Colorado Defines Gold-Copper Mineralization Over 500 m Strike Length at Tami
VANCOUVER, British Columbia, Nov. 16, 2018 (GLOBE NEWSWIRE) -- Colorado Resources Ltd. (“Colorado” or the “Company”) (TSXV – CXO) is pleased to announce completion of the 2018 drilling program at its KSP property, located in British Columbia’s prolific Golden Triangle region (see news release dated June 6, 2018).

|||||||||||||||
A total of 7,693 meters (“m”) of diamond drilling were completed testing four target areas; Tami, A-J, Pins Bowl and Inel, (Map 1). Results from 2,121 m of the program drilled at Inel were reported in a news release dated September 14, 2018.
TAMI
A total of 4,115 m of diamond drilling in 18 holes was completed at Tami (Map 2 and Table 1, below) to follow up on results from the 2017 discovery program which delineated contiguous copper-gold mineralization over 400 metres strike associated with a large high tenor copper gold soil anomaly. Significant results from 2017 included drill holes TMDDH17-115 returning 40 m grading 1.74 g/t Au with 0.24% Cu, TMDDH17-118 returning 114.6 m grading 0.69 g/t Au with 0.17% Cu (including 39 m grading 1.11 g/t Au with 0.18% Cu), and, TMDDH17-120 returning 38 m grading 1.00 g/t Au with 0.11% Cu.
Highlights from 2018 include drill hole TMDDH18-145, a step-back drilled 100m to the SW of hole TMDDH17-115, which contained 45 m grading 0.80 g/t Au with 0.22% Cu, extending mineralization down-dip where it remains open along the strike length of the Tami zone. 2018 drilling also tested along trend on the Cu-Au soil anomaly, more than doubling strike length of the hosting structural corridor with a 400m step out to the east and 50m step out to the west. Mineralization remains open in all directions.

1 Widths (m) reported are drilled core lengths. True widths are estimated at 50 to 70 per cent of drilled lengths.

Gold-copper (“Au-Cu”) mineralization at Tami is associated with at least three phases of early Jurassic, equigranular and porphyritic monzonite, occurring as sills and dykes cutting mafic tuffs and sedimentary rocks of the Hazelton Group. Disseminated and veinlet-hosted mineralization and associated hydrothermal alteration affecting both the intrusive and volcano-sedimentary rocks is contained within an east-west structural corridor extending for over 800 m along strike, coincident with a strong Au-Cu geochemical anomaly (Map 2).
Additional drilling at Tami tested numerous composite Au-Cu geochemical and geophysical (magnetic) anomalies located within the approximately 2 square kilometre area surrounding the Tami prospect. This drilling identified similar, localised, porphyry-related mineralization and alteration patterns associated with anomalous gold values in several drill holes (see Map 2 and Table 1) which compel future follow-up drill testing. Several coincident Au-Cu anomalies also remain untested by drilling.
Colorado President and CEO, Robert Shaw, states: “Our 2017-2018 drilling has outlined a core zone of shallow Au-Cu mineralization in bedrock, extending for approximately 850 m along strike between holes TMDDH18-135 and TMDDH18-139, with down-hole widths of up to 100 m (1). This zone provides us with an excellent target for 2019 step back drilling to test mineralization which remains open down dip.”
A-J
During the 2018 field season the Company completed 9.6 km of IP and ground magnetic surveys over the A-J target area (Map 3). Previous highlights from channel sampling in 2014 included 26.2 g/t Au over 2 m, 22 g/t Au over 2 m, and 31 g/t Au over 2 m. Two well defined chargeability anomalies were outlined over strike lengths of 500 m in the vicinity of outcropping skarn mineralization.
Colorado’s 2018 initial drilling campaign targeted the high-grade zone delineated by 2014 channel sampling along with coincident IP and gold-in-soil geochemical anomalies. The program comprised 7 drill holes totalling 1,457 m, distributed over a strike length exceeding 500 m (Map 3). A-J represents a gold-rich skarn hosted in Upper Triassic Stuhini Group characterized by lower limestone members intercalated with bimodal pillowed andesites, volcaniclastics, felsic tuffs and volcanic derived sediments. Drilling results, which included encouraging gold intercepts in AJDDH18-130 & 133, and a high grade zinc intercept inf AJDDH18-133, are shown in Table 2, below. Core logging and bedrock geological interpretation is ongoing to put the intercepts in context with the geologic model and identify a follow-up strategy for 2019.

Colorado President and CEO, Robert Shaw, states: “Our reconnaissance drilling at A-J has identified a sizeable alteration system containing abundant pyrite, pyrrhotite, carbonate and secondary silica. Assay values received from core samples however do not reflect the high grade values returned from Colorado’s historic surface sampling programs. Additional surface work will be required to better define the nature and the distribution of the high-grade mineralization previously sampled at A-J.”
PINS BOWL
The Pins Bowl prospect is located approximately 7 km to the south of Tami (Map 1). Past Colorado prospecting and geological mapping along the east-west striking Sky-Kyber fault corridor identified centimetre- to decimetre-scale quartz-chalcopyrite vein mineralization which returned in situ chip-sample values up to 3.45% Cu and 2.15 g/t Au. Additional outcrop grab/float samples returned 2.44% Cu with 1.3 g/t Au, 0.37% Cu with 4.8 g/t Au and 1.22% Cu with 0.1 g/t Au. Strong quartz-magnetite stockwork veining in out crops of altered monzonite intrusive returned sample values of 0.93% Cu with 0.28 g/t Au and 0.48% Cu with 0.18 g/t Au. 2018 drilling comprised a single drill hole, PNDDH18-140, totalling 201 m, to test a 100+ m wide corridor of deformed and hydrothermally altered monzonite intrusive containing disseminated and stockwork veinlet-hosted chalcopyrite mineralization. Analytical results from drill core returned anomalous values including 66 m grading 0.12% Cu within the monzonite intrusive. The nature and east-west trend of Pins Bowl mineralization suggests additional exploration along the Sky-Kyber fault corridor is warranted.

Quality assurance/quality control procedures
Colorado has implemented a rigorous quality assurance/quality control (QA/QC) program to ensure best practices in sampling and analysis of diamond drill core, the details of which can be viewed on the Company's website.
All assays are performed by ALS Canada Ltd., with sample preparation carried out at the ALS facility in Terrace, B.C., and assays at the North Vancouver laboratory. Assay values are uncut. For gold, fire assays are performed as per ALS method Au-AA26 (0.01 to 100.00 g/t Au) using 50 grams of sample measured by atomic absorption (AA). Assays equal to or greater than 10.0 g/t Au are reanalyzed gravimetrically by method Au-GRA22. Silver, copper and zinc are analyzed by ALS method ME-MS61 with a four-acid digestion followed by ICP-MS (inductively coupled plasma mass spectrometry) analysis. ME-MS61 Values greater than the upper detection limit are continued with ore grade analysis (OG62).
