On June 12, 2019 Metals Creek Resources Corp. (TSX-V: MEK) announced it has signed an option agreement with Newmont in which Metals Creek can earn a one hundred percent interest in the Dona Lake Gold Property located in Pickle Lake mining district, 9 km southeast of the town of Pickle Lake, Northwestern Ontario. The Property consists of 32 patented and leased mining claims totaling approximately 430.1 hectares and covers the past producing Dona Lake Mine. The Dona Lake Mine, an underground operation from 1989 to 1994 produced 246,500 ounces of gold at a grade of 7.44 grams per tonne. In 1994, when the mine closed, the average gold price was approximately $383.23 (US) per ounce. The Pickle Lake Greenstone Belt is host to several historic mines including the Dona Lake mine, the Central Patricia mine and the Pickle Crow mine. Dona Lake is accessible by an all-weather road southeast from the Town of Pickle Lake.
On July 8, 2020 Metals Creek announced that they had commenced drilling on the Dona Lake Project. They drilled 3 holes totaling 1411 meters, two shallow holes to test the Main Zone and B Zone and a deep hole to confirm the continuation of gold mineralization below the lower most level of the mine (455 level).
Hole DL20-001 was designed to test the continuation of gold mineralization south of the Dona Lake mine at 121m level below surface. The Main Zone returned a core length intercept of 4.53 g/t Au over 1m (139.00-140.00m). Mineralization consisted of 1 to 2% disseminated pyrrhotite with associated silicification and quartz veining.
Hole DL-20-002 was collared to test the continuation of gold mineralization immediately south of Dona Lake mine workings at approximately 220m below surface. The first zone which is interpreted to be the Main Zone and returned a core length intercept of 8.45 g/t Au over 3.15m (254.85-259.00m). This intercept was a part of a broader zone of mineralization returning a core length intercept of 5.67 g/t Au over 5.15m (254.85-260.00m). Mineralization is hosted within silicate-sulfide iron formation and characterized by stringer to semi-massive pyrrhotite ranging from 3 to 40% with local pyrite and magnetite. Alteration includes strong silicification with associated quartz veining and locally moderate to strong grunerite, garnet and biotite in conjunction with folding.
A second zone of mineralization further down hole returned a core length intercept of 2.34 g/t Au over 9.2m (278.60-287.80m). Mineralization is hosted within silicate-sulfide iron formation with 1 to 6 percent disseminated to stringer pyrrhotite as well as trace to 1 percent pyrite and local magnetite. Alteration consists of Strong silicification with quartz veining and local biotite, garnet and grunerite. This second zone of mineralization is interpreted to be B-Zone.
Hole DL20-003 was designed to test for the continuation of gold mineralization below the lower most level of the Dona Lake Mine (455 level). This hole penetrated the Main Zone at approximately 500m below surface and returned a core length intercept of 8.07 g/t Au over 7m (531.6 – 538.6 m). Included in this intercept is a high grade intercept of 17.6 g/t Au over 1 m. Mineralization is hosted within silicate-sulfide iron formation and characterized by stringer to semi-massive pyrrhotite ranging from 3 to 30% with local pyrite and magnetite. Alteration like that of holes 001 and 002 includes silicification with associated quartz veining and locally moderate to strong grunerite, garnet and biotite in conjunction with folding.

Gold mineralization at Dona Lake is hosted within three prominent banded iron formations with the middle iron formation hosting the Dona Lake Mine (Main Zone). The Main Zone remains open at depth with limited drilling along strike. Mining stopped at the 455 meter level with historic drill results below the 455m level that selectively include 13.62 g/t Au over 13.00m, 8.74 g/t Au over 3.9m and 8.57 g/t Au over 2.8m, indicating the continuation of high-grade mineralization at depth below the bottom level (455 Level) of the Dona Lake Mine. In addition company personnel have compiled data from the past producing Dona Lake Mine to try and determine what mineralization remains outside the area of selective historic mining. During compilation, it was determined that the deepest hole found to date was drilled approximately 100m below the mine workings of the Main Zone (455m). This hole (455-2) returned a down hole intercept of 4.36 g/t Gold over 21.08 meters indicating the continuation of mineralization at depth.
A second zone (B Zone), footwall to the Main Zone, was partially drilled off but only saw limited development and test mining, remaining open at depth with limited drilling along strike. B Zone is defined as a steeply plunging zone with selective historic intersections including 14.17 g/t Au over 15.31m, 9.9 g/t Au over 10.6m, 7.85 g/t Au over 5.85m and 12.44 g/t Au over 4.6m.
The company has flown an airborne time-domain Electro-Magnetic (EM) and Magnetics (Mag) Survey. From this survey two additional discreet magnetic trends have been delineated and may be indicative of oxide iron formations trending roughly parallel to iron formations that host the gold mineralization at the Dona Lake deposit. These discreet anomalies are located in an underexplored area of the Property and represent prospective targets requiring further exploration.
Currently there are four known gold bearing oxide iron formations that host gold mineralization on the Dona Lake Gold Project. It is interpreted that the more pyrrhotite rich sections of the iron formation within the Dona Lake deposit tend to exhibit a strong spatial relationship to increased gold mineralization. This could be a result of pyrrhotite replacing magnetite, decreasing the magnetite content and magnetic signature. With pyrrhotite being highly conductive, modeling of the recently completed airborne will prioritize targets exhibiting strong conductivity and weaker magnetic signatures.
