral concentrate from the shaker table was weighed then wet sieved to <1.0 mm and magnetic particles were removed from the <1.0 mm fraction with a hand magnet. The non-magnetic material was then passed through a “Magstream Separator” and the >3.9 g/cm3 specific gravity material was isolated.
Gold grains were removed from the heavy fraction with a “Mosley Superpanner” and grains were documented and counted. Gold concentration was then determined by fire assay. Gold grain counts were not carried out for the samples bearing the prefix “MM” (Appendix 1).
Saskatchewan Geological Survey 5 Open File Report 2004-1
Results
Gold Content and Distribution Analytical results are summarized in Appendix 1. Gold grain counts range from 0 to 2770 and gold concentrations by fire assay range from 0.1 ppb to 274.5 ppb. Statistical treatment of the analytical data was not carried out due to the small sample population, but anomalous values are readily apparent from visual inspection of the data.
Most of the samples (78%) contained less than 10 ppb Au, a value that is taken to represent the regional background. Concentrations of 10 ppb and greater are considered to be anomalous and are arbitrarily divided into weak (10 to 20 ppb), moderate (21 to 50 ppb), strong (51 to 100 ppb), and very strong (>100 ppb) anomalies. There are 33 anomalous samples in total.
The regional distribution of gold values is shown in Figure 6. There are 28 anomalies, including the strongest in NTS map sheet 72F-16. Several of these samples were in and near the Simmie showing discovery quarry. Sample DP7-01 is from the lower conglomerate in the quarry and returned 163 grains of gold assaying 179.3 ppb. This is compatible with the grades in channel-samples in the showing (SIR Assessment File 72F16-NE-0001).
The other anomalous samples in 72F-16 form an east-trending rectangular zone approximately 10 km by 5 km, roughly coincident with the current drainage basin of Swift Current Creek, which is inferred to be coincident with an ancestral river system active since the beginning of the Tertiary.
Of the anomalous samples in the “DP” group, all but five are from the rectangular zone described above. The five anomalies outside of the rectangle are only moderate in amplitude with gold grain counts ranging from 20 to 45 and assays ranging from 13.0 to 30.5 ppb. Samples DP7-65 and -79 (20.0 and 30.5 ppb respectively) occur in NTS map sheet 72J-4 on the north flank of the Swift Current block of the Cypress Hills Formation. Both samples are from within a few kilometres of the Swift Current Creek drainage basin. Samples DP7-71 and -72 (30.1 and 13.0 ppb respectively) in NTS 72K-1 also lie on the north flank of the Swift Current block and are close to Swift Current Creek.
Sample DP7-83 (20.5 ppb) is a single anomaly in NTS 72G-13 near the south edge of the Swift Current block. Two check samples (DP7-107 and -108) taken from this locality were not anomalous (1.1 and 3.6 ppb).
The only anomalous samples (MM7-16 and -26) discovered during the sampling of the western part of the region “MM” group of samples) are in NTS map sheet 72F-15. Sample MM7-16 contains only 21.1 ppb Au but MM7-26 assayed at 93.5 ppb Au and is considered significant.
Gold Grain Documentation Gold grain documentation consists of measuring the length and width of each grain in microns and describing the shape as “I” - irregular, “A” - abraded, or “A/I” - transitional between the two. Irregular grains are pitted, have several protrusions, and may be curled. Abraded grains are more leaf shaped and rounded and lack pitted surfaces. Irregular grains are interpreted as having been transported for a short distance, whereas rounded grains imply a more distant source. In richer samples, only 50 grains are examined and the total number is estimated. Complete gold grain data are contained in the SRC assay reports which are archived and available for review at Saskatchewan Industry and Resources in Regina.
Most of the gold grains are rectangular with dimensions ranging from 20 to 580 microns, although the majority of the grains fall within the 100 to 200 micron range. Paradoxically, the largest grains are from only moderately anomalous samples. Sample DP7-40 contains 44 grains (13.8 ppb) and includes one grain measuring 260 microns by 500 microns. The largest grain discovered (200 microns by 580 microns) occurs in sample DP7-71 which only contains a total of 31 grains (30.1 ppb).

Most samples contain a mixture of all three morphologies, although a few samples have predominately rounded grains and a few contain mainly irregular grains (Figure 7).

Economic Potential - Discussion
The three main parameters that should be addressed in any discussion of the economic potential of a region for paleoplacer deposits of gold are: 1) depositional environment, 2) source and origin of the alluvial gold, and 3) grade/tonnage possibilities.
Depositional Environment Detailed studies of the Cypress Hills Formation by Leckie and Cheel (1989) indicate that the Tertiary gravels of southwest Saskatchewan were deposited from a north-to northeast-flowing, braided river system that originated in the Sweetgrass Hills, Bearpaw Mountains, and Little Rocky Mountains of north-central Montana (Figure 8).
Figure 8 - Paleogeography of the Cypress Hills Formation.
Saskatchewan Geological Survey 9 Open File Report 2004-1
The Cypress Hills Formation in the western part of the region is coarse grained and lacks finer sediments (Figure 9). In contrast, outcrops in the east and northeast (Swift Current block) represent deposits of small channels and interchannel areas that contained intermittent lakes and mudflats.
The contrasting depositional environments may explain the regional distribution of alluvial gold. The relative paucity of gold in the western part of the region is probably due to the higher energy level of the rivers such that gold was held in suspension and not deposited. The lower energy environment of the drainage system in the east permitted the gold grains to fall out of suspension to form a placer deposits.
Source of Alluvial Gold The relatively large grain size and the abundance of irregularly shaped grains suggest a local gold source. There are, however, no known gold-bearing source rocks in the vicinity. A paleogeographic reconstruction of the region in Tertiary times by Kjarsgaard (1995), suggested that the Tertiary gravels forming the eastern part of the region, in particular the Swift Current block, were largely derived from the Bearpaw Mountains and Little Rocky Mountains (Figure 8). As the latter area is rich in vein gold deposits, it seems likely that the alluvial gold in the Cypress Hills
Formation was derived from that area of north-central Montana.
Grade/Tonnage Considerations To date, Phanerozoic paleoplacer deposits of gold in rocks have not been considered a high priority exploration target because of the notion that they are too small or of insufficient grade for full-scale commercial production. Deposits in the Cypress Hills Formation could prove an exception because gold is widely distributed, particularly in the Swift Current block, with numerous highly anomalous concentrations locally. At the Simmie showing, gold is widely and evenly disseminated with grades ranging from 132 to 258 ppb (SIR Assessment File 72F16-NE-0001). This compares favourably with modern day placers with minimum economic grades of 150 to 200 ppb. The quarry face at the Simmie showing exposes a section of mineralized Cypress Hills Formation 8 m thick and 150 m long (Figure 2). Assuming that this represents a cross-section of the ancient drainage system, and that mineralization extends for several kilometres along its length, the deposit could be in the order of several million tonnes.
At the Simmie showing, it is not known whether gold values increase towards the underlying unconformity with the Bearpaw shales. In placer districts, grade generally increases towards the base of the formation and, moreover, rich “paystreaks” of these districts are generally at, or close to, the bedrock surface beneath the detrital sediments.
Production of gold, as a by-product of aggregate quarrying of Tertiary formations in Alberta (including the stratigraphic equivalent of the Cypress Hills Formation) has been described by Edwards et al. (1994). It is reported that the processed sand and gravel contains the equivalent of 50 ounces of gold for every 100 000 tonnes of material.

Summary and Conclusions
1) Regional sampling of the Upper Miocene to Eocene Cypress Hills Formation, in southwest Saskatchewan, shows that in the eastern part of the sampled area, particularly in the Swift Current block, the formation contains widespread alluvial gold.
2) The Simmie showing, discovered prior to the regional program, has consistent values ranging from 132 to 258 ppb Au and could be part of a large, low-grade deposit. Further exploration of the deposit could disclose higher grades and “paystreaks” closer to the base of the gravels.
3) Several other anomalies in the Swift Current block should be sampled in detail to determine the lateral extent of the mineralization.
4) In view of the irregular spacing of the samples in the Swift Current block, a program of fill-in reconnaissance sampling might be rewarding. Shallow trenching would be necessary in places to attain complete coverage.
5) Gold grains are relatively coarse and irregular in shape suggesting a local source, but paleogeographic interpretation suggests that the source was the vein gold deposits of the Little Rocky Mountains in north-central Montana.
6) The westerly outcrop areas of the Cypress Hills Formation contain background concentrations of alluvial gold and are not considered to be prospective.
