Gold and Silver Updates


  • Exploration drilling underway on the Black Sheep goal and Florida Mountain Deposit, marking the primary winter exploration program on the DeLamar Mission.
  • The 2021 exploration drill program at DeLamar will complete 10,000 meters (“m”), together with follow-up drilling on the profitable 2020 high-grade drill program at Florida Mountain and Warfare Eagle, in addition to low-grade, heap-leachable extension drilling at Florida Mountain primarily to the east and west of the prevailing useful resource envelope. Henrietta Ridge, the un-tested northern extension of the DeLamar useful resource, in addition to choose targets within the Black Sheep space will even be drilled this yr.
  • The Firm’s Pre-feasibility Examine (“PFS”) is on-schedule for supply in This fall 2021. As a part of this PFS, Integra has undertaken a number of trade-off research aimed toward recovering extra silver (“Ag”) than was contemplated within the 2019 Preliminary Financial Evaluation (“PEA”). These research embrace:
    • Elevated mill measurement to recuperate extra silver: Historic mill recoveries for silver at DeLamar had been between 75% and 80%, considerably increased than the silver recoveries within the Firm’s PEA which centered extra on heap-leaching (27,000 tonnes per day) than milling (2,000 tonnes per day). The DeLamar Mission has a big silver useful resource of 116,514,000 ozs of silver (172,365,000 tonnes grading 21 g/t Ag) within the Measured and Indicated class and 12,240,000 ozs of silver (28,266,000 tonnes grading 13.5 g/t Ag) within the Inferred class.
    • Different processing choices to extend potential mill measurement and silver restoration: The Firm is finding out the potential of processing extra oxide and transitional materials in a mill via agitated leach strategies in addition to Excessive Stress Grinding Rolls (“HPGR”) as a pre-cursor to heap leaching, each of that are designed to enhance silver and gold recoveries.
  • The Firm has continued an in depth metallurgical testwork program at DeLamar and Florida Mountain, together with:
    • 19 column leach checks on oxide and transitional materials from Florida Mountain
    • 7 variability composites for unoxide materials from Florida Mountain
    • 44 variability composites deliberate on oxide and transitional materials from DeLamar
    • 10-15 variability composites on unoxide materials from DeLamar

VANCOUVER, British Columbia, Jan. 21, 2021 (GLOBE NEWSWIRE) — Integra Assets Corp. (“Integra” or the “Firm”) (TSX-V:ITR; NYSE American: ITRG) is happy to announce exploration plans for 2021 on the DeLamar Mission (“DeLamar” or the “Mission”) situated in Owyhee County in southwest Idaho together with an replace on the PFS and varied trade-off research presently being thought of by the Firm for the PFS in This fall 2021.

“This yr shall be pivotal for Integra as we proceed to develop the gold-silver useful resource on the Mission via exploration drilling whereas getting ready to ship a PFS in This fall 2021. The Firm appears to be like ahead to following-up on its drill success at Florida Mountain and Warfare Eagle in addition to the primary exploration program at Black Sheep which has the potential for a brand new discovery on the DeLamar Mission. The winter drill program on the Mission is presently underway with on drill rig on the Fortunate Days goal located within the Black Sheep space and one drill rig on the Florida Mountain Deposit,” famous Firm President and CEO George Salamis. “In anticipation of the Firm’s PFS in This fall 2021, we’re conducting varied trade-off research to unlock extra worth at DeLamar via, amongst different initiatives, elevated silver recoveries. The DeLamar and Florida Mountain Deposits are host to vital silver assets, along with gold, making the Mission one of many largest undeveloped silver-gold assets within the Western United States. Within the 2019 PEA, silver accounted for less than 17% of the estimated mission revenues because the examine was optimized for gold-and-silver costs at the moment. The low silver income relative to gold income was largely associated to 2 components: low heap leach recoveries of silver averaging 34% over life-of-mine and a smaller milling situation of two,000 tonnes per day which might recuperate on common 80% silver over life-of-mine. Given the massive silver endowment at DeLamar, the Firm can also be reviewing various eventualities to extend silver restoration, together with a bigger milling operation designed to accommodate oxide and transitional materials to be processed by way of agitated leach and HPGR as a pre-cursor to heap leaching. Growing silver recoveries may have a materially constructive impact on the mission’s future economics.”

Present Pre-feasibility Stage Research Geared toward Enhanced Silver Recoveries:

A number of key trade-off research are presently under-way, aimed to outline the cost-benefit of upper steel recoveries, particularly silver, in future growth eventualities at DeLamar.

Latest metallurgical testwork because the 2019 PEA is being analyzed for alternatives to enhance silver restoration. A deeper analysis into the scale sensitivity of each gold and silver restoration is underway, to be included on this yr’s PFS. This contains consideration of HPGR know-how within the closing stage of the crushing circuit for the heap leach course of and/or implementation of a bigger milling and agitated leach circuit for increased grade transitional mineralization, each of which might successfully produce finer crushed materials with enhanced silver restoration potential.

Processing extra transitional mineralization via a mill circuit may probably yield better general steel restoration, together with silver, than via placement of crushed materials on the leach pad.

Florida Mountain unoxidized materials is processed via the prevailing milling situation within the PEA. Testwork has proven that the unoxidized materials from Florida Mountain is amenable to gravity focus, adopted by flotation of the gravity tails, with regrinding and agitated cyanide leaching of the flotation focus. Mill recoveries on this materials within the PEA had been 90% for gold and 80% for silver with a comparatively course grind measurement of 212 µm. The Firm is finishing extra testwork on the DeLamar unoxidized mineralization which was not included within the PEA. This testwork contains varied pre-cyanidation remedies choices, together with tremendous grinding and pre-aeration, and shall be reevaluated with present steel costs and higher outlined prices.

The Firm will present updates and steering on how these trade-off research are progressing over the course of the yr.

2021 Exploration Program

The Firm has plans for a ten,000 m exploration program in 2021. The drill program will deal with the next areas:

The Florida Mountain Deposit: 4,000 m:

One among two exploration drill rigs on the Mission will function at Florida Mountain via the winter months. Drilling at Florida Mountain shall be dual-focused, together with follow-up exploration on the high-grade shoots and buildings under the prevailing useful resource and increasing the prevailing low-grade useful resource via drilling geochemical and geophysical anomalies to the east and west of the prevailing useful resource.

The Firm has recognized a number of high-grade gold-silver shoots at Florida Mountain. Integra’s exploration workforce has modeled 7 high-grade vein buildings that seem comparable in measurement and orientation to the traditionally productive high-grade Commerce Greenback – Black Jack vein system. Most historic underground manufacturing stemmed from the Commerce Greenback – Black Jack vein, whereas the remaining 6 veins noticed restricted manufacturing up till mining operations ceased with the beginning of World Warfare I. The recognized vein zones have an combination strike size of over 7,000 m. Inside these vein zones are steeply dipping high-grade shoots with strike lengths of as much as 200 m and down dip extensions of as much as 300 m that are interpreted as having developed at structural intersections. Primarily based on current drill intercepts, the Firm anticipates that the high-grade shoots are more likely to have widths of between 1 m and eight m.

Drilling can also be deliberate to happen within the Florida Keys space, a big geochemical anomaly situated instantly to the east of the useful resource that has seen restricted drilling. The Florida Keys geochemical anomaly is of comparable power and measurement to the prevailing useful resource estimate footprint on the Florida Mountain Deposit. The Firm additionally intends to drill in Wealthy Gulch, a goal situated in a big zone of Induced Polarization (“IP”) chargeability that was recognized to the west of Florida Mountain as a part of a 2020 geophysical survey. Primarily based on restricted historic drilling and the presence of historic underground workings on this space the Firm sees potential for each extra low-grade and high-grade underground mineralization.

Warfare Eagle Mountain: 2,000 m

In the course of the 2019 and 2020 drill applications at Warfare Eagle, the Firm intersected high-grade gold-silver mineralization inside the volcanic unit overlying your entire space. In 2020, the Firm recognized a second high-grade shoot 400 m to the north of the 2019 drill holes. This second construction is interpreted over a strike size of roughly 550 m south-southeast and is basically untested. The geochemical soil anomaly that led the Firm to this new construction is interpreted as being lateral leakage outward alongside the bottom of the latite circulate, presumably emanating from the jap most construction recognized within the 2020 drill program.

Drilling in 2021 will proceed to check these parallel buildings at Warfare Eagle. As well as, the Firm plans on finishing an in depth IP program to generate targets inside a big geochemical anomaly to the east of the 2019 and 2020 drill holes places.

Black Sheep and DeLamar (Henrietta Ridge): 4,000 m

Exploration drilling at Black Sheep is underway with one drill rig anticipated to function via the winter months. The drill marketing campaign at Black Sheep will deal with the Georgianna and Fortunate Days targets. Black Sheep is host to in depth areas of sinter and opaline silica lower by high-level epithermal veining and brecciation. As a result of shallow degree of abrasion at Black Sheep, very restricted exploration drilling accomplished by earlier operators was proven to be too shallow to correctly consider the potential for high-grade vein type mineralization.

Two shallow drill holes have been accomplished on the Georgianna goal to raised outline the buildings controlling mineralization. Deeper, follow-up drill holes are deliberate on the Georgianna goal for this yr to check the productive zone at roughly 200 m under the present floor.

The Firm additionally plans on drilling the Henrietta Ridge goal in 2021. Henrietta Ridge is situated between the DeLamar Deposit and the Black Sheep space. Historic drilling accomplished by earlier operators together with geophysical surveys recommend mineralization from the DeLamar Deposit extends alongside a northwest hall from the present useful resource via Henrietta Ridge.
