234 GEOLOGICAL RECONNAISSANCE OF THE DOMINICAN REPUBLIC. 



RESULTS OF SAMPLING. 



Samples were taken from all accessible parts of the hill (see Nos. 1-14 

 inclusive, on PI. XXII) , and particularly from the parts that showed best evi- 

 dence of valuable mineralization, so that the mean of the samples prob- 

 ably shows a considerably higher tenor than the average. The following 

 notes describe the samples taken: 



Prospect pits sampled by Ferguson. 



Sample 1. Grab sample from outcrops extending N. 45° W. across small outlying hill 

 for a distance of 360 meters. Practically unaltered serpentine at the base; cut at the 

 summit by small quartz veinlets containing traces of garnierite. Assay result: Nickel, 

 0.65 per cent. 



Sample 2. Grab sample from outcrops extending N. 45° W. up main hill to 104-meter 

 contour for a distance 120 meters. In serpentine, slightly veined. Assay result: 

 Nickel, 0.29 per cent. 



Sample 3. Grab sample from outcrops extending 190 meters to crest of ridge. Ser- 

 pentine with rare quartz veinlets. Assay result: Nickel, 0.29 per cent. 



Sample 4. Grab sample from outcrops extending 270 meters along crest of ridge. 

 Same type of materials as No. 3. Assay result: Nickel, 0.41 per cent. 



Sample 5. Continuation of No. 4 for a distance of 140 meters. Type of material simi- 

 lar. Assay result: Nickel, 0.43 per cent. 



Sample 6. Open cut at base of hill near camp. Sample along sides of cut for 6 meters 

 N. 85° W. No visible garnierite, but slight quartz veining and weathered serpentine. 

 Assay result: Nickel, 0.36 per cent. 



Sample 7. Small open cut on trail at 124-meter contour, 6 meter face. Weathered 

 serpentine. Assay result: Nickel, 1.13 per cent. 



Sample 8. Shallow cut along 198-meter contour for distance of 195 meters. Weathered 

 serpentine with rare quartz and garnierite. Assay result: Nickel, 1.05 per cent. 



Sample 9. Open cut 50 meters long from south end of No. 8 to crest of ridge. Serpen - 

 time with many small quartz stringers and a httle garnierite. Assay result: Nickel, 

 0.55 per cent. 



Sample 10. Small open cut just below crest of ridge on east side, 18 meters long. 

 Serpentine with quartz and garnierite. Assay result: Nickel, 1.75 per cent. 



Sample 11. Open cut across top of ridge, 25 meters long. Serpentine honeycombed 

 with small quartz veins in places, with good showing of garnierite. Assay result: 

 Nickel, 2.09 per cent. 



Sample 12. Small pits along crest of hill, in two lines, 5 meters apart and 1 meter deep, 

 many not reaching bedrock. Samples taken from material on dumps, consisting of 

 weathering serpentine and quartz, for a distance of 80 meters. Assay result: Nickel, 

 3.01 per cent. 



Sample 13. Northward continuation of same line of pits, most of them, however, not 

 reaching bedrock. Distance, 240 meters. Similar material. Assay result: Nickel, 1.24 

 per cent. 



Sample 14. Line of similar pits southward from No. 11, most of them reaching bedrock. 

 Distance, 220 meters. Similar material. Assay result: Nickel, 1.29 per cent. 



Samples from shaft on summit of hill taken by Condit. 



Samples 15 to 22. The samples taken below the surface include Nos. 15 to 19, 



selected from the ore dump, and Nos. 20 to 22, taken from the deeper part of the shaft. 



The material from the deepest part of the shaft consists of dark -green serpentine, veined 



by white, soft, amorphous material, which is regarded by the mine foreman as the
