Executive Summary

Q4 2018 showed a larger quarterly loss as exploration spending ramped: net loss of $0.704M (−$0.01/share) vs −$0.487M (−$0.02/share) in Q4 2017; cash ended at $0.111M and working capital was −$0.228M as of Sep 30, 2018 .
FY18 loss widened to −$5.058M (−$0.13/share) from −$1.646M (−$0.06/share) in FY17, primarily due to a previously disclosed $3.2M Talapoosa abandonment/write-off in Q2 FY18 .
Management highlighted successful exploration catalysts in Q4: discovery work confirming a copper–molybdenum–gold–silver porphyry at Elder Creek and recognition of higher-grade Carlin-type gold occurrences at Lookout Mountain and Windfall; follow-up drilling is planned .
No Wall Street consensus estimates were available from S&P Global for Q4/FY18; thus beat/miss analysis versus estimates is unavailable (S&P Global data unavailable for TLRS).

What Went Well and What Went Wrong

What Went Well

Elder Creek confirmation: Initial Q4 drill program confirmed a large porphyry system; notable intercepts include 110 ft @ 0.44% Cu in RCEC18-01 and 46.5 ft @ 1.20% Cu, 0.31% Mo, 25.5 g/t Ag, 0.126 g/t Au in core interval of CCEC18-02, with mineralization open laterally and at depth .
High-grade surface sampling at Windfall: 40 rock-chip samples returned up to 13.1 g/t Au; 10 samples >1 g/t and 6 samples >3 g/t, supporting drill targeting and resource potential in Q4 .
Strategic portfolio progress: Completed acquisition of Elder Creek and Paiute JVs and increased Q4 exploration investment to advance multiple Nevada targets; CEO: “we increased our investment in exploration…documented the existence of a mineralized copper-molybdenum-gold-silver porphyry at Elder Creek…recognition of higher-grade Carlin-type gold occurrences at Lookout Mountain and Windfall” .

What Went Wrong

Losses expanded with limited liquidity: Q4 net loss −$0.704M; cash only $0.111M and working capital −$0.228M as of year-end, highlighting funding risk .
FY18 P&L impacted by Talapoosa exit: Q2 included a $3.2M write-off after terminating the Talapoosa option; FY18 loss rose to −$5.058M from −$1.646M in FY17 .
Consensus/coverage thin: No S&P Global consensus EPS/revenue estimates available, limiting institutional benchmark comparisons (S&P Global data unavailable for TLRS).

Management Commentary

“In Q4, we increased our investment in exploration with an initial drill program which documented the existence of a mineralized copper-molybdenum-gold-silver porphyry at Elder Creek. At Eureka, our reassessment of the property lead to recognition of higher-grade Carlin-type gold occurrences at Lookout Mountain and Windfall…we plan follow-up on each of these projects with further drilling.” — Steve Osterberg, CEO .
“We have strengthened and solidified our Board…advancing the acquisition of the Elder Creek and Paiute projects…With excellent results from recent geological work and sample assays, we plan follow-up…including strategic drilling.” .
On Q2 pivot after Talapoosa termination: “We are refocusing our efforts on projects in the Battle Mountain–Eureka gold trend… and gaining strong, strategic partners.” .

Q&A Highlights

Estimates Context

Wall Street consensus EPS and revenue estimates for TLRS were unavailable from S&P Global for Q4/FY18 (S&P Global data unavailable for TLRS).
Implication: No beat/miss framing; investor focus should remain on funding runway, work-program milestones, and technical de-risking progress rather than near-term financial estimates.

Key Takeaways for Investors

Technical traction: Q4 drilling at Elder Creek and high-grade sampling at Windfall support a growing technical case at both porphyry and Carlin-type targets; near-term geophysics and follow-on drilling are key catalysts .
Funding watch: Year-end cash of $0.111M and negative working capital of −$0.228M, coupled with going-concern language, imply a need for near-term financing/partnerships to sustain planned programs .
Program cadence: Elder Creek IP/Resistivity survey (early 2019) and permitted drilling thereafter can create news flow; execution on earn-in spending milestones remains important .
Portfolio repositioned: Exit from Talapoosa (Q2) removed a drag but created a loss; focus now squarely on Nevada assets with JV partners McEwen and Barrick subsidiaries, with TLRS as operator on key projects .
No consensus anchor: With no S&P Global estimates, trading may be more headline/assay-driven; expect volatility around technical updates and financing events.
Management stability: CFO transition addressed; certifications and engagement letter underscore functional finance leadership through FY18 reporting .
Risk/reward skew: Early-stage exploration risk and financing needs are material; upside tied to validation of porphyry center(s) at Elder Creek and delineation of higher-grade Carlin-style zones at Eureka .
