Rodeo Creek Property – Carlin Trend, Nevada

Rodeo Creek Property – Carlin Trend, Nevada -Trio owns a 100% interest in the Rodeo Creek property which is located at the north end of the famed “Carlin Trend” in Elko County, Nevada, and approximately 56 km northwest of the town of Carlin. The property comprises 29 contiguous mineral claims covering an area of 547 acres (221 hectares).

The salient points regarding this property are as follows:

Strategically located 1.5 kilometers northwest of Barrick Gold Corp’s Storm deposit, 3 kilometres northwest of their South Arturo discovery, and 8 kilometres northwest of the famed Meikle Mine.

The Carlin Trend, currently the most prolific gold mining area in North America, is host to as many as 30 gold mines and advanced projects, on which a combined 100 million ounces of gold production and inventory had been identified to 2002 (USGS), including world‑class deposits such as the Carlin, Goldstrike and Meikle Mines,

Recent mine discoveries in this camp are in the 1.5M to 5.0M ounce category, at grades in excess of 0.3 oz/t Au, all from “Carlin-type” sedimentary and structural type gold mineralization,

Previous drilling on the property confirms that Rodeo Creek exhibits the geological and alteration features common to many Carlin deposits; namely NW & NE control-faults, as well as halos of decalcification and silicification alteration within the highly prospective Popovich Formation, host to more than 85% of all deposits along the Carlin Trend,

The property also contains the anomalous geochemical signature of Carlin Trend deposits (Au-As-Sb-Tl) in alteration halos within the Popovich Fm and as “leakage anomalies” along the NW & NE-trending faults,

One such “leakage” anomaly (Flower Zone) has drill intercepts of up to 9.60 gm/T Au (0.28 oz/t) across 6m, including 29.10 gm/T Au (0.85 oz/t) over 1.5m. Mineralization occurs in a small fault-bound block within 90m of surface. It is believed to represent a strong leakage anomaly derived from underlying Carlin-type gold mineralization. Other “leakage” anomalies occur as intensely altered gold-bearing NE-trending fault zones (eg, Look and Flower faults) accompanied by large gold-arsenic soil anomalies traceable for more than 500m of strike length. These anomalies are believed to represent leakages from deeper Carlin-type gold mineralization,

To date, eleven holes deep enough to reach the Popovich Fm have been drilled on the property. In 1996/97, at the north end of the property, hole DD96-1C encountered 27m of hydrothermally altered Popovich Fm grading 0.89 gm/T Au (0.025 oz/t). In the west, DD96-2A intercepted 7m of 0.42 gm/T Au in similar alteration. In 2003 and 2010, six holes drilled on “leakage” anomalies in the south and west parts of the property encountered significant Carlin-style alteration in the basal part of the Popovich Fm. For example, AMK10-01 intercepted 0.17 gm/T across 27m, and AMK10-03 hit 0.18 gm/T over 15m which is highly anomalous for the Carlin Trend. The alteration is anomalous in Carlin‑type pathfinder elements and is consistent with alteration halos surrounding Carlin‑type gold deposits, demonstrating that the type of hydrothermal activity that produced mineral deposits along the Carlin Trend was present at Rodeo Creek. The most intense basal-Popovich alteration was encountered below the Flower target area, but was found to be barren. Despite the low gold values, the high-intensity alteration met in all of these holes requires follow-up drilling.

In 2011 an enhanced geological study was initiated to re-evaluate the control structures that cross the property and that are believed to be associated with nearby gold deposits. The NW-trending Arturo fault zone (AFZ), which is reportedly related to the Storm, Dee and South Arturo deposits located immediately south of Rodeo Creek, remains one of Trio’s most important targets, notably where it intercepts the Look and Flower fault zones; more particularly where the junction between these faults plunges through the Popovich Fm.

Other areas that merit follow-up exploration are the “Flower” and “North” targets, located on the auriferous Flower fault system, as well as the “West” and “Arsenic” targets, located on the Antelope fault system. The N-trending Antelope and North faults are key targets because similar N-trending faults elsewhere in the Carlin Trend have been found to be important conduits for gold mineralization. The North and Arsenic areas have not yet been drill-tested.

The Rodeo Creek property is considered to have very high potential for the discovery of one or more gold deposits similar to those presently being mined elsewhere on the Carlin Trend. Five geochemically anomalous target areas outlined for further exploration are still untested.
