TK enters the final day of April with a striking six-week rally behind it — the TSXV-listed zinc explorer has climbed 71% over the past month to CAD 0.60, turning a coordinated October insider buying cluster into a compelling paper gain.
The ownership story is the real thread here. Last October, nearly every name on the board bought shares at CAD 0.275. CEO Graham Carman picked up approximately 360,000 shares. Director Brandon MacDonald and fellow director Michael Horner each added 900,000 shares. CFO Nick DeMare, the Chairman, and two independent directors all bought on the same day. Combined net purchases across the 90-day window topped 2.9 million shares. The stock has since more than doubled. That kind of synchronised buying from the full C-suite and board rarely goes unnoticed for long.
Short sellers have played almost no role in this story. Short interest is just 0.12% of the free float — a fraction so small it barely registers. The borrow market reflects the same indifference: cost to borrow has eased sharply to 3.49%, nearly half of where it was in mid-March when the rate was running above 8.5%. Availability has loosened dramatically too, with lending utilization now effectively at zero, down from a 52-week peak of 53.8%. There is no short-side pressure here and no meaningful squeeze dynamic to unwind. The ORTEX short score has dropped to 25.8, sliding from above 36 in mid-April as short interest itself fell 8.3% over the week. The borrow market is telling the same story the price is: sellers are stepping back.
Tinka's two largest institutional holders — Compañía de Minas Buenaventura and Hejoassu Administração — each hold around 12.2% of shares, providing a stable anchor at the top of the register. Combined, those two strategic stakes account for roughly a quarter of the company. That concentration limits the free float meaningfully and helps explain why even modest buying interest can move the price sharply.
Among correlated peers, the week has been choppier. RUP on the TSX fell 7.5% and IDR dropped nearly 10% over the same period. DAN, also on the TSXV, bucked the trend with a 6.5% gain. TK's modest 2.4% weekly pullback looks measured against that backdrop, particularly given the scale of the prior monthly move.
The next scheduled corporate event is May 26. With the stock more than doubled from the levels where insiders were buying six months ago, that release becomes the first real test of whether the operational story matches the re-rated price.
