Hole-Averaged Silver Equivalent Values (Based on Certified Silver and Gold Assays) from Drill Holes on the West Zone of Rome's Don Luis Property
30.11.2011 | Marketwire
SURREY, Nov. 30, 2011 - Rome Resources Ltd. (TSX VENTURE:RMR) (FRANKFURT:33R) is pleased to announce hole-averaged silver equivalent grades from certified gold and silver assays in drill holes (DLS10DD01 & 2 and DLS11RC001 to 064) on the West Zone of the Don Luis Greisen-Porphyry Silver-Gold-Tungsten Property, Sonora, Mexico (all holes in the West Zone are located in Fig. A1). Composed results from the first six reverse circulation (RC) holes were reported in News Release #06, May 5th 2011, and correspondingly detailed data for RC holes 001 to 024 were announced in News Release #08, August 10th 2011. This report presents hole-averaged assay data for all holes currently completed in the West Zone. Certified silver and gold grades from Pioneer Laboratories Inc. (Richmond, BC, Canada) in Table A1 were used to calculate the hole-averages of silver equivalent grades (on a 1 silver to 40 gold ratio)¸ which are presented in the right hand column of Table A1.The West Zone of the Don Luis Property has porphyry-style, open-pit tonnage potential. The zone is represented by an anomaly more than 500 meters in diameter that is mineralized and oxidized to a depth of more than 400 meters, as indicated by diamond drilling (News Release #10, May 28th 2010). This porphyry-class tonnage potential is demonstrated in Figure A1 that illustrates how a 108 million tonne (tonne = metric tonne) block fits within the priority drilling area of the West Zone. Note that the potential quantity, above, is conceptual in nature, there has been insufficient exploration to define a mineral resource, and it is uncertain if further exploration will result in discovery of a mineral resource.
Hole-averaged equivalent silver values for combined silver and gold, using a silver to gold ratio of 40:1, are mapped in Figure A2-as generated from data in Table A1. These hole-averaged equivalent silver values increase to the north to more than 20 grams per metric tonne. Higher grades are also open in this direction.
Hole-averaged assay data for silver and gold with a calculated silver equivalent grade (silver:gold calculated at 40:1) for all holes located in the West Zone on Figures A1 and A2 are in Table A1. The higher grades of hole-averaged equivalent silver encountered in these holes (Table A1 and Figs. A1 & A2) is emphasized by the large number of holes with greater than 20 grams per metric tonne of silver equivalent. These drill holes are:
1. DLS11RC007: 93.0 meters total length with 21.50 grams/metric tonne silver equivalent.
2. DLS11RC014: 102.0 meters total length with 31.99 grams/metric tonne silver equivalent.
3. DLS11RC015: 102.0 meters total length with 23.95 grams/metric tonne silver equivalent.
4. DLS11RC021: 87.0 meters total length with 27.70 grams/metric tonne silver equivalent.
5. DLS11RC030: 99.0 meters total length with 21.86 grams/metric tonne silver equivalent.
6. DLS11RC033: 67.5 meters total length with 32.40 grams/metric tonne silver equivalent.
7. DLS11RC060: 100.5 meters total length with 22.05 grams/metric tonne silver equivalent.
8. DLS11RC062: 87.0 meters total length with 27.59 grams/metric tonne silver equivalent.
9. DLS11RC064: 52.5 meters total length with 20.57 grams/metric tonne silver equivalent.
All mineralization is in a highly oxidized cap-rock of intensely muscovite altered porphyry or greisen. Consequently, the gold and silver mineralization is: (i) in rock with a low ―work indexΓÇû, and (ii) amenable to bulk heap leaching of oxide mineralization. Silver appears to be concentrated in manganese rich horizons, the distribution of which is being evaluated. Gold is associated with vein quartz. Associated tungsten, molybdenum, bismuth and lead could contribute to the value of the silver-gold mineralization, based on qualitative, in-house Niton XRF analyses (see News Release #08, August 10th 2011). Because drilling is preliminary, mineralization is open in all directions and at depth. Core recovery in diamond drilling was about 80% and recovery in reverse circulation drill holes was approximately 70%. The effect of this recovery on overall grade assessment is not known.
IN SUMMARY, the West Zone target is a 100 million tonne, porphyry-style, open-pit mine for bulk-tonnage low grade silver and gold. There are potentially additional values in tungsten, molybdenum, bismuth and lead. Mineralization occurs in an oxide zone and is expected to be heap leachable. Recovery of other minerals, such as the tungsten mineral wolframite, might be achieved by gravity methods. Metallurgical options are to be evaluated.

Figure A1. Drill holes currently completed on the West Zone of the Don Luis Property in Sonora, Mexico, are plotted as black dots. Holes DLS10DD01 & 02 and DLS11RC001 to 064 are plotted in this map and summarized in Table A1. The average assay of each hole for silver equivalent in grams per metric tonne is in Table A1 and contoured in Figure A2. The potential of this zone to contain 100 million tonnes is illustrated by the dark blue block plotted on top of the red priority drill area. The areas of both are about the same; the depth is estimated from the two diamond drill holes in the area (DLS10DD01 & 02) that were about 400 meters long and totally within oxidized, leached cap rock.

Figure A2. Drill holes completed on the West Zone of the Don Luis Property in Sonora, Mexico, are plotted as black dots with a size that reflects average silver equivalent in grams per metric tonne (legend: "GpTonne"). These values are also contoured. Values are higher to the northeast. Holes in the southwest have lower values, but this might be because these holes were short and failed to reach the deeper manganese-silver enrichment horizons.
