Rockhaven Resources Ltd. is an exploration company aggressively advancing its 100% owned, road accessible Klaza gold-silver project located in Yukon, Canada.
The Klaza property is located 50 km west of Carmacks, Yukon and is road accessible a two-wheel drive road from the Klondike Highway. Rockhaven's exploration to date has included over 78,000 m of diamond drilling, 20,000 m of excavator trenching; extensive soil geochemistry; and magnetic, radiometric, IP and VLF-EM surveys.
Most of the Klaza Property is underlain by Mid-Cretaceous granodiorite. A Late Cretaceous granite to quartz monzonite stock intrudes the granodiorite and is thought to be the main heat source for hydrothermal cells that deposited mineralization along a series of northwesterly trending, structural conduits. A series of northwesterly trending feldspar porphyry dykes emanate from the stock and cut granodiorite in the area of the Klaza Deposit. Klaza Deposit mineralization is hosted in eleven known structural zones, ranging from 1 m to 100 m in width most of which occur along side porphyry dykes. These structural zones collectively form a 2 km wide by 4.5 km long corridor within the granodiorite.

KLAZA DEPOSIT MINERAL RESOURCESRockhavenRESOURCES LTD.
The Klaza Deposit hosts an inferred mineral resource estimate that includes 1.36 million ounces gold grading 4.48 g/t and . 26.96 million ounces silver grading 89.02 g/t
Mineralization comprises disseminated to semi-massive pyrite, arsenopyrite, galena, sphalerite, chalcopyrite, stibnite, tetrahedrite and jamesonite in quartz, carbonate and barite gangue. The relative proportions of sulphide minerals vary with each zone and with distance from the porphyry centre. The sulphide minerals typically comprise 1% to 10% of veins and altered wallrocks, often increasing to between 20% and 80% over 25 cm to 200 cm intervals.
Eleven known vein zones have been identified within the area of the Klaza Deposit. The most extensively explored zones, the BRX and Klaza zones have each been trace along strike for 2,400 m and to depths of 520 m and 325 m down-dip, respectively. Neither zone outcrops, but mineralization has been exposed along the known length of the each zone in excavator trenches, beneath a 1 m to 2 m thick veneer of overburden. Mineral resources currently include the Klaza and BRX zones, and parts of the BYG and Pika zones. All zones are open for expansion along strike and down-dip.

MINERAL PROCESSING AND PEARockhavenRESOURCES LTD.
In March 2016, Rockhaven completed a PEA that presents a conceptual mine and milling plan using the December 2015 mineral resource.
Mineral resources from the western and central portions of the Klaza and BRX zones would be extracted using a combination of contractor open pit and owner-operator longhole open stoping underground mining methods. The process facility is designed to operate at 1,500 tpd and will feature standard crushing, SAG and ball mill grinding followed by sequential lead, zinc and arsenopyrite flotation circuits. The arsenopyrite concentrate will then be treated by pressure oxidation and cyanide leaching to recover gold. The lead concentrate will be leached to recover gold and silver using an Acacia intensive cyanide leach process.

Rockhaven is committed to advancing the Klaza Project through further exploration and exploring potential opportunities to enhance project economics, including:
Resource expansion:
Pre-concentration:
Mineralized veins, and veinlets comprises medium to coarse grain sulphides. Gold occurs both as discrete grains and in solid-solution in both arsenopyrite and pyrite. Pre-concentration testwork will focus on density separation techniques at a coarse crush. Successful tests could reduce cut-off grades and processing costs.
hosted within granodiorite,
Mineral resources currently only include the Klaza and BRX zones, and parts of the BYG and Pika zones. No resources have been estimated on the other seven zones. All zones are open for expansion along strike and down-dip. Currently, low-grade mineralization found in the footwall of the Central Klaza and in the Eastern BRX are not included in the mineral resource estimate.
Exploration:Exploration on the 254 square kilometre Klaza property has included airborne and ground magnetic, radiometric, IP and VLF-EM surveys, and extensive soil geochemistry. Alteration adjacent to the known vein zones is associated with coincident linear magnetic lows and VLF-EM conductors. Many anomalies with similar signatures have not yet been tested.
East of the Klaza resource area, porphyry mineralization is hosted within a quartz monzonite stock and is known as the Kelly porphyry zone. The extend of this porphyry system has been delineated by a IP survey conducted in 2016, which identified a 2,400 m by 2,200 m sub-circular chargeability anomaly containing greater than 40 ms values with a 1,700 m by 800 m core with greater than 50 ms values. Only two diamond drill holes have tested this IP anomaly and have intersected alteration and mineralization consistent with those found in calc-alkaline porphyry deposits. Mineralization in these holes consists primarily of pyrite with lesser chalcopyrite and molybdenite.
